Abstract

Four quaternary protoberberine alkaloids viz. palmatine (I), dehydrocorydalmine (II), palmatrubine (IV), stepharanine (V) and three tetrahydroprotoberberine alkaloids viz. tetrahydropalmatine (VI), corydalmine (VII) and stepholidine (VIII) have been isolated from the tubers of Stephania glabra. They have been characterised from their spectral (UV, IR, 1H and 13C NMR and Mass) and chemical studies. 1H-NMR of protoberberine salts (I-V) in D2O solutions are reported.
