Plant-derived antitumor drugs are currently used in chemotherapy. Cycloartane triterpenoids have shown a cytotoxic effect on human prostate cancer cells. The aim of the present study was to isolate a cycloartane triterpenoid from Commiphora myrrha and evaluate its anticancer potential. Cycloartan-24-ene-1α,2α,3β-triol (MY-1) was isolated from Commiphora myrrha, and its structure was determined ...
Phytochemical analysis of A. balsamea oleoresin led to the isolation of three new 3,4-seco-lanostane triterpenoids 1-3, one new cycloartane triterpenoid 4 along with fourteen known terpenoids. Structure determinations were based on extensive 1D/2D NMR, IR and MS spectroscopic analyses, and comparison with literature data. The isolated compounds were evaluated in vitro for their cytotoxicity aga...
Gardenia plants have long been used as traditional medicines in various countries including Thailand. In this study, two new 3,4-seco-cycloartane triterpenes, sootependial (1) and sootepenoic acid (2), were isolated from bud exudate of G. sootepensis, together with five known compounds. Their structures were elucidated on the basis of spectroscopic data. Sootependial (1) showed potent cytotoxic...
Three new cycloartane triterpene glycosides, soulieosides A (1), B (2), and C (3), were isolated from the rhizomes of Souliea vaginata, and their structures were elucidated on the basis of extensive NMR experiments and chemical methods. Soulieosides A-C were assigned as 25-O-acetylcimigenol-3-O-beta-D-(2-acetyl)xylopyranoside (1), 24-O-acetyl-isodahurinol-3-O-beta-D-(2-acetyl)xylopyranoside (2)...
euphorbia macrostegia or persian wood spurge is one of the seventeen endemic plants of this genus in iran. three triterpenoids: 24-methylenecycloartan-3β-ol (1), butyrospermol (2) and cycloartenol (3) and three diglycerides: 1,2-di-o-α-linolenoyl-sn-glycerol (4), 1-o-linoleoyl-3-o-palmitoyl-sn-glycerol (5) and 1-o-α-linolenoyl-2-o-palmitoyl-sn-glycerol (6) were isolated from a hexane layer of m...
