Phytochemistry,1999,51(8):1031–1037. | Dammarane triterpenes and pregnane steroids from Aglaia lawii and A. tomentosa[Reference: WebLink] |
METHODS AND RESULTS:
Three known dammaranes, cabraleone, eichlerianic acid and shoreic acid, together with two new ones, aglinins A and B, were isolated from the bark of Aglaia lawii. A. tomentosa also contained dammarane triterpenes: the known, cabraleone, Cabraleadiol 3-acetate, 3-epiocotillol, cabralealactone, cabralealactone 3-acetate and the new aglinins C and D. | Phytochemistry,1985,24(12): 2925–2928. | Dammarane Triterpenes from the stem bark of Commiphora Dalzielii.[Reference: WebLink] |
METHODS AND RESULTS:
From the stem bark of Commiphora dalzielii the isolation and identification of the 20,24-epoxydammarane triterpenes Cabraleadiol 3-acetate, cabraleadiol and cabraleone and isofouquierone are reported. Both the acetate and isofouquierone appear to be novel. The chemotaxonomic implications of finding this type of triterpene in the Burseraceae are discussed. |
