[Studies on tannins from Tripterygium hypoglaucum (lévl.) hutch].
OBJECTIVE
To study the tannins from Tripterygium hypoglaucum.


METHODS
Compounds were isolated by column chromatography and elucidated on the basis of spectroscopic analysis and comparison of references.


RESULTS
The compounds obtained were determined as (+)catechin, (-)epigallocatechin, procyanidin B-3, procyanidin B-4 and gallocatechin-(4 alpha-->8) epicatechin.


CONCLUSIONS
All the compounds were obtained from this plant for the first time.
