The aim of the study was to analyze the constituents of the dichloromethane fraction obtained from A. moluccana and also to evaluate the anti-inflammatory and antinociceptive properties of α,β-amyrenone isolated from A. moluccana in mice. The dichloromethane fraction was evaluated by gas chromatography and submitted to purification. The mixture of α,β-amyrenone was isolated and then evaluated u...
A multifunctional oxidosqualene cyclase from Tripterygium regelii that produces both α- and β-amyrin
Dandelion extracts have been studied extensively in recent years for its anti-depressant and anti-inflammatory activity. Recent work from our lab, with in-vitro systems, shows the anti-cancer potential of an aqueous dandelion root extract (DRE) in several cancer cell models, with no toxicity to non-cancer cells. In this study, we examined the cancer cell-killing effectiveness of an aqueous DRE ...
BACKGROUND Lycnophora pinaster is used by the traditional Brazilian medicine for the treatment of inflammations. Anti-inflammatory activity of Lycnophora pinaster was investigated for extracts, fractions, and isolated compounds of their aerial parts. The hexane extract (HE) provided α-amyrin, lupeol, mixture of α-amyrin and lupeol, mixture of 3-O-acetyl-lupeol and 3-O-acetyl-pseudotaraxasterol,...
Morbidity and mortality of the infected patients by multidrug-resistant bacteria have increased, emphasizing urgency fight for discovery new innovative antibiotics. In this sense, natural products emerge as valuable sources bioactive compounds. Among biodiversity, Eryngium pristis Cham. & Schltdl. (Apiaceae Lindl.) is traditionally used to treat thrush ulcers throat mouth, diuretic emmenago...
Hoya lacunosa, Asclepiadaceae, C-Glycosylflavonoids, Latex, Triterpenoids, 4-ar-Methylsterols Hoya lacunosa leaves contain some main C-glycosylflavonoids, which were identified as: 6-Carabinosyl 8-C-glucosylapigenin (isoschaftoside), 6-C-glucosyl 8-C-arabinosylapigenin (schaftoside) and 6,8-di-C-arabinosylapigenin. In the latex triterpenols were found, often both free and in ester form, of whic...
In addition to benjaminamide (2), β-amyrin, β-amyrin acetate, lupeol, betulinic acid, β-sitosterol glucoside, a new ceramide glycoside was isolated from the woods of Ficus lutea Vahl (Moraceae). Using mass fragmentation pattern, 1 and 2D NMR spectra and by comparison with published data, the new compound was characterized as 1-O-β-D-glucopyranosyl-(2S,3R,5E,12E)-2N-[(2'R)-hydroxyhexadecanoyl]-o...
AIM OF THE STUDY Investigate the hypoglycaemic activity of the four isolated compounds from a crude acetone extract of the root bark of Euclea undulata var. myrtina, which is used by traditional healers in the Venda area, Limpopo Province in the treatment of diabetes. MATERIAL AND METHODS The hypoglycaemic activity of the four compounds isolated from Euclea undulata was determined by in vitro...
