Abstract

Two new phenylpropanoid-substituted epicatechins, namely, catiguanin A ( 1) and catiguanin B ( 2), were isolated from the bark of Trichilia catigua along with four known compounds, cinchonain Ia ( 3), cinchonain Ib ( 4), cinchonain Ic ( 5), and cinchonain Id ( 6). The structures of 1 and 2 were elucidated by analysis of spectroscopic data and by comparison of their NMR data with those of previously reported cinchonains. The isolated compounds exhibited potent antioxidant activity in the alpha,alpha-diphenyl-beta-picrylhydrazyl (DPPH) radical scavenging test, with IC 50 values in the 2.3-9.4 microM range.
