Die Konstitution des Reserpins. 8. Mitteilung über Rauwolfia‐Alkaloide

Abstract

Abstract Reserpine, C 33 H 40 O 9 N 2 , has been isolated from Rauwolfia serpentina Benth . Reserpine is an ester alkaloid yielding reserpic acid, 3,4,5‐trimethoxybenzoic acid and methanol on hydrolysis. Degradation products of reserpic acid make it likely that reserpic acid is a yohimbane derivate, and a hypothetical structure for reserpine has been put forward which is in agreement with the facts known so far.
