摘要：
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 alpha-yl acetate and lupeol acetate and two new ursane type triterpenes characterized as urs-18 beta-H-12, 20(30)-dien-3 beta-yl acetate and 17 beta-hydroxy-28-normethyl urs-18 alpha-H-12, 20 (30)-dien-3 beta-yl acetate on the basis of spectral data analyses and chemical reactions.
