Notes:
The wood of Anodendron paniculatum contains a large number of cardenolides; 14 of such compounds could be spottet in PC. and TLC. with Kedde reagent. Five of these (A, E 1, E 2, F, and G) could be isolated in crystalline form and two other ones (B 1 and B 2) as an amorphous mixture. A crystalline aromatic ketone (compound α) was obtained as by-product. The isolated cardenolides, named as anodendrosides A-G, were found to be glycosides containing unusual sugars. According to UV. and IR. spectra the genin portion in anodendroside E 1 (probably also in F and B 2) contains a cardenolide structure with saturated ring D and normal butenolide side-chain, while the anodendrosides A, E 2 and G (probably also B 1) contain an additional double bond at C-16. The four compounds for which IR. spectra could be taken (A, E 1, E 2, and G) possess a keto group.
