Notes:
Pentacyclic triterpenes, sterols, cardenolides and pregnane derivatives could be identified in extracts from roots of Glossostelma carsoni (N.E. BR.) Bullock. From the first group, the following substances could be isolated in crystalline form: β-amyrin, lupeol, their 3-O-acetyl derivatives, and 3-O-isovaleryl-β-amyrin. The sterols were isolated in the form of two mixed but crystalline fractions. The less polar fraction was shown to be a mixture of β-sitosterol, campesterol, stigmasterol, and cholesterol (stereoisomers are not excluded); the more polar fraction is probably a mixture of monohydroxy derivatives of the four above mentioned sterols.
