Studies on Cerbera. IV. Polar Cardenolide Glycosides from the Leaves of Cerbera odollam and Cerbera manghas

Abstract

Glucos-3-ulosyl-thevetosides of 17α-digitoxigenin and 17a-tanghinigenin were obtained from air-dried leaves of Cerbera manghas and C. odollam. From fresh leaves, oleagenin glucosyl-thevetoside and digitoxigenin gentiotriosyl-thevetoside were isolated besides known glycosides, glucosyl-thevetosides of digitoxigenin and tanghinigenin The difference between the cardenolide glycosides of the air-dried leaves and of the fresh leaves, and the glycosides patterns in the two species are discussed. © 1987, The Pharmaceutical Society of Japan.
