Planta Med. 1992 Apr;58(2):192-6. doi: 10.1055/s-2006-961427.

Abstract

From the herb of AERVA LANATA six alkaloids were isolated. Canthin-6-one ( 1) and beta-carboline-1-propionic acid ( 5) have been found previosly while 10-methoxy-canthin-6-one ( 2), 10-hydroxy-canthin-6-one ( 3),10- O-beta- D-glucopyranosyloxycanthin-6-one ( 4), 6-methoxy-beta-carboline-1-propionic acid ( 6) are new alkaloids. Their structures were determined by means of spectoscopic analysis and chemical transformations.
