摘要:
采用D101大孔吸附树脂、ODS柱色谱以及制备型高效液相色谱等方法对青天葵Nervilia fordii (Hance)Schltr. (Orchidaceae)植物地上部分的化学成分进行研究,从中得到两个新的黄酮苷类化合物nervilifordin K (1)和nervilifordin L (2)。通过1D-, 2D-NMR, HR-ESI-MS以及其他化学方法鉴定化合物1为rhamnocitrin-3-O-β-glucopyranosyl-4'-O-β-galactosyl-(1→3)-glucopyranoside,命名为nervilifordin K,化合物2为7,3'-di-O-methylquercetin-4'-O-[β-galactosyl-(1→3)-β-glucopyranosyl]-3-O-β-glucopyranoside,命名为nervilifordin L。

Abstract:
Two new flavonoid glycosides were isolated from the aerial parts of Nervilia fordii by various chromatographies such as D101 macroporous resin, ODS and preparative HPLC chromatographic techniques. Their structures were elucidated as rhamnocitrin-3-O-β-glucopyranosyl-4'-O-β-galactosyl-(1→3)-glucopyranoside (1) and 7, 3'-di-O-methylquercetin-4'-O-[β-galactosyl-(1→3)-β-glucopyranosyl]-3-O-β-glucopyranoside (2) on the basis of extensive spectroscopic analyses, including 1D-, 2D-NMR, HR-ESI-MS and analytical hydrolysis.
