To investigate the chemical constituents from the rhizomes of Smilax glabra.
The compounds were isolated by column chromatography with silica gel, Diaion HP-20 and ODS as packing materials, and HPLC. Their structures were determined on the basis of their spectral evidence.
5 dihydro-flavonol glycosides were identified as: astilbin (1), neoastilbin (2), isoastilbin (3), neoisoastilbin (4), (2R, 3R)-taxifolin-3'-O-beta-D-pyranglucoside (5).
Compounds 2, 4, 5 were isolated from this plant for the first time.
研究光叶菝葜根茎的化学成分。
采用硅胶柱色谱、Diaion HP - 20和ODS作为填充材料进行柱色谱分离以及高效液相色谱法分离化合物。根据光谱数据确定其结构。
鉴定出5种二氢黄酮醇苷，分别为：落新妇苷（1）、新落新妇苷（2）、异落新妇苷（3）、新异落新妇苷（4）、(2R, 3R)-taxifolin-3'-O-β-D-吡喃葡萄糖苷（5）。
化合物2、4、5为首次从该植物中分离得到。
