RESUMO

The genus Carthamus Linnaeus, which belongs to the tribe Cardueae in the Asteraceae family, originated in the Mediterranean region and consists of approximately 20 species worldwide. Understanding the phylogeny of the Carthamus is crucial for the cultivation of C. tinctorius. Although chloroplast genomes are widely used for species identification and evolutionary studies, there have been limited investigations on the chloroplast genomes of Carthamus species. In this study, we assembled the chloroplast genomes of C. persicus, C. tinctorius × C. persicus, and C. lanatus and combined them with the five chloroplast genomes of C. tinctorius for comparative genomic analysis. The sizes of the chloroplast genomes of C. lanatus, C. persicus, and C. tinctorius × C. persicus were 152,602 bp, 153,177 bp, and 153,177 bp, respectively. Comparative analysis showed that the chloroplast genome structures of the four Carthamus species were highly conserved. Additionally, the phylogenomic analysis demonstrated that the plastid genome and angiosperms353 dataset significantly improved the phylogenetic support of Carthamus species. This analysis supported Carthamus as a monophyletic taxon and its internal division into the sect. Carthamus and sect. Atractylis. The Carthamus was closely related to Carduncellus, Femeniasia, Phonus, and Centaurea. In conclusion, this study not only expands our understanding of the cp genomes of Carthamus species but also provides support for more comprehensive phylogenetic studies of Carthamus.

RESUMO

The impacts of Ni toxicity on growth behaviors, photochemical, and antioxidant enzymes activities of wild (Carthamus oxyacantha M. Bieb.) and cultivated (Carthamus tinctorius L.) safflower species were investigated in this study. Fourteen-day-old seedlings were treated with excessive Ni levels [control, 0.5, 0.75, and 1.0 mM NiCl2·6H2O] for 7 days. The results of chlorophyll a fluorescence indicated that toxic nickel exposure led to changes in specific, phenomenological energy fluxes and quantum yields in thylakoid membranes, and activities of donor and acceptor sides of photosystems. These changes resulted in a significant decrease in the photosynthetic activities by about 50% in both species, but these negative effects of Ni were not in a level to destroy the functionality of the photosystems. At the same time, toxic Ni affected membrane integrity and the amount of photosynthetic pigments in the antenna and active reaction centers. Additionally, the accumulation of Ni was higher in roots than in stem and leaves for both species. Depending on Ni accumulation, a significant reduction in dry biomass of root by approx. 64.8 and 45.7% and shoot by 41 and 24.7% were observed in wild and cultivated species, respectively. Two species could probably withstand deleterious Ni toxicity with better upregulating own protective defense systems such as antioxidant enzymes and phenolic compounds. Among of them, SOD and POD activities were increased with increasing Ni concentrations. The POD activities of both species were most prominent and consistently increased (approx. 2 folds in roots and 6 folds in leaves) in highly toxic Ni levels and may be protected them from damaging effect of H2O2. When all results are evaluated as a whole, Carthamus species produced similar responses to toxicity and also both species have bioconcentration (BCF) and bioaccumulation factor (BF) > 1 and translocation factor < 1 under Ni toxicity may be regarded a good indication of Ni tolerance. Furthermore, it is possible to use the Carthamus species as phytostabilizers of soils contaminated with nickel, because of their roots accumulating more nickel.

RESUMO

Abstract ROS (Reactive Oxygen Species) production is a usual plant reaction to environmental stresses such as allelopathy. Plants possess antioxidant enzymes to scavenge cells and resist against the ROS. This study was conducted to evaluate changes in antioxidant enzymes (CAT, GPX, APX) in radish seedlings in response to allelopathic effect of safflower root and shoot residues grown under normal irrigation and drought stress. Safflower allelopathic effect led to an increase in antioxidant enzymes activities. GPX activity increased more than CAT and APX. Radish seedlings exposed to safflower residue grown under drought stress showed more antioxidant enzymes activities. Root residues enhanced the activities of antioxidant enzymes greater than shoot. Seedlings exposed to root residues grown under drought stress had the highest level of antioxidant enzymes activities.

RESUMO

AIM AND OBJECTIVE: Nowadays, developing effective antibiotics for bacterial control has become difficult due to increased resistance to the available medicines in the market. Essential oils possess interesting biological properties as some of their components have very powerful antiviral and antibacterial properties. Carthamus caeruleus is a plant that has antibacterial and antioxidant activity due to the presence of an acetylenic compound, Carlina oxide. The aim of this work was to provide, for the first time, the chemical modifications to the structure of Carlina oxide and the insilico study of these analogues. MATERIALS AND METHODS: The essential oil of Carthamus caeruleus was extracted by steam distillation in a Clevenger-type apparatus. Carlina oxide component was separated by column chromatography. Five new analogues were synthetized and identified by spectroscopic analyses (RMN, IR and SM). Molecular docking simulation study was performed using Molecular Operating Environment software (MOE) on three enzymes of bacterial origin (Streptococcus pyogenesis and Enterococcus faecalis). RESULTS: Five new compounds derived from Carlina oxide were synthesized (IM8-IM12), and their structures were characterized by infrared (IR), 1H and 13C nuclear magnetic resonance (NMR). The new synthesized compounds were evaluated as mSpeB, DHFR from Enterococcus faecalis and DNA gyrase inhibitors by a docking analysis using MOE. These results show interesting ligand interactions with the three enzymes, and the best result was attributed to the complexes formed with IM9, which had the lowest score. CONCLUSION: In fact, these new compounds could lead to powerful approaches for the research and development of new antibiotics.

RESUMO

AIM AND OBJECTIVE: Oxidative stress is implicated in the development and progression of many diseases. Some of the appropriate actions that could taken to resolve the problem of these diseases are search for new antioxidant substances isolated from plants. The aims of this study were to research the intraspecies variations of A. verticillata and C. caeruleus essential oils from 8 locations using statistical analysis, the in vitro antioxidant properties of collective essential oils and in combinations. MATERIALS AND METHODS: The essential oils were analyzed by GC and GC-MS. The intraspecies variations of the essential oil compositions were discussed using principal component analysis (PCA) and cluster analysis (CA). The antioxidant properties were evaluated DPPH-radical scavenging activity and ß-carotene bleaching test. RESULTS: The main components of Ammoides verticillata collective essential oil (Coll EO) were thymol (30.5%), carvacrol (23.2%), p-cymene (13.1%), limonene (12.5%) and terpinene-4-ol (12.3%). While roots of Carthamus caeruleus essential oil were dominated by carline oxide (86.2%). The chemical variability allowed the discrimination of two main Groups for both Coll EOs. A direct correlation between the altitudes, climate and the chemical compositions was evidenced. Ammoides verticulata and Carthamus caeruleus Coll Eos showed good antioxidant activity. In binary mixture, the interaction between both Coll Eos and between oils rich of thymol and/or carvacrol with carlina oxide produced the best synergistic effects compared to individual essential oils and the synthetic antioxidant (BHT). CONCLUSION: Ammoides verticillata and Carthamus caeruleus essential oil blends can be used as a natural food preservative and alternative to chemical antioxidants.

RESUMO

Anatomical study of leaf xylary vessel elements of Carthamus oxycantha under various intensities of lead (Pb) and nickel (Ni) stress (200, 400, 600, and 800 mg Pb(NO3 )2 , NiCl2 ·6H2 O/kg of the soil) was conducted. The deformations caused due to metal stress were detected using point-based image registration technique. Initially, a set of corresponding feature points called landmarks was selected for warping of two-dimensional microscopic images of deformed/source vessel (stressed) to its normal/target (unstressed) counterpart. The results show that the target registration error is less than 3 mm using real plant image datasets. The stress caused alterations mainly in diameter, size, and shape of the cells. Average cell diameter and average wall diameter of vessels were measured with "Image J." The range of decrease in average cell diameter from 18.566 to 13.1 µm and the range of increase in average wall diameter was from 5.166 to 10.1 µm, with increase in stress factor through 200, 400, 600, and 800 mg Pb(NO3 )2 , NiCl2 ·6H2 O/kg of the soil. We noted large deformation in the form of shrinkage in cell size and diminution in its diameter. The diminution in diameter and the shrinkage in cell size of vessel cells may be due to the deposition of wall materials. It can be a possible strategy to limit the water flow to overcome the rapid mobility and transportation of the excess amount of metals to safeguard the cellular components from unpleasant consequences of metallic stress.

RESUMO

BACKGROUND: Plant-based drugs provide an outstanding contribution to modern therapeutics, and it is well known that the presence of different phytochemicals is responsible for such pharmacological effects. Carthamus tinctorius L. is one such medicinally important plant whose different solvent extracts have been reported with several pharmacological effects like antibacterial, hepatoprotective, and wound healing. The exploration of phytoconstituents from such a medicinally important plant for different pharmacological effects could produce new and effective drugs to treat human diseases. OBJECTIVE: The present study attempts to explore the antibacterial and anthelmintic properties of dehydroabietylamine, a diterpene isolated from Carthamus tinctorius L. followed by the in silico elucidation of its probable mode of action. METHODS: The minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) of dehydroabietylamine were assessed against Staphylococcus aureus and Pseudomonas aeruginosa, using micro- broth dilution method. The anthelmintic activity of was determined to assess the time taken for paralysis and death of Pheretima Posthuma at different concentrations. Additionally, molecular docking study was conducted to understand the interaction between dehydroabietylamine with target proteins identified for both antibacterial and anthelmintic activity viz., glucosamine-6-phosphate synthase and ß-Tubulin, respectively. RESULTS: The dehydroabietylamine showed the significant MIC for S. aureus (12.5 µg/ml) and P. aeruginosa (6.25µg/ml), respectively. The result of anthelmintics effect of dehydroabietylamine was found to be dosedependent and compared to the standard drug, albendazole. CONCLUSION: The interactions of dehydroabietylamine with the two target proteins with high binding affinity indicated the probable inhibition of target proteins, which could be the cause for prominent antibacterial and antihelminthic effects.

RESUMO

The Mediterranean diet is considered to prevent several diseases. In the present study, the antioxidant properties of six extracts from Mediterranean plant foods were assessed. The extracts' chemical composition analysis showed that the total polyphenolic content ranged from 56 to 408 GAE mg/g dw of extract. The major polyphenols identified in the extracts were quercetin, luteolin, caftaric acid, caffeoylquinic acid isomers, and cichoric acid. The extracts showed in vitro high scavenging potency against ABTS•+ and O2 •- radicals and reducing power activity. Also, the extracts inhibited peroxyl radical-induced cleavage of DNA plasmids. The three most potent extracts, Cichorium intybus, Carthamus lanatus, and Cichorium spinosum, inhibited OH•-induced mutations in Salmonella typhimurium TA102 cells. Moreover, C. intybus, C. lanatus, and C. spinosum extracts increased the antioxidant molecule glutathione (GSH) by 33.4, 21.5, and 10.5% at 50 µg/ml, respectively, in human endothelial EA.hy926 cells. C. intybus extract was also shown to induce in endothelial cells the transcriptional expression of Nrf2 (the major transcription factor of antioxidant genes), as well as of antioxidant genes GCLC, GSR, NQO1, and HMOX1. In conclusion, the results suggested that extracts from edible plants may prevent diseases associated especially with endothelium damage.

RESUMO

OBJECTIVES: The roots of Carthamus caeruleus have been used by the population of Northern Algeria to treat several pathological conditions, including wound healing and hair growth. The present study was conducted to evaluate the anti-inflammatory activity, wound-healing potential, and hair growth-promoting activity attributed to C. caeruleus root. MATERIALS AND METHODS: In this study, we have investigated the anti-inflammatory effect using carrageenan-induced paw edema test, evaluated the wound-healing potential by linear incision wound model, and evaluated hair growth activity using in vivo hair growth-promoting test attributed to C. caeruleus root. Preliminary phytochemical screening and gas chromatography coupled to mass spectrometry (GC/MS) characterization were also performed. RESULTS: It was found that the methanolic extract of C. caeruleus was characterized by the presence of tannins, flavonoids, anthocyanins, leucoanthocyanins, sennosides, free quinones, saponins, glycosides, mucilage, and coumarins. The GC/MS analysis could identify 22 compounds and showed that the major chemical constituents were palmitic acid (12.88%), mono(2-ethylhexyl) phthalate (12.75%), and 5-(hydroxymethyl)-2-furancarboxaldehyde, (9.19%). The phytoextract strongly inhibited (P < 0.001) paw edema formation in mice. The roots of C. caeruleus also showed a significant (P < 0.05) wound-healing and hair growth-promoting effects. CONCLUSION: The results indicate the richness of the roots of the Algerian C. caeruleus in biomolecules. These molecules exhibit an excellent reducing inflammation activity, a wound-healing property, and an interesting hair-promoting growth activity. All in all, the findings promote the usage of the Algerian C. caeruleus as an effective and a safe potential skincare alternative remedy.

RESUMO

This experiment was conducted to assess genetic relationships among safflower genotypes from different geographical regions of Iran and other countries using newly developed simple sequence repeat (SSR) markers. By enrichment method, 32 primer pairs were designed of which 18 pairs were able to detect polymorphism in 105 safflower cultivars from Carthamus tinctorius, C. oxyacanthus, C. lanatus, C. glaucus, C. boissieri and C. dentatus. The selected SSR primers amplified a total of 59 alleles with an average of 3.27 alleles per locus among the cultivars and the average values of gene diversity, heterozygosity and PIC were 0.45, 0.37 and 0.39, respectively. Neighbour-joining cluster analysis based on Nei's genetic distance categorized populations of Carthamus in six major clusters; all wild accessions were grouped differently from cultivated genotypes. Cluster analysis significantly distinguished C. oxyacanthus genotypes in different categories: centre (Arak), northeast (Azarbaiejan), east (Kermanshah) and southeast (Shiraz, Chaharmahal and Kohgiluyeh). The presence of C. boissieri and C. glaucus in one cluster appeared to be in close relationship between each other, indicating a common ancestor. The results revealed that C. dentatus discriminated from the species with n = 10 chromosomes, C. boissieri and C. glaucus assigned in to separate subsection. In summary, this study has shown that domesticated and wild genotypes were clustered into two major groups indicating these markers as appropriate tools to amassment genetic diversity and genome mapping.

RESUMO

Traditional Chinese medicine (TCM)-based herbal therapies have gained increasing popularity worldwide, raising concerns of its efficacy, safety profile and potential interactions with Western medications. Antithrombotic agents are among the most common prescription drugs involved in herb-drug interactions, and this article focused on aspirin, one of the most widely used antiplatelet agents worldwide. We discussed herbs that have potential interactions by exploring Western and TCM approaches to thrombotic events. Common TCM indications for these herbs were also highlighted, including possible scenarios of their concurrent usage with aspirin. With greater awareness and understanding of potential herb-drug interactions, TCM and Western physicians may collaborate more closely to identify, treat and, most importantly, prevent adverse drug events.

RESUMO

Total flavonoid content (TFC) and cyanidin-3-glucoside (Cyd-3-glu) of seed and seed coat extract of 16 genotypes from five species of Carthamus were studied, and their major polyphenolic compounds and antioxidant activity of the seed coat extracts were determined using HPLC analysis and DPPH assay, respectively. Additionally, fatty acids composition of the seed oil was analyzed by GC. In general, TFC and Cyd-3-glu content of seed coat extracts were higher than those of seed extracts. A novel breeding line with black seed coat (named A82) depicted lower TFC (3.79 mg QUE/g DW) but higher Cyd-3-glu (24.64 mg/g DW) compared to the white and other seed-pigmented genotypes. DPPH radical scavenging activity showed a strong association with Cyd-3-glu content (r = 0.84), but no correlation with TFC (r = -0.32). HPLC analysis of seed coat extracts revealed that four compounds were dominant constituents including rutin (7.23 - 117.95 mg/100 g DW), apigenin (4.37 - 64.88 mg/100 g DW), quercetin (3.09 - 14.10 mg/100 g DW), and ferulic acid (4.49 - 30.41 mg/100 g DW). Interestingly, the genotype A82 with an appropriate polyunsaturated/saturated fatty acids index (5.46%) and a moderate linoleic fatty acid content (64.70%) had higher nutritional and pharmaceutical value than all the other genotypes.

RESUMO

Inhibition of α-glucosidase has attracted the attention of researchers due to its connection to type-2 diabetes. Hydroxysafflor yellow A (HSYA) extracted from Carthamus tinctorius L. is a natural antioxidant used in traditional Chinese medicine. In this study, the effect of HSYA on α-glucosidase was evaluated using inhibitory kinetics based on the antioxidant properties of HSYA and by performing computational simulation integration methods. HSYA reversibly inhibited α-glucosidase in a competitive inhibition manner and the evaluated kinetic parameters were IC50 = 1.1 ± 0.22 mM and Ki = 1.04 ± 0.23 mM, respectively. The results of spectrofluorimetry showed that the inner hydrophobic regions of α-glucosidase, which are mostly in the active site, were exposed to the surface with increasing HSYA concentrations, indicating that the inactivation of α-glucosidase by HSYA was accompanied by regional unfolding. The molecular dynamics simulations indicated that the four rings of HSYA interact with four residues such as G217, A278, H279, and G280 at the entrance of the active site. Our study provides insight into the inhibition of α-glucosidase and the accompanying structural changes by HSYA. Based on its α-glucosidase-inhibiting effect and its potential as a natural antioxidant, HSYA is a potential agent for treating α-glucosidase-associated type-2 diabetes.

RESUMO

Myocardial ischemia damages cardiac myocytes in part via opening of the mitochondrial permeability transition pore. Preventing this pore's opening is therefore a useful therapeutic goal in treating cardiovascular disease. Hydroxysafflor yellow A has been proposed as a nontoxic alternative to other agents that modulate mitochondrial permeability transition pore opening. In this study, we proposed that hydroxysafflor yellow A prevents mitochondrial permeability transition pore formation in anoxic cardiac myocytes, and thus protects the cell from damage seen during reoxygenation of the cardiac myocytes. Experiments with hydroxysafflor yellow A transport in aerobic myocytes show that roughly 50% of the extracellular dye concentration crosses the cell membrane in a 2-h incubation. In our anoxia/reoxygenation protocol, hydroxysafflor yellow A modulated both the reduction of viability and the loss of rod-shaped cells that attend anoxia and reoxygenation. Hydroxysafflor yellow A's protective effect was similar to that of cyclosporin A, an agent known to inhibit mitochondrial permeability transition pore opening. In additional experiments, plated myocytes were loaded with calcein/MitoTracker Red, then examined for intracellular dye distribution/morphology after anoxia/reoxygenation. Hydroxysafflor yellow A-containing cells showed a cardioprotective pattern similar to that of cyclosporin A (an agent known to close the mitochondrial permeability transition pore). We conclude that hydroxysafflor yellow A can enter the cardiac myocyte and is able to modulate anoxia/reoxygenation-induced damage by interacting with the mitochondrial permeability transition pore.

Antithrombotic agents are among the most common prescription drugs involved in herb-drug interactions, and this article focused on aspirin, one of the most widely used antiplatelet agents worldwide. We discussed herbs that have potential interactions by exploring Western and TCM approaches to thrombotic events. Common TCM indications for these herbs were also highlighted, including possible scenarios of their concurrent usage with aspirin. With greater awareness and understanding of potential herb-drug interactions, TCM and Western physicians may collaborate more closely to identify, treat and, most importantly, prevent adverse drug events.

RESUMO

Fundamentos: O excesso de peso vem sendo considerado um importante problema de saúde pública. Na tentativa de reverter esse quadro, são propostos diversos tipos de tratamento. O óleo de cártamo ( Carthamus tinctorius ) vem sendo utilizado na prevenção/tratamento da obesidade. Objetivos: O objetivo deste trabalho foi avaliar os efeitos terapêuticos desse óleo em um modelo experimental de síndrome metabólica. Métodos: Inicialmente foram utilizados ratos Wistar alimentados com dieta altamente palatável (AP) por dez semanas. Após, os animais receberam a dieta AP com suplementação de óleo de soja (APOS) ou óleo de cártamo (APOC), na dosagem 1,0 ml/1000 g de peso do animal. No final do experimento, a composição corporal, o perfil lipídico e glicemia dos animais foram avaliados. Para a análise estatística, utilizou-se o teste t de Student. Resultados: Na primeira fase (indução da síndrome metabólica), os animais que receberam a dieta AP mostraram ganho de peso (p < 0,001), adiposidade visceral (p = 0,001), glicemia (p = 0,001) e triglicerídeos séricos (p = 0,03) significativamente mais elevados do que aqueles do grupo controle. Além disso, houve uma diferença no peso do fígado (p = 0,01). Esses resultados demonstram que a administração de dieta AP é um modelo eficaz para o estudo experimental da síndrome metabólica. Na segunda etapa, os animais do grupo APOC mostraram aumento de colesterol total (p < 0,05) e de LDL-colesterol (p < 0,001). Conclusão: Sob as condições experimentais referidas, conclui-se que a utilização de óleo de cártamo pode causar efeitos deletérios sobre o perfil lipídico em um modelo experimental de síndrome metabólica


Background: Overweight has been considered an important public health problem. To reverse this situation, various types of treatment are proposed. The safflower oil (Carthamus tinctorius L.) has been used in the prevention/treatment of obesity. Objectives: The aim of this study was to evaluate the therapeutic effects of this oil in an experimental model of metabolic syndrome. Methods: Male Wistar rats initially received a highly palatable (HP) diet for ten weeks for validation of a metabolic syndrome model. Following confirmation, the animals were treated with a HP diet and soybean oil (HPSO) or safflower oil (HPSA) supplementation (1.0 mL/1000 g of animal weight). At the end of the experiment, the body composition, lipid profile and blood glucose levels of the animals were assessed. Student t test was used for statistical analysis. Results: In the first stage (induction of metabolic syndrome), the animals given the HP diet showed gain weight (p < 0.001), visceral adiposity (p = 0.001), and significantly higher levels of blood glucose (p = 0.001) and triglycerides (p = 0.03) than those of the control group. Also, there was a difference in liver weight (p = 0.01). These results demonstrate that the HP diet administration is an effective model for the experimental metabolic syndrome study. In the second stage, the animals of the HPSA group showed increased total cholesterol (p < 0.05) and LDL-cholesterol (p < 0.001) levels. Conclusion: Under the referred experimental conditions, the use of safflower oil can cause possible deleterious effects on the lipid profile in a metabolic syndrome experimental model

RESUMO

In this study, formulas containing Salviae Miltiorrhizae Radix et Rhizoma-Carthami Flos in the database of Dictionary of Chinese Medicine Prescription (DCMP) were extracted by using traditional Chinese medicine inheritance support system (TCMISS). The drugs pairs and formula composition rules were analyzed with data mining methods, such as association rules, improved mutual information method and complex system entropy clustering. Totally 39 formulas were included in this study and involved 280 Chinese medicines. The top 5 Chinese medicines most frequently used were Danggui (Angelica sinensis), Chuanxiong (Ligusticum chuanxiong), Xiangfu (Cyperi Rhizoma), Baishao(Radix Paeoniae Alba), Taoren(Prunus persica) and Shengdihuang (Radix Rehmanniae Recens). Six core medicinal pairs were obtained through clustering analysis, namely Danshen (Salviae Miltiorrhizae Radix et Rhizoma)-Xiangfu (Cyperi Rhizoma)-Honghua (Carthami Flos), Danshen (Salviae Miltiorrhizae Radix et Rhizoma)-Baishao (Radix Paeoniae Alba)-Honghua (Carthami Flos), Danshen (Salviae Miltiorrhizae Radix et Rhizoma)-Danggui (A. sinensis)-Xiagnfu (Cyperi Rhizoma)-Honghua (Carthami Flos), Danshen (Salviae Miltiorrhizae Radix et Rhizoma)-Danggui (A. sinensis)-Baishao (Radix Paeoniae Alba)-Honghua (Carthami Flos), Honghua (Carthami Flos)-Danshen (Salviae Miltiorrhizae Radix et Rhizoma)-Baishao (Radix Paeoniae Alba)-Danggui (A. sinensis), Danshen (Salviae Miltiorrhizae Radix et Rhizoma)-Baishao (Radix Paeoniae Alba)-Honghua (Carthami Flos)-Danggui (A. sinensis). The support degree was set at 11 (38.46%), with a confidence coefficient of 80%, and then 38 associated pairs were screened. These results suggested that Salviae Miltiorrhizae Radix et Rhizoma, Carthami Flos is often combined with herbs for activating blood and promoting circulation of qi to treat gynecopathy, stasis blood pain syndrome, stroke and other syndromes.

RESUMO

Two new sphingolipids: oxyacanthin A [(2S,3S,4R)-2-{[(2R,5E)-2-hydroxyoctadec-5-enoyl]amino}hexaeicosane-1,3,4-triol; 1] and B [(2S,3S,4R)-2-{[(2R,5E)-2-hydroxyoctadec-5-enoyl]amino}hexaeicosane-1,3,4-triol-1-O-ß-D-glucopyranoside; 2], together with 1-octacosanol, ß-sitosterol, ß-sitosterol 3-O-ß-D-glucopyranoside and luteolin 7-O-ß-glucopyranoside were isolated from the methanolic extract of the whole plant of Carthamus oxyacantha. Their structures were elucidated using (1)H and (13)C NMR spectra and 2D NMR analyses (HMQC, HMBC and COSY) in combination with mass spectrometry (EI-MS, HR-EI-MS, FAB-MS and HR-FAB-MS) experiments and in comparison with the literature data of the related compounds. Both the compounds 1 and 2 showed inhibitory potential against lipoxygenase (LOX) in a concentration-dependent manner with IC50 values 83.3 ± 1.3 and 245.7 ± 1.1 µM, whereas compound 2 showed inhibition against enzymes acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) with IC50 values 65.3 ± 0.1 and 93.6 ± 0.1 µM, respectively.
