[Chemical constituents against hepatic fibrosis from Phyllodium pulchellum roots].

OBJECTIVE

To investigate the bioactive constituents against hepatic fibrosis from the roots of Phyllodium pulchellum.

METHODS

The chemical constituents of Phyllodium pulchellum roots were obtained by various chromatographic technologies and identified by several spectroscopic methods.

RESULTS

Ten compounds were elucidated as 3,5,2',4'-tetrahydroxy-2",2"-dimethylpyrano-[5",6",7,8] -flavanone (1), yukovanol (2), citflavanone (3), 8-prenylated 5,7,3',4'-tetrahydroxyflavanone (4), pulchelstyrene A (5), pulchelstyrene B (6), pulchelstyrene D (7), 3-indolcarbaldehyde (8), 3-methoxyindole (9) and p-hydroxybenzoic acid (10). The effects to inhibit the proliferation of activated HSC-T6 cells of all isolated compounds were also evaluated.

CONCLUSION

All compounds are isolated from this plant for the first time except for compounds 5 - 7. Compounds 2,4,5 and 6 can inhibit the proliferation of activated HSC-T6 cells in vitro.
