ABSTRACT
Two new phytoconstituents characterized as n-tetradecanyl n-hexadec-9-enoate (n-tetradecanyl palmitoleate) (4) and 18µH – urs– 12 – en - 3β, 25 - olide (proceraursenolide) (5) have been isolated for the first time from the roots of Calotropis procera (Ait.) R. Br. (Asclepiadaceae) along with the known compound tridecanoyl glycerol (1), 1-octadec-9′-enoyl -2,3- dihexadecanoyl glycerol (2), tridocosanoyl glycerol (3), urs-12-en-3β-olyl acetate (α-amyrin acetate) (6) and 18αH-urs-12, 20(30)-dien-3β-yl acetate (7). The structures of all these phytoconstituents have been established by spectral data analysis and chemical reactions.
