In vivo investigation of the anti-liver fibrosis impact of Balanites aegyptiaca/ chitosan nanoparticles.

Balanites aegyptiaca (B. aegyptiaca) is an African herb with traditional medical applications. Various pathogenic factors cause hepatic fibrosis and require novel treatment alternatives. Nanoformulation-based natural products can overcome the available drug problems by increasing the efficacy of natural products targeting disease markers. The current study investigated B. aegyptiaca methanolic extract using high-pressure liquid chromatography (HPLC), and B. aegyptiaca/chitosan nanoparticles were prepared. In vivo, evaluation tests were performed to assess the curative effect of the successfully prepared B. aegyptiaca/chitosan nanoparticles. For 30 days, the rats were divided into six groups, typical and fibrosis groups, where the liver fibrosis groups received B. aegyptiaca extract, silymarin, chitosan nanoparticles, and B. aegyptiaca/chitosan nanoparticles daily. In the current investigation, phenolic molecules are the major compounds detected in B. aegyptiaca extract. UV showed that the prepared B. aegyptiaca /chitosan nanoparticles had a single peak at 280 nm, a particle size of 35.0 ± 6.0 nm, and a negative charge at - 8.3 mV. The animal studies showed that the synthetic B. aegyptiaca/chitosan nanoparticles showed substantial anti-fibrotic protective effects against CCl4-induced hepatic fibrosis in rats when compared with other groups through optimization of biochemical and oxidative markers, improved histological changes, and modulated the expression of Col1a1, Acta2 and Cxcl9 genes, which manage liver fibrosis. In conclusion, the current research indicated that the prepared B. aegyptiaca/chitosan nanoparticles improved histological structure and significantly enhanced the biochemical and genetic markers of liver fibrosis in an animal model.

Revealing how phenytoin triggers liver damage and the potential protective effects of Balanites Aegyptiaca fruit extracts: Exploring Nrf2/MAPK/ Beclin-1 signaling pathways.

Phenytoin-induced liver injury (PHT ILII) is a serious condition that may necessitate discontinuation of the drug. This study investigates the mechanisms of PHT ILII and evaluates the protective effects of Balanites Aegyptiaca (BA) fruit extracts on the liver. We focus on the Nrf2/MAPK/NF-κB/Beclin-1 signaling pathways involved in oxidative stress and inflammation from drug-induced liver injury. Phytochemical analyses of BA fruit extracts (Bu-F and EA-F) are conducted. Molecular docking techniques explore the interaction between phenytoin (PHT) and the Nrf2/MAPK/NF-κB/Beclin-1 pathways. Thirty-six male rats are divided into Control, Bu-F, EA-F, PHT, Bu-F/PHT, and EA-F/PHT groups, and they are observed for 45 days. EA-F extract is rich in phenolics/flavonoids, while Bu-F extract mainly contains saponins.PHT ILII causes histological damage in liver tissues and affects Nrf-2, MAPK, TNF-α, IL-1ß, Mcp-1, Beclin-1, iNOS expression, and liver function markers (ALT, AST, ALP). However, EA-F/Bu-F extracts effectively improve the histological structure and significantly reduce biochemical/immunohistochemical parameters, restoring them to near-normal levels. EA-F extract is particularly effective.In conclusion, the Nrf2/MAPK /Beclin-1 pathways play a critical role in the development of PHT ILII. BA fruit extracts show promise as hepato-protective agents, with the EA-F extract demonstrating superior efficacy. These results lay the groundwork for new treatments for PHT ILII and drug-induced liver injuries.

The effect of balanities aeqyptiaca defatted protein meal and protein concentrate supplemented diet on biochemical and molecular stability of diabetic wister albino rat.

Balanites aeqyptiaca (BA) seeds were toasted at 70 °C, milled and the oil expelled to resolve to meal which were defatted to resolve to defatted balanites aeqyptiaca (BA) protein meal and (BA) protein concentrate respectively. These were subjected to analysis using standard methods. There exist marked trend between defatted balanites aeqyptiaca protein meal, protein concentrate and incidences of diabetes. This work investigated the anti- diabetic effects of balanites aeqyptiaca defatted protein meal and concentrate supplemented diets in streptozotocin (STZ)-induced diabetic rats. The rats were fattened for two weeks with high fat diet (HFD) to introduce Hyperglycemia and then made diabetic by intraperitoneal administration of STZ (35 mg/kg body weight) and fed diets containing 5 % defatted balanites aeqyptiaca protein meal (DAPM) and 5 % balanites aeqyptiaca protein concentrate (APC) for 14 days. The effect of the diet on blood glucose, serum glutathione peroxidase (GPx), glutathione transferase (GSH), thiobarbituric acid reactive species (TBARS), α-amylase and intestinal α-glucosidase activities were investigated. There was marked increase in the blood glucose, TBARS, pancreatic α-amylase and intestinal α-glycosidase with corresponding decrease in serum GPx and GSH contents in diabetic rats control groups. These trends were however, reversed in diabetic rats fed diet supplemented with the balanites aeqyptiaca protein meals for 14 days. The meals from defatted and protein concentrate inhibit α-amylase and α-glycosidase inhibitory activity in vivo. Thus, the anti-diabetes properties of the defatted meal and protein concentrate may be attributed to the influence of its constituent phytochemicals on starch digestion as well as endogenous enzymes activities. The study revealed that defatted aduwa meal and proteins concnentrate demonstrated potentials used as functional ingredients in food materials and could also increase income access of low resource populace.

Variation of Secondary Metabolite Contents and Activities against Bovine Diarrheal Pathogens among Zygophyllaceae Species in Benin and Implications for Conservation.

Balanites aegyptiaca is a wild plant species largely used in folk medicine and a priority fruit tree in West Africa. In Benin, its overexploitation for ethnoveterinary uses could lead to its rarity or extinction in the long term. In this study, we evaluate the possibilities of its substitution by other Zygophyllaceae species. This study was based on optimal defense theory, which distinguished 2 categories of plants: K-strategist species and r-strategist species. Phytochemical screening was carried out based on aqueous extracts of the leafy stems of B. aegyptiaca and Guaiacum officinale (K-strategist species) and Tribulus terrestris and Kallstroemia pubescens (r-strategist species) for the identification of chemical compounds. The phenolic compounds were quantified by quercetin and vanillin methods. The extracts were tested against 5 bacterial strains responsible for severe diarrhea in bovines. Our results indicated the presence of many phytochemicals, such as alkaloids, flavonoids, saponosides, and tannins. The diversity in secondary metabolites is higher for r-strategist than K-strategist species. The contents of total polyphenols ranged from 4.82 ± 0.05 to 41.84 mg GAE/g of extract. The flavonoid contents varied from 30.64 ± 0.35 to 57.11 ± 0.13 mg QE/g of extract and those of the tannins from 0.04 ± 0.00 to 0.06 ± 0.01 mg PE/mL. The sensitivity of the bacterial strains showed a significant dependence on the extracts. Of the species, K. pubescens showed a bactericidal activity on the majority of strains tested and thus could be a potential substitute for B. aegyptiaca in the treatment of infectious diarrhea.

A comparative appraisal of three important oil yielding plants for their biodiesel potential.

In the present scenario, alternative energy sources are required to achieve the future economic prosperity where shortage of fossil fuels will be a limiting factor and hamper the global economic growth. Therefore, interest in biofuel is increasing continuously. The best way of sustainable development is fossil fuel supplementation with biodiesel to reduce the fossil fuel demand. Biodiesel is a clean burning, ester-based, oxygenated fuel derived from natural and renewable sources. Till now, majority of the people have worked on the biodiesel derived from edible oil. Instead of using edible oil, non-edible oil needs to be explored as feedstock for biofuel because half of the world's population is unable to afford the food oil as feedstock for fuel production. Looking at the significance of biodiesel and the resources of biofuel, in this paper, a comparative exhaustive study has been reported with for three important plants, namely Jatropha curcas, Pongemia pinnata and Balanites aegyptiaca. These plants were selected based on their biodiesel potential, availability, cultivation practices and general information available. The present study involves scientometric publications, comparison of fatty acid composition and biodiesel parameters. We have also compared climatic conditions for the growth of the plants, economic feasibility of biodiesel production and other ecological services. The study paves a way for sustainable solution to policy makers and foresters looking for selection of plant species as bioenergy resource.

Chromatic intervention and biocompatibility assay for biosurfactant derived from Balanites aegyptiaca (L.) Del.

Extraction of biosurfactants from plants is advantageous than from microbes. The properties and robustness of biosurfactant derived from the mesocarp of Balanites aegyptiaca have been reported. However, the dark brown property of biosurfactant and lack of knowledge of its biocompatibility limits its scope. In the present work, the decolorization protocol for this biosurfactant was optimized using hydrogen peroxide. The hemolytic potential and biocompatibility based on cell toxicity and proliferation were also investigated. This study is the first report on the decolorization and toxicity assay of this biosurfactant. For decolorization of biosurfactant, 34 full factorial design was used, and the data were subjected to ANOVA. Results indicate that 1.5% of hydrogen peroxide can decolorize the biosurfactant most efficiently at 40 °C in 70 min at pH 7. Mitochondrial reductase (MTT) and reactive oxygen species (ROS) assays on M5S mouse skin fibroblast cells revealed that decolorized biosurfactant up to 50 µg/mL for 6 h had no significant toxic effect. Hemolysis assay showed ~ 2.5% hemolysis of human RBCs, indicating the nontoxic effect of this biosurfactant. The present work established a decolorization protocol making the biosurfactant chromatically acceptable. Biocompatibility assays confirm its safer use as observed by experiments on M5S skin fibroblast cells under in vitro conditions.

Screening Balanites aegyptiaca for inhibitors against putative drug targets in Microsporum gypseum - Subtractive proteome, docking and simulation approach.

Microsporum gypseum is a keratinophilic fungi grouped under dermatophytes infecting skin, hair and nail portions in human and animals causing tinea corporis, tinea facei and tinea capitis. As both human and fungi are eukaryotes, the available drugs for treating dermatophytes produce some side effects due to drug interaction with human also. Apart from this, the gut microbiota has a very big role in the health of human which should not be affected by the drugs. Hence this study focused on finding a target which is unique and essential to M. gypseum and non-homologous to human and gut microbiota, non-homologous to human domain architecture, highly interacting with other proteins, sub-cellular localization of proteins and non-druggability analysis of the targets using subtractive proteomics approach which resulted with 3 novel drug targets from M. gypseum which were modeled using I-TASSER, refined by ModRefiner and validated by PROCHECK. Further these targets were docked with compounds identified through LC-MS of fractioned methanol extract of B. aegyptiaca fruit pulp using Glide module and the stability of the docked complex was analyzed by molecular dynamics simulation using Desmond module of Schrodinger. Cyanidin-3-O-rhamnoside had better interaction with all the targets and Taurocholic acid had better result with ECCP which suggests the multi-targeting potency of these two compounds against M. gypseum which has to be confirmed by in vitro and in vivo studies.

Balanites aegyptiaca ameliorates insulin secretion and decreases pancreatic apoptosis in diabetic rats: Role of SAPK/JNK pathway.

SAPK-JNK pathway performs a significant role in the pathogenesis of type 2 diabetes. Balanites aegyptiaca (BA) is used as an anti-diabetic agent in folk medicine however its hypoglycemic mechanism is not fully elucidated. The current study aimed to evaluate the effect of crude extract, butanol, and dichloromethane fractions from BA on the stress-activated protein kinase/c-Jun N-terminal kinase (SAPK-JNK) pathway in experimental diabetic rats. Six groups of male Wistar rats were included: normal control, diabetic, diabetic rats treated with crude, butanol or dichloromethane fraction from BA (50 mg/kg BW) and diabetic rats treated with gliclazide as a reference drug for one month. Our results suggested a protective role of treatment of diabetic rats with BA against oxidative stress-induced SAPK-JNK pathway. Moreover, BA treatment produced a reduction in plasma glucose, HbA1c, lactic acid, lipid profile, malondialdehyde levels and produced an increase in insulin, reduced glutathione levels, catalase and superoxide dismutase activities compared with untreated diabetic rats. Moreover, it decreased apoptosis signal-regulating kinase 1, c-Jun N-terminal kinase 1, protein 53 and increased insulin receptor substrate 1 in rat pancreas while it increased glucose transporter 4 in rat muscle. Analysis of BA extracts by LC-HRMS revealed the presence of different saponins with reported hypoglycemic effect. In conclusion, BA exerted hypoglycemic, hypolipidemic, insulinotropic and antioxidant effects. Additionally, it reduced apoptosis in pancreatic ß-cells and increased glucose uptake in muscle. These results suggest that the hypoglycemic effect of BA is due to the inhibition of the SAPK-JNK pathway.

Anthelmintic effects of indigenous multipurpose fodder tree extracts against Haemonchus contortus.

Condensed tannins (CT) extracted from Balanites aegyptiaca, Tamarindus indica, and Celtis toka browses were used to evaluate their anthelmintic effect on different developmental stages of Haemonchus contortus. To achieve this objective, various serial concentrations of each CT extract of the foliages were used to test adult motility, inhibition of egg hatchability, and larval development. The fodders were selected based on their multipurpose advantage and accessibility to use as fodder for livestock in the low lands of the Gambella region. The fastest and slowest adult motility rate was observed in 2-ml (4 min) and 0.125-ml dose of C. toka, respectively, which is better than that in ivermectin. Egg hatchability inhibition was observed with dose difference within species, but there is no difference between B. aegyptiaca and T. indica. The foliage extracts of the studied browses were observed to inhibit the larvae by 100% at 2 ml, which is similar to ivermectin. There is no significant difference observed in larvae development inhibition between the species and ivermectin (p > 0.05). CT extracts of studied plants have found to own significant anthelmintic activity in a dose-dependent manner. They could serve as anthelmintic economically and eco-friendly after further and series of in vivo experiments.

Induction of Apoptosis in Human Cancer Cells Through Extrinsic and Intrinsic Pathways by Balanites aegyptiaca Furostanol Saponins and Saponin-Coated SilverNanoparticles.

The aim of this investigation is to examine the anticancer activities of Balanites aegyptiaca fruit extract with its biogenic silver nanoparticles (AgNPs) against colon and liver cancer cells. B. aegyptiaca aqueous extract was fractionated according to polarity and by biosynthesized AgNP. The cytotoxicity of the extract, semi-purified fractions, and the AgNPs was examined on noncancerous cell lines. The safer fraction was subjected to ultra-performance liquid chromatography-MS to identify the major active constituents. The anticancer activities of the nontoxic doses of all the used treatments were tested against HepG2 and CaCo2 cells. The nontoxic dose of the B. aegyptiaca (0.63 mg/ml) extract showed high anti-proliferative activities against HepG2 and CaCo2 with a percentage of 81 and 77%, respectively. The butanol fraction was safer than the other two fractions with 46.3 and 90.35% anti-proliferative activity against Caco2 and HepG2 cells, respectively. The nontoxic dose of AgNPs (0.63 mg/ml) inhibits both HepG2 and Caco2 cells with a percentage of 84.5 and 83.4%, respectively. In addition, AgNPs regulate the expression of certain genes with folding higher than that of crude extract. Saponin-coated AgNPs showed great abilities to select the most anticancer ingredient(s) from the B. aegyptiaca extract with a more safety pattern than the polarity gradient fractionation.

Escherichia coli and Staphylococcus aureus. This is the first report of Terminalia chebula for preparation of herbal cleaners.

Chemotherapeutic potentials of the stem bark of Balanite aegyptiaca (L.) Delile: an antiangiogenic, antitumor and antioxidant agent.

BACKGROUND: Balanite aegyptiaca (L.) Delile, is a plant with extensive medicinal properties. Its stem bark is traditionally known for its spasmolytic and antiepileptic properties and used to treat yellow fever, jaundice and syphilis. Angiogenesis (sprouting of new blood vessels) is crucial for tumor growth and metastasis. The goal of this study is investigate the antiangiogenic, cytotoxicity and antioxidant activity as well as antitumor in vivo properties of B. aegyptiaca stem bark extracts. METHOD: The dried powder of stem bark was extracted sequentially with n-hexane, chloroform, methanol and water. Rat aorta ring assay (RARA) was used as a platform to screen for antiangiogenic affect. The most active extract was subjected to further confirmatory antiangiogenic tests i.e. cell migration, tube formation and VEGF inhibition and finally evaluated for its in vivo antitumor efficacy in nude mice. The cytotoxicity of extracts on four cancer cell lines (HCT-116, K562, U937 and MCF-7) and one normal cells line (HUVEC) was evaluated. To assess the antioxidant activity screening, four methods were used, (DPPH•) and ABTS radical scavenging activity, as well as total flavonoids and phenolic contents. RESULTS: Methanol extract of B. aegyptiaca stem bark (MBA) showed the highest antiangiogenic, antioxidant and anticancer properties. It was found selectively cytotoxic to leukemia cell lines as well as breast cancer cell line MCF-7. (MBA) thus exhibited antiangiogenic in ex-vivo rat aorta ring model; it was found to excel its antiangiogenic effect via inhibition of the key growth factor (VEGF) as well as to halt HUVEC cell migration and tube formation, furthermore animals bearing colon cancer treated with (MBA) showed significant reduction in tumor growth. CONCLUSION: Different extracts of B. aegyptiaca stem bark showed various anticancer and antiangiogenic properties. MBA demonstrated potent antiangiogenic, antioxidant and antitumor in vivo. The outcome of this study suggests the potential of stem bark of the B. aegyptiaca for developing chemotherapeutic agent against solid tumor as well as leukemia.

Antidiabetic and Antioxidant Impacts of Desert Date (Balanites aegyptiaca) and Parsley (Petroselinum sativum) Aqueous Extracts: Lessons from Experimental Rats.

Medicinal plants are effective in controlling plasma glucose level with minimal side effects and are commonly used in developing countries as an alternative therapy for the treatment of type 1 diabetes mellitus. The aim of this study is to evaluate the potential antidiabetic and antioxidant impacts of Balanites aegyptiaca and Petroselinum sativum extracts on streptozotocin-induced diabetic and normal rats. The influences of these extracts on body weight, plasma glucose, insulin, total antioxidant capacity (TAC), malondialdehyde (MDA) levels, and liver-pyruvate kinase (L-PK) levels were assessed. Furthermore, the weight and histomorphological changes of the pancreas were studied in the different experimental groups. The herbal preparations significantly reduced the mean plasma glucose and MDA levels and significantly increased the mean plasma insulin, L-PK, and TAC levels in the treated diabetic groups compared to the diabetic control group. An obvious increase in the weight of the pancreas and the size of the islets of Langerhans and improvement in the histoarchitecture were evident in the treated groups compared to untreated ones. In conclusion, the present study provides a scientific evidence for the traditional use of these extracts as antidiabetic and antioxidant agents in type 1 diabetes mellitus.

Management of Hyperglycaemia by Ethyl Acetate Extract of Balanites aegyptiaca (Desert Date).

Reactive oxygen species play a significant role in the pathogenesis of retinopathy in diabetes patients. The current study aimed to assess the effect of ethyl acetate extract (EAE) from Balanites aegyptiaca (10, 25 or 50 mg/kg b.w.) in experimental diabetic rats. To achieve this aim, five groups of male rats were included: control, diabetic, and diabetic rats treated with 10, 25, and 50 µg/kg b.w. of EAE for eight weeks. Our results suggests a protective role of EAE against oxidative stress induced by streptozocine. EAE treatment produced a reduction in blood glucose levels, HbA1c, malondialdehyde and vascular endothelial growth factor (VEGF) in diabetic retina (p < 0.001), as well as an enhancement in antioxidant capacity against streptozocine-induced oxidative stress. Tumor necrosis factor alpha (TNF-α), interleukin (IL-1ß) and vascular endothelial growth factor (VEGF) were significantly reduced in diabetic rats treated with EAE, compared with untreated diabetic rats. Analysis of EAE by GC-MS indicated the presence of ß-sistosterol. Overall, EAE modulates oxidative stress induced by streptozocine and enhances antioxidant activity, which may provide additional endothelial protection in retina of diabetic rats. These results hold great promise in the management of diabetic complications.

Unraveling the active hypoglycemic agent trigonelline in Balanites aegyptiaca date fruit using metabolite fingerprinting by NMR.

Trigonelline (3-carboxy-1-methyl pyridinium) was identified as a relevant bioactivity and taste imparting component in Balanites aegyptiaca fruit, using (1)H NMR of crude extracts without any fractionation or isolation step. The structural integrity of trigonelline was established within the extract matrix via(1)H NMR, (1)H-(1)H COSY, HMQC and HMBC and by comparison with authentic standard. A quantitative (1)H NMR method (qHNMR) was used to determine trigonelline concentrations in the peel and pulp of B. aegyptiaca fruit of 8 and 13mgg(-1), respectively. Trigonelline so far has not been reported from B. aegyptiaca or its genus as it easily escapes LC-MS based detection. Its discovery provides novel insight into the balanite fruits antidiabetic properties as the compound is known for a pronounced hypoglycemic effect. In addition, it is likely to impart the perceptible bitter taste portion to balanites sweet bitter taste. UPLC-MS of the crude extract additionally revealed the fruit flavonoid pattern showing quercetin/isorhamnetin flavonol conjugates in addition to epicatechin, the latter being present at much lower levels.

Aldose reductase inhibition of a saponin-rich fraction and new furostanol saponin derivatives from Balanites aegyptiaca.

BACKGROUND: Balanites aegyptiaca Del. (Zygophyllaceae) fruits are used to treat hyperglycemia in Egyptian folk medicine and are sold by herbalists in the Egyptian open market for this purpose. Nevertheless, the fruits have not yet been incorporated into pharmaceutical dosage forms. The identity of the bioactive compounds and their possible mechanisms of action were not well understood until now. PURPOSE: Aldose reductase inhibitors are considered vital therapeutic and preventive agents to address complications caused by hyperglycemia. The present study was carried out to identify the primary compounds responsible for the aldose reductase inhibitory activity of Balanites aegyptiaca fruits. STUDY DESIGN: The 70% ethanolic extract of Balanites aegyptiaca fruit mesocarp and its fractions were screened for inhibition of the aldose reductase enzyme. Bio-guided fractionation of the active butanol fraction was performed and the primary compounds present in the saponin-rich fraction (D), which were responsible for the inhibitory activity, were characterized. HPLC chromatographic profiles were established for the different fractions, using the isolated compounds as biomarkers. METHODS: Aldose reductase inhibition was tested in vitro on rat liver homogenate. The butanol fraction of the 70% ethanolic extract was fractionated using vacuum liquid chromatography (VLC, RP-18 column). The most active sub-fraction D, which was eluted with 75% methanol, was subjected to preparative HPLC to isolate the bioactive compounds. RESULTS: The butanol fraction displayed inhibitory activity against the aldose reductase enzyme (IC50 = 55.0 ± 6 µg/ml). Sub-fraction D exhibited the highest inhibitory activity (IC50 = 12.8 ± 1 µg/ml). Five new steroidal saponin derivatives were isolated from this fraction. The isolated compounds were identified as compound 1a/b, a 7:3 mixture of the 25R:25S epimers of 26-O-ß-D-glucopyranosyl-furost-5-ene-3,22,26-triol 3-O-[α-L-rhamnopyranosyl-(1→3)- ß-D-glucopyranosyl-(1→2)]- α-L-rhamnopyranosyl-(1→4)-ß-D-glucopyranoside; compound 2, 26-O-ß-D-glucopyranosyl-(25R)-furost-5-ene-3,22,26-triol 3-O-[ ß-D-glucopyranosyl-(1→2)]- α-L-rhamnopyranosyl-(1→4)-ß-D-glucopyranoside; compound 3, 26-O-ß-D-glucopyranosyl-(25R)-furost-5,20-diene-3,26-diol 3-O-[α-L-rhamnopyranosyl-(1→3)- ß-D-glucopyranosyl-(1→2)]- α-L-rhamnopyranosyl-(1→4)-ß-D-glucopyranoside; compound 4, 26-O-ß-D-glucopyranosyl-(25R)-furost-5,20-diene-3,26-diol 3-O-[ ß-D-glucopyranosyl-(1→2)]- α-L-rhamnopyranosyl-(1→4)-ß-D-glucopyranoside; and compound 5, which is the 25S epimer of compound 4, by using various spectroscopic methods [MS,1D and 2D NMR (HSQC, HMBC, DQF-COSY, HSQC-TOCSY)]. Compounds 1a/b, 2, 3, 4, 5 exhibited highly significant aldose reductase inhibitory activities (IC50 values were 1.9 ± 0.2, 1.3 ± 0.5, 5.6 ± 0.2, 5.1 ± 0.4, 5.1 ± 0.6 µM, respectively) as compared to the activity of the reference standard quercetin (IC50 = 6.6 ± 0.3 µM). CONCLUSION: The aldose reductase inhibitory activity of Balanites fruits is due to the steroidal saponins present. HPLC chromatographic profiles of the crude butanol fraction and its 4 sub-fractions showed that the most highly bioactive fraction D contained the highest amount of steroidal saponins (75%) as compared to the 21% present in the original butanol fraction. The isolated furostanol saponins proved to be highly active in an in vitro assay.

Effect of Balanites aegyptiaca on Ehrlich Ascitic carcinoma growth and metastasis in Swiss mice.

The role of Balanites aegyptiaca (B. aegyptiaca) on development and growth of Ehrlich Ascitic carcinoma (EAC) and metastasis (liver and spleen) was evaluated. Balanite (400mg/kg; 10mg in 0.1ml/mouse) was given daily over a period of two weeks started 24h before intraperitoneal injection of EAC (2×10(6)/once). The present study deals with the effect of B. aegyptiaca on the growth of transplantable ascetic tumor, life span of EAC-bearing mice, hepatocellular and splenic histology. Antioxidant and biochemical changes as well as p53 genes expression were recorded. B. aegyptiaca extracts inhibited tumor growth and proliferation in ascetic fluid through a significant decrease in tumor volume, total cell volume, and viable cell count and prolonged the life span of mice. Also, it significantly decreased the levels of lipid peroxidation and increased SOD, CAT levels and P53 expression. Also, balanite inhibited either tumor invaded/or affected hepatic and splenic tissue. This result gives a new insight on beneficial effect of B. aegyptiaca in primary and secondary loci of Ehrlich Ascitic tumor through its antioxidant effect.

Laboratory assessment of the molluscicidal and cercariacidal activities of Balanites aegyptiaca.

OBJECTIVE: To assess the molluscicidal and cercariacidal activities of aqueous extracts of Balanites aegyptiaca (B. aegyptiaca) against Ethiopian Biomphalaria pfeifferi (B. pfeifferi), Lymnaea natalensis (L. natalensis) and Schistosoma mansoni (S. mansoni) cercariae. METHODS: Extracts of seeds, endocarp, mesocarp, and fruit of B. aegyptiaca were tested for their activities against adult B. pfeifferi and L. natalensis. The cercariacidal activity of the seeds of the plant was also evaluated against S. mansoni. Bioassays were carried out following the methods recommended by WHO. Snail mortalities were compared between each plant part and snail species, and LC50 and LC90 values for the plant parts tested were computed. The cercariacidal activity of the plant was assessed by exposing the mice to the cercariae pre-exposed to aqueous extract of B. aegyptiaca seeds. RESULTS: For the molluscicidal activities of seeds, endocarp, mesocarp and whole fruit, the LC50 values against B. pfeifferi were 56.32, 77.53, 65.51 and 66.63 mg/L, respectively, while the respective LC90 values were 77.70, 120.04, 89.50 and 97.55 mg/L. Similarly, the LC50 values for the seeds, endocarp, mesocarp and whole fruit against L. natalensis were 80.33, 92.61, 83.52 and 87.84 mg/L, respectively, while the respective LC90 values were 102.30, 138.21, 115.42 and 127.69 mg/L. B. pfeifferi were found to be more susceptible to B. aegyptiaca than L. natalensis. S. mansoni cercariae exposed to 15 mg/L of extract of seeds were incapable of infecting mice. The mean egg load of tissue was reduced in mice infected with the cercariae exposed to 5 and 10 mg/L of the extract. CONCLUSIONS: The aqueous extracts of different parts of B. aegyptiaca exhibited reasonable molluscicidal activity against B. pfeifferi and L. natalensis, as well as cercariacidal activity against S. mansoni cercariae. However, comprehensive laboratory evaluation is recommended prior to field tests of the plant parts since their impact on other aquatic biota is not known.

FTIR and DSC studies of the thermal and photochemical stability of Balanites aegyptiaca oil (Toogga oil).

The oil extracted from the bean of Balanites aegyptiaca was characterized, and its photochemical and thermal stabilization were evaluated. The chemical composition was determined using gas chromatography (GC), revealing that the oil is very rich in unsaturated fatty acids (72% omega-6 and omega-9). The photochemical stability was assessed by subjecting it to artificially accelerated photo-aging and then examining the changes using infrared spectroscopy. The thermal stability was studied at six different temperatures ranging from 130 to 200°C and monitored in situ by differential scanning calorimetry (DSC). The kinetic parameters (EA and k) describing the thermal degradation of this oil were calculated. It has been shown that the antioxidants present in the oil delay the oxidation process (induction period). The degradation of the Toogga oil was compared with that of oleic and linoleic fatty acids. In addition, the degradation of the Toogga oil extracted with hexane was compared to that of the neat oil.

Molluscicidal activity of Balanites aegyptiaca against Monacha cartusiana.

CONTEXT: Balanites aegyptiaca (L.) Delile (Zygophyllaceae) is a tropical tree that has many folk uses in various countries. The bark extract is used for the control of the fresh water snails that act as intermediary host of Schistosoma. OBJECTIVE: Study the molluscicidal activity and chemical constituents of seed oil and seed glycosides of B. aegyptiaca against Monacha cartusiana and determine the structure-activity relationship. MATERIALS AND METHODS: Two bioassay methods (residual film application and the leaf dipping technique) were used to evaluate the toxicity effect of the seed oil and glycosides, in concentrations of 1.000, 0.500, 0.250 and 0.125%. The seed oil was analysed by GC/MS. Acid hydrolysis and chromatographic separation were used to study the seed saponins. RESULTS: The bioassay of B. aegyptiaca against the land snail, M. cartusiana, indicated the activity of the seed oil and the high activity of the seed saponins. The seed glycosides gave 30.0, 53.3, 73.0 and 73.3% mortality for concentrations of 0.125, 0.250, 0.500 and 1.00%, respectively. The LC(50) values were 0.335 and 0.256%, respectively. The seed oil was analysed by GC/MS. Acid hydrolysis of the seed saponins gave a mixture of diosgenin, yamogenin and 3,5-spirostadiene. DISCUSSION AND CONCLUSION: To study the structure-activity relationship, a triterpenoidal saponin and a triterpenoidal saponins rich extract (of Zygophyllum coccenum) were proven to be inactive. Thus, the activity is associated with the steroidal, not triterpenoidal saponins. Moreover, a spirostane aglycone without sugar moiety, was found to be inactive and attained the activity by glycosidation.
