[Studies on the chemical constituents of Balaophora polyandra].
OBJECTIVE
To study the chemical constituents of Balaophora polyandra.


METHODS
The chemical constituents were isolated by column chromatography on silica gel, Toyopearl HW-40C and Sephadex LH-20. Their structures were elucidated on the basis of spectral analysis.


RESULTS
8 compounds have isolated from this plant, and the structure of them have identified as Gallic acid (1), Ellagic acid (2), Ferulic acid (3), Caffeic acid (4), p-hydroxylcinnamic acid (5), 1,3-di-O-galloyl-4,6-(S) - hexahydroxydiphenyl-beta-D-glucopyrannose (6),1-O-(E) - caffeoyl- 3-O-galloyl-beta-D-glucopyrannose (7), 2-O-(E) - caffeoyl-1-O-[see symbol] - (E) - coumaroyl-beta-D-glucopyrannose (8).


CONCLUSIONS
Compounds 1 - 8 are isolated from this plant for the first time.
