Die Cardenolide der Samen von Mallotus paniculatus M ÜLL .‐A RG . (Euphorbiaceae). 2. Mitt.: Strukturbeweise. Glykoside und Aglykone, 295. Mitteilung

The structures of the following cardenolides, isolated from Mallotus paniculatus have been reported: Genin D = 11‐oxo‐uzarigenin ( 1 ), genin F = mallogenin = 11β‐hydroxy‐uzarigenin ( 3 ). Glycoside K = mallosid ( 5 ) is an L ‐rhamnoside of mallogenin, and glycoside L ( 21 ) is an L ‐rhamnoside of a new genine which we have called panogenin. Panogenin was isolated in crystalline form by the hydrolysis of panoside, and its structure was found to be that of 11β‐hydroxy‐coroglaucigenin ( 23 ). Glycoside N = glucopanoside ( 22 ), the predominant glycoside of the unfermented seeds, was found to contain one molecule of D ‐glucose bound in glycosidic form; its position was not investigated.
