New Phenyl Propanoids from Cryptocarya bracteolata

Abstract

Two new phenyl propanoids were extracted from the bark of Cryptocarya bracteolate Gamb., ethyl 3-(2′-hydroxy-3′,4′,5′-trimethoxyphenyl) propanoate (1) and ethyl 3-(2′-glucosyl-3′,4′,5′-trimethoxyphenyl)propanoate(2), together with seven known alkaloids, (+)-lirioferine (3), (+)-bracteoline (4), (+)-reticuline (5), (+)-reticulineN-oxide (6), (-)-norargemonine (7), (+)-bisnorargemonine (8) and atherolin (9). The structures of compounds were established through several spectroscopic methods; ID and 2D-NMR, UV, IR and MS.
