|Title:||New pentacyclic triterpenic esters from the roots of Calotropis gigantea|
|Abstract:||Phytochemical studies on the roots of Calotropis gigantea resulted in the isolation of one new lupene type triterpene identified as lup-13 (18), 19 (29)-dien-9-yl acetate and lupeol acetate and two new ursane type triterpenes characterized as urs- 18β-H-12 , 20(30)-dien-3β -yl acetate and 17β -hydroxy-28-nornethyl urs-18-H-12, 20 (30)-dien-3β -yl acetate on the basis of spectral data analyses and chemical reactions.|
