To study the chemical constituents of the fruits of Polygonum orientale L., silica gel and ODS column chromatography methods were used to separate and purify the constituents. Their structures were elucidated on the basis of physicochemical properties and spectral analysis. Three compounds were identified as 28-O-beta-D-glucopyranosyl-3beta, 7beta-dihydroxy-lup-20 (29)-en-28-oate (1), 5,7-dihydroxychromone (2) and naringenin (3). Compound 1 is a new triterpenoid saponin and others were isolated from the fruits of this plant for the first time.
为研究红蓼果实的化学成分，采用硅胶柱色谱和ODS柱色谱法对其成分进行分离纯化。根据理化性质和光谱分析确定其结构。鉴定出3种化合物，分别为28 - O - β - D - 吡喃葡萄糖基 - 3β，7β - 二羟基 - 羽扇 - 20（29）- 烯 - 28 - 酸酯（1）、5,7 - 二羟基色酮（2）和柚皮素（3）。化合物1是一种新的三萜皂苷，其他化合物均为首次从该植物果实中分离得到。
