Abstract:
OBJECTIVETo study the chemical constituents of the bark of Paeonia suffruticosa.
METHODThe 95% ethanol extract was re-extracted with EtOAc, and then separated and purified by column chromatography using silica gel, Sephadex LH -20 and RP-18 as packing materials. The structures were identified on the basis of spectral analysis and physico-chemical characters.
RESULTSix compounds were isolated and identified as (+)-catechin (1), paeonidanin (2), paeoniflorigenone (3), 2, 5-dihydroxy-4-methoxyacetophenone (4), paeonol (5), gallic acid (6).
CONCLUSIONThe compound 1 was isolsted from the genus Paeonia for the first time. The compounds 2, 3 were isolated from this plant for the first time.
