Notes:
The roots of Kanahia laniflora (FORSSK.) R. BR. contain, in addition to small quantities of cardenolides, a large amount of ester glycosides which are difficulty separable from one another. However, two of these ester glycosides were obtained in a nearly pure form. The crude mixture of ester glycosides, after mild acidic hydrolysis, gave a mixture of acyl-genins and three sugars: D-oleandrose, D-digitoxose and D-canarose, all of which were obtained in crystalline form. Acetic acid, benzoic acid and another unidentified acid were obtained on alkaline hydrolysis of the mixture of acyl-genins along with 17-isolineolon, lineolon, deacetylmetaplexigenin and a small amount of sarcostin-ketone. Besides these known genins, three probably new genins (α, τ, λ) were obtained in small, but crystalline amounts.
