The hepatoprotective activity of the ethanol extract of Astragalus kahiricus (Fabaceae) roots against ethanol-induced liver apoptosis was evaluated and it showed very promising hepatoprotective actions through different mechanisms. The extract counteracted the ethanol-induced liver enzymes leakage and glutathione depletion. In addition, it demonstrated anti-apoptotic effects against caspase-3 a...

To study the chemical constituents of Euphorbia antiquorum L., the constituents were isolated with normal-phase and reverse-phase silica gel column chromatography and their structures were elucidated on the basis of spectroscopic data. Seven terpenoids were obtained from EtOAc extract of E. antiquoru L. They were identified as antiquorine A (1), antiquorine B (2), ent-13S-hydroxy-16-atisene-3,1...

A study on the leaves of Aglaia exima led to the isolation of one new and seven known compounds: six triterpenoids and two steroids. Their structures were elucidated and analyzed mainly by using spectroscopic methods; 1D and 2D NMR, mass spectrometry, UV spectrometry and X-ray. All the triterpenoids and steroids were measured in vitro for their cytotoxic activities against eight cancer cell lin...

Two new cycloartane-type triterpene glycosides, namely cimicifoetisides A (1) and B (2), along with seven known compounds cimigenol, 25-O-acetylcimigenol, cimigenol 3-O-beta-D-xylopyranoside, 12beta-hydroxycimigenol 3-O-beta-D-xylopyranoside, cimigenol 3-O-alpha-L-arabinopyranoside, 25-deoxyshengmanol 3-O-beta-D-xylopyranoside and cimilactone A, were isolated from the rhizomes of Cimicifuga foe...

Leea indica is a medicinal plant used traditionally to cure cancer. In this study, the cytotoxic compounds of L. indica were isolated using bioassay-guided approach. Two cycloartane triterpenoid glycosides, mollic acid arabinoside (MAA) and mollic acid xyloside (MAX), were firstly isolated from L. indica. They inhibited the growth of Ca Ski cervical cancer cells with IC(50) of 19.21 μM (MAA) an...

Five new 9,19-cycloartane triterpene diglycosides, which have been named cimiaceroside C (1), and cimifosides A-D (2-5) together with the known compounds cimiracemoside D (6), cimidahurine (7) and alpha-D-glucopyranosyl-l-beta-D-fructofuranoside (8) were isolated from the rhizome of Cimicifuga foetida. The new triterpene diglycosides 1-5 were identified as cimiacerol-3-O-beta-D-xylopyranosyl-(1...

Argentatins A–C (1–3), the major cycloartane-type triterpenoids of guayule resin, a byproduct commercial rubber production, were converted into their pyrimidine (7–12), thiazole (13–15), and indole (16–18) analogues by molecular hybridization approach. The cytotoxic activities these fused heterocyclic 7–18 compared with those argentatins (1–3) against panel three sentinel human cancer cell line...

The aim of this study is a comparative metabolomic analysis between the endangered species Astragalus membranaceus and endemic thracicus concerning cycloartane saponins. In addition, in vitro shoots, callus, suspension cultures A. were successfully established to conserve biodiversity those increase amount produced comparison was made according quantity saponins astragaloside I (1), II (2), IV ...
