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.
通过D101大孔树脂、ODS和制备型高效液相色谱等多种色谱技术，从青天葵地上部分分离得到两种新的黄酮苷。通过广泛的光谱分析，包括一维、二维核磁共振、高分辨电喷雾电离质谱和分析水解，确定它们的结构分别为鼠李柠檬素-3-O-β-吡喃葡萄糖基-4'-O-β-半乳糖基-(1→3)-吡喃葡萄糖苷(1)和7,3'-二-O-甲基槲皮素-4'-O-[β-半乳糖基-(1→3)-β-吡喃葡萄糖基]-3-O-β-吡喃葡萄糖苷(2)。
