RESUMO

Sonchus (Sonchus oleraceus) originated from Europe and is now cultivated worldwide. The wild resources of sonchus are very abundant, and it has rich nutritional and medicinal value. In this study, 15 sonchus samples with typical symptoms showing leaf curling, vein thickening, and enations were collected from Guigang and Baise City of Guangxi, China. Diseased sonchus were identified by PCR detection, whole genome sequence amplification, and phylogenetic and recombination analysis. The results showed that all the samples were confirmed infected by begomoviruses, and three full-length viral genomes were obtained from 15 sonchus, named GG7-13, GG8-6, and BS63-5. The full genome lengths were 2,584, 2,735, and 2,746 nt, respectively. The nucleotide identities among the three isolates ranged from 92.67 to 99.93%. All of them shared the highest identities (greater than 91.69%) with other isolates of ageratum yellow vein China virus (AYVCNV) (available on GenBank). According to the guidelines of classification of begomoviruses, the virus isolates obtained in this study are different isolates of AYVCNV; a phylogenetic tree analysis showed that these isolates formed a large branch with three other Guangxi isolates of AYVCNV, indicating their close evolution. The genome structures of GG8-6 and BS63-5 are consistent with the monopartite genome virus of the begomoviruses, and both have six open reading frames (ORFs), while GG7-13 has a 151-nt deletion between C2 and C3, resulting in a mutant strain of only five ORFs. This study is the first report on S. oleraceus infected by ageratum yellow vein China virus.

RESUMO

This study aimed to investigate the phenolic and antioxidant properties of Egyptian Sonchus oleraceus leaves extract (SOE) while comparing the antihyperglycemic efficacy of SOE with that of conventional medicines (glibenclamide) in vivo as a substitution for insulin-deficient patients. Total phenolic (TPC) and flavonoid contents (TFC) in SOE contributed around 127.66 ± 0.56 mg GAE/gm as gallic acid equivalent (GAE) and 74.80 ± 0.55 mg QE/gm as quercetin equivalent (QE). SOE also showed significant DPPH scavenging activity at 43.46%. The presence of five phenolic and six flavonoid compounds in SOE was discovered by HPLC analysis. For the in vivo assay, 42 rats were distributed into six groups (7 Wister albino rats each). The standard control group was fed a basal diet. While the 35 rats were induced with a single dose of 100 mg kg-1 body weight (b.w.) alloxan, then treated orally with glibenclamide (GLI) at 10 mg kg-1, 100, 200, and 300 mg kg-1 SOE (positive control group) for 56 days of routine gastric oral gavages and compared to the effects of GLI, the treatment of SOE 200 and 300 mg kg-1 in diabetic rats for two months dramatically decreased blood glucose, total lipid, total cholesterol, and low-density lipoprotein cholesterol (LDLC) while boosting high-density lipoprotein cholesterol (HDLC) levels and improving liver and kidney functions. The histological assay revealed that the SOE 300 mg kg-1 treatment significantly improved the pancreas tissues, implying the potential application of Egyptian SOE as a diabetes treatment.

RESUMO

North Patrininae herba, a perennial herbaceous plant, has long been used in traditional Chinese medicine to treat appendicitis, enteritis, and dysentery. Sonchus arvensis L., Sonchus oleraceus L., and Ixeris chinensis (Thunb.) Nakai are used as substitutes for North Patrininae in different regions, but the consistency of chemical composition and efficacy of these three species is still unknown. In this study, a detailed chemical analysis was carried out of the extract obtained from Sonchus arvensis L., Ixeris chinensis (Thunb.) Nakai and Sonchus oleraceus L. and a chemical component not previously reported in Ixeris chinensis (Thunb.) Nakai was found-Luteolin-7-O-(6''-malonylglucoside). The mechanism of action of the extract against inflammation and type II diabetes was investigated using network pharmacology and analysis of blood-absorbed components following oral dosing of rats. Finally, a highly accurate and reliable method was established for quality control purposes. The results showed that Sonchus arvensis L. and Sonchus oleraceus L. may be considered potential resources of a medicinal compound, whereas Ixeris chinensis (Thunb.) Nakai requires further evaluation.

RESUMO

Traditional leafy vegetables, apart from being a staple in the diet of most of sub-Saharan Africa, are an essential part of traditional medicine and are used daily by traditional healers in the region to treat a wide variety of ailments. In this study, a batch culture technique was used to investigate whether 25 infusions from 22 traditional leafy vegetables stimulated the growth of Lactobacillus bulgaricus, Lactobacillus lactis, Lactobacillus reuteri and Bifidobacterium longum in pure culture. High performance liquid chromatography was used to determine the inulin content of the infusions. Sonchus oleraceus stimulated all four strains and Taraxacum officinale stimulated three strains. In total, 18 plants stimulated at least one of the four probiotic strains. The inulin content of the infusions varied between 2.5% and 3.6%, with Asparagus sprengeri containing the highest percentage. These results indicate that traditional leafy vegetables do stimulate the growth of the selected lactobacilli and bifidobacteria in pure culture and contain inulin. These infusions can now be tested for prebiotic potential using mixed culture systems or human hosts.

RESUMO

Sonchus oleraceus L. (Asteraceae) is a cosmopolitan species native to Europe commonly known as lettuce, sowthistle, chicory, or fake dandelion, considered a weed. However, for many years in various cultures around the world, it has been used as food and medicinal plant. The aim of this integrative review is to document the ethnomedical, phytochemical, and pharmacological information of this species. Forty-one papers document the use of S. oleraceus to heal of a wide variety of diseases. However, gastrointestinal problems, diabetes, inflammation, infections, hepatitis, wounds, and to consume it as food are the most common uses. On the other hand, only 11 items highlight that the main groups of secondary metabolites in this species are flavonoids and terpene lactones. Finally, 45 items reveal that antioxidant, antimicrobial, antiproliferative and cytotoxic were the most studied pharmacological activities. In vitro and in vivo studies of extracts and components isolated from different parts of S. oleraceus have provided a concrete overview of the pharmacological properties of this species that supports its ethnomedical uses in cultures from different parts of the world. The reports of this species have focused solely on the study of the complete plant, leaves, and aerial parts, so it is necessary to study other parts of this species to search for bioactive compounds. No clinical studies were found, which creates an opportunity to expand scientific knowledge of this species.

RESUMO

Sonchus oleraceus L. is a leafy vegetable that is usually consumed in the area of the Mediterranean and is a frequently used traditional herb to treat a variety of ailments. Previous studies deduced the potent antioxidant and cytotoxic functions of the different extracts and isolated compounds from S. oleraceus. The current study represents the first instance of chemical profiling and bioactivities of the extracted essential oil (EO) of S. oleraceus. The present investigation set out to identify the chemical components of this EO by means of Gas Chromatography with Flame Ionization Detector (GC-FID) and Gas Chromatography-Mass Spectrometry (G004-MS) techniques; assess the oil's antioxidant potencies through 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonate (ABTS) assays; and evaluate the oil's cytotoxic impact against HepG2 cancer cell lines. The GC-MS chemical profiling revealed the identification of 23 components representing 97.43% of the total oil mass within abundant cyclic ketones (20.15%), nonterpenoidial hydrocarbons (28.77%), and sesquiterpenes (42.19%). The main components were n-nonadecane (28.77%), trans-caryophyllene (23.73%), trans-methyl dihydrojasmonate (19.55%), and cis-cadina-1,4-diene (9.44%). In a dose-dependent manner, this EO demonstrated antioxidant capacities on DPPH and ABTS, with IC50 values of 609.35 and 804.16 µg/mL, respectively, compared to ascorbic acid. Using doxorubicin as a reference therapy, the MTT assay findings revealed that this oil had remarkable inhibitory effects on the proliferation of HepG2 cancer cell lines, with an IC50 of 136.02 µg/mL. More studies were recommended for further investigation of new biological roles for this oil and its main components, along with the construction of action mechanisms based on chemical components.

RESUMO

Sonchus oleraceus is a kind of medicinal and edible plant which is widely distributed. In this study, two new sesquiterpenes 1 and 2 along with three known compounds 3-5 were isolated from Sonchus oleraceus by the methods of column chromatography. The structures of the two novel compounds were constructed on the basis of HR-MS and NMR spectra. Cytotoxicities of 1 and 2 were assayed on EOMA cell lines and 1 exhibited no inhibitory effect while 2 elicited moderate inhibitory effect on EOMA cells with IC50 value of 26.5 µM. Western Blot assay indicated that 2 could suppress EOMA cell proliferation by inducing apoptosis through Bax/caspase-3 pathway.

RESUMO

Scope: Sonchus Oleraceus, named bitter vegetable (BV), has been known to have multiple health benefits such as anti-aging and anti-inflammation. However, the role of BV in the prevention of obesity is unclear. The aim of this study was to examine the effect of BV lipid extracts (BVL) on obesity development. Methods and Results: Following treatments of high fat diet-induced obese mice (C57BL/6J) with BVL (0.3 mg/g of BW per mouse) for a month, mice exhibited a significant reduction in weight gain, blood triglyceride, and fasting blood glucose compared to control mice. Intriguingly, phosphorylated AMPK, a key regulator of nutrient metabolism, was markedly increased in inguinal fat of BVL group. In 3T3-L1 cells, BVL-7 (100 µg/ml), an omega-3 fatty acid-rich fraction from BVL, lowered lipid accumulation, and down-regulated the gene expression of adipocyte markers. The inhibitory effect of BVL occurred at the early stage of adipocyte differentiation, leading to the delay of mitotic clonal expansion. AMPK knockdown by siRNA abolished the inhibitory effect of BVL-7 on adipogenesis, suggesting that AMPK is essential for BVL-regulated adipocyte differentiation. Conclusion: BVL can effectively inhibit adipogenesis through, at least in part, stimulating AMPK pathway and attenuate HFD-induced obesity. Our findings suggest that BVL can be a promising dietary supplement for protection against obesity, and the effective component of BVL can be potentially developed as anti-obesity drugs.

RESUMO

Enzymatic browning is considered a critical factor that adversely decreases the quality of fresh-cut products. Although many individual physical or chemical methods have been explored to control browning, there are few approaches combining these technologies. In the present study, Sonchus oleraceus L. extract (SOLE) and ultrasound treatment efficiently controlled the activities of polyphenol oxidase, peroxidase, phenylalanine ammonia-lyase, lipoxygenase, soluble quinones, and intermediate and advanced products, and a lower malondialdehyde content and higher antioxidant capacity were observed in fresh-cut potato slices. More than 50 phenolics and flavonoids were identified in SOLE by liquid chromatography-tandem mass spectrometry. In conclusion, the combined SOLE and ultrasound treatment could serve as a promising method for attenuating enzymatic browning.

RESUMO

Antioxidant supplementation may potentially be beneficial for embryonic development to reduce complications associated with increased levels of oxidative stress. Chlorogenic acid, one of the key polyphenolic antioxidants in S. oleraceus, was evaluated for potential protective effects during embryonic development of zebrafish exposed to the teratogen auranofin. Zebrafish embryos were transiently exposed to auranofin to induce developmental abnormalities. Phenotypic abnormalities were scored based on their severity at day 5 post-fertilization. The embryos supplemented with 250 µM chlorogenic acid showed a significantly lower score in phenotypic abnormalities compared to non-supplemented embryos after auranofin exposure. Therefore, supplementation with a low dose of chlorogenic acid showed a protective effect from auranofin-induced deformities and encouraged normal growth in zebrafish embryos. This study provides further support for the potential of using antioxidant supplementation during embryonic development for protection against malformation.

RESUMO

PREMISE: The common sowthistle, Sonchus oleraceus (Asteraceae), is a globally invasive weedy species. In order to investigate its genetic diversity, population genetic structure, and evolutionary history, we developed and characterized nuclear simple sequence repeat markers (SSRs or microsatellites). METHODS AND RESULTS: Seventeen microsatellite primer pairs were developed based on the Illumina sequence data. Ten developed SSR loci were polymorphic in four populations sampled from broad geographical regions. The number of alleles per locus ranged from one to 11, and the levels of observed and expected heterozygosity ranged from 0.000 to 1.000 and from 0.000 to 0.801, respectively. Up to 82% of the newly developed primer pairs were successfully amplified in the congeneric taxa S. asper, S. asper subsp. glaucescens, S. canariensis, and S. palmensis. CONCLUSIONS: The SSR markers developed in this study will be useful for future population genetic studies on S. oleraceus and other congeneric species.

RESUMO

BACKGROUND: Sonchus oleraceus is a large and widespread plant in the world. It is edible to humans as a leaf vegetable and is also used as a folklore medicinal herb in the treatment of infections and inflammatory disease, but limited research on its chemical constituents has been done. OBJECTIVE: To isolate and identify the bioactive ingredients from S. oleraceus. METHODS: 20kg of S. oleraceus was extracted twice with 75% alcohol. The concentrated extract was suspended in H2O and partitioned with petroleum ether, dichloromethane, ethyl acetate and n-butanol, respectively. The ethyl acetate phase was subjected to repeated normal chromatography on a silica gel column chromatography and eluted with a gradient of CH2Cl2-MeOH to give 12 crude fractions. Fraction 6 was subjected to ODS silica gel column chromatography, Sephadex LH-20 and HPLC to yield 1 and 2. Cell viability of 1 and 2 on A549, H292 and Caco2 cell lines were assayed by MTT method. Apoptosis analysis and apoptosis related proteins were detected subsequently. RESULTS: Two new sesquiterpenes were isolated from S. oleraceus and identified by NMR spectra and HR-ESIMS. 1 selectively suppressed the viability of A549 and H292 cells with IC50 values of 14.2, and 19.5µM respectively, while possessing no cytotoxicity against Caco2 cells (IC50 > 100µM). 2 did not exhibit cytotoxicity against A549, H292 and Caco2 cells (IC50 > 100µM). 1 significantly decreased the density of live cells and could cause cell apoptosis at 10 and 20µM in a dose-dependent manner. After treatment of 1 for 24h, the level of cleaved caspase-3 was increased accompanied by the reduction in procaspase-3 expression, and the downregulation of Bcl-2 was associated with the enhancement of Bax expression. 1 could lead to the up-regulation of cytochrome c and activation of caspase-9. CONCLUSION: 1 and 2 are new sesquiterpenes from S. oleraceus. 1 could induce apoptosis in A549 and H292 cells through Bax/caspase-9 pathway.

RESUMO

Edible Sonchus oleraceus Linn is a medicinal plant with many bioactivities such as anti-diabetic activity and anti-inflammatory activity. However, the main bioactive components such as polyphenols in S. oleraceus Linn are poorly absorbed in gastrointestinal tract and rapidly metabolized. Thereby, a self-emulsifying delivery system containing S. oleraceus Linn extracts (SSEDDS) was introduced to evade these problems. Herein, the anti-inflammatory effect of SSEDDS on streptozotocin-induced diabetic rats was investigated. The plasma glucose level was increased and plasma insulin level was decreased in diabetic rats. The levels of NF-κB, TNF-α, and IL-6 in the liver were significantly improved in diabetic rats (p < 0.05). Conversely, daily fed diabetic rats with 100, 200 and 400 mg/kg/day of SSEDS and 1 mg/kg/day metformin for 4 weeks, significantly (p < 0.05) restored all the above mentioned parameters to near normal levels. The immuno-histochemical studies confirmed the anti-inflammatory effects of SSEDDS.

RESUMO

The extracts of S. oleraceus Linn (SOL) and its main phenolic compounds have shown anti-diabetic effects, but their underlying mechanisms for glucose homeostasis remain unclear. The aim of this study is to evaluate the anti-diabetic mechanism of SOL by using the streptozocin (STZ) induced diabetic rat model. When diabetic rats were fed with SOL at a dose of 400 mg/kg/day for 6 weeks, the concentrations of triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) were reduced by 43%, 22%, and 16%, respectively. Meanwhile, it was also found that daily feeding of SOL to diabetic rats led to a decrease in plasma glucose level by approximately 23%. Positive effects were observed on glucose homeostasis due to the down-regulation of AMPK/Akt/GSK-3ß pathway, as indicated by the suppressions of adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK), protein kinase (Akt) phosphorylation, glycogen synthase kinase 3 beta (GSK-3ß), and the hepatic insulin resistance. In HepG2 cells, AMPK, Akt and GSK-3ß showed a consistent transcript regulation. SOL at dose of 400 mg/kg/day feeding for 6 weeks showed a positive effect comparable to metformin.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Sonchus oleraceus Linn (SOL) belongs to family of Asteraceae, is a traditional medicinal plant, which has been used to treat tumor, inflammatory diseases, infection and so on in Chinese folk culture. AIM OF THE STUDY: This work investigated the influence of aqueous ethanol extract of whole plant of SOL and contribution of its main components on inflammation METHODS AND RESULTS: Oral administration of SOL (10 mg/kg) to mice reduced the expression of inflammatory cytokines including IL-6, IL-1ß, and TNF-α, in the LPS-induced sepsis mouse model. Major phenolics in SOL were isolated and determined by HPLC. Results indicate that SOL at the concentration range from 25 to 100 µg/mL and its main components, chlorogenic acid, caffeic acid (25-100 µM) significantly reduced the pro-inflammatory cytokine IL-1ß, IL-6, TNF-α, attenuated iNOS and COX-2 expression in LPS-stimulated Macrophages. In addition, western blot analysis showed SOL suppressed inducible nitric oxide synthase (iNOS) protein expression and the phosphorylation of extracellular signal-regulated kinase (ERK), p38, c-Jun N-terminal kinase (JNK). CONCLUSION: The underlying mechanism of anti-inflammation might be in according with the inhibition of MAPKs activation as well as down regulation of iNOS and cyclooxygenase-2 (COX-2).

RESUMO

Prickly sow thistle, Sonchus asper (L.) Hill, and common sow thistle, Sonchus oleraceus L., are noxious weeds. Probably originating from the Mediterranean region, they have become widespread species. They share similar morphology and are closely related. However, they differ in their chromosome numbers and the precise relationship between them remains uncertain. Understanding their chloroplast genome structure and evolution is an important initial step toward determining their phylogenetic relationships and analyzing accelerating plant invasion processes on a global scale. We assembled four accessions of chloroplast genomes (two S. asper and two S. oleraceus) by the next generation sequencing approach and conducted comparative genomic analyses. All the chloroplast genomes were highly conserved. Their sizes ranged from 151,808 to 151,849 bp, containing 130 genes including 87 coding genes, 6 rRNA genes, and 37 tRNA genes. Phylogenetic analysis based on the whole chloroplast genome sequences showed that S. asper shares a recent common ancestor with S. oleraceus and suggested its likely involvement in a possible amphidiploid origin of S. oleraceus. In total, 79 simple sequence repeats and highly variable regions were identified as the potential chloroplast markers to determine genetic variation and colonization patterns of Sonchus species.

RESUMO

The crude extract of Sonchus oleraceus Linn (CE) and its main phenolic acids (PA), chlorogenic acid and caffeic acid have anti-diabetic activity, but the mechanisms for their effects on glucose intake remain largely unknown. Aim of this study was to examine the synergistic effect of chlorogenic and caffeic acid from S. oleraceus Linn attenuate insulin resistance and modulate glucose uptake in HepG2 cells. Major phenolic acids in SOL were isolated and identified by HPLC. Insulin-resistance HepG2 cell model was used to elucidate the effect of CE on glucose metabolism. Pre-treatment of HepG2 cells with CE or PA enhanced levels of glucose production and avoided the decrease total levels of IRS-1 triggered by high insulin concentration. CE or PA pre-treatment also could prevent the inactivation of the PI3K/AKT pathway, as well as the diminution of GLUT4 levels induced by high glucose. These findings suggested that CE and its main phenolic acids improved insulin sensitivity of HepG2 cells treated with insulin, preventing or delaying a potential hepatic dysfunction through the attenuation of the insulin signaling blockade and the modulation of glucose consumption.

RESUMO

Plants from the Asteraceae family are known to contain a wide spectrum of phytochemicals with various nutraceutical properties. One important phytochemical, chicoric acid (CA), is reported to exist in plants, such as Sonchus oleraceus and Bidens pilosa, as stereoisomers. These CA molecules occur either as the naturally abundant RR-chicoric acid (RR-CA), or the less abundant RS-chicoric acid (RS-CA), also known as meso-chicoric acid. To date, little is known about the biological activity of RS-CA, but there is evidence of its anti-human immunodeficiency virus (HIV) properties. In this study, a reliable analytical method was developed to distinguish between the two stereoisomers detected in S. oleraceus and B. pilosa. For structure identification and characterization of CA molecules, liquid chromatography-mass spectrometry (LC-MS) was used in combination with ultraviolet radiation (UV)-induced geometrical isomerization, molecular dynamics (MD) simulations, and density functional theory (DFT) models. Optimized structures from DFT calculations were used for docking studies against the HIV-1 integrase enzyme. Different retention times on the reverse phase chromatograms revealed that the plants produce two different CA stereoisomers: S. oleraceus produced the RR-CA isomer, while B. pilosa produced the RS-CA isomer. DFT results demonstrated the RR-CA molecule was more stable than RS-CA due to the stabilizing force of intra-molecular hydrogen bonding. Differences in the HIV-1 integrase enzyme binding modes were observed, with the RR-CA being a more potent inhibitor than the RS-CA molecule. The results highlight the significance of plant metabolite structural complexity from both chemical and biological perspectives. Furthermore, the study demonstrates that induced-formation of geometrical isomers, in combination with the predictive ability of DFT models and the resolving power of the LC-MS, can be exploited to distinguish structurally closely related compounds, such as stereoisomers.

RESUMO

This study was conducted to evaluate the use of the phenolic-rich Sonchus oleraceus residue as an environmentally safe approach to induce the nutritive and health-promoting values of common bean ( Phaseolus vulgaris L. cv. Bronco). S. oleraceus shoot residue, at rates of 150 and 300 g m-2, has improved soil fertility via accumulation of soil macronutrients, organic matter, organic carbon, and total phenolics. The growth and yield of bean were significantly increased. Moreover, chemical composition of the treated seeds was significantly altered, whereas higher levels of total antioxidant capacity, proteins, carbohydrates, and most of the individual phenolic acids, flavonoids, vitamins, essential amino acids, and unsaturated fatty acids were recorded. Interestingly, a concentration dependent effect was also observed, for instance, a lower saturated-to-unsaturated fatty acid ratio was only observed in the case of the lower residue rate. These findings recommend the use of S. oleraceus in organic farming of bean to enhance the health benefits of the produced seeds.
