Abstract

A new flavonol glycoside, kaempferol 3-O-α-L-rhamnopyranosyl (1 → 6)-O-[β-D-glucopyranosyl (1 → 2)-O-β-D-galactopyranosyl (1→2)]-O-β-D-glucopyranoside (1), together with a known compound, kaempferol 3-O-β-D-glucopyranosyl (1 → 2)-O-β-D-galactopyranosyl (1 → 2)-O-β-D-glucopyranoside (2) was isolated from the seeds of Nigella glandulifera. Their structures were elucidated on the basis of spectral analysis, including ESI-MS, ESI-MS/MS, HR-ESI-MS, DQF-COSY, TOCSY, HSQC and HMBC techniques.

摘要

从黑种草种子中分离得到一个新的类黄酮糖苷，山柰酚 3-O-α-L-鼠李吡喃糖苷（1→6）-O-[β-D-吡喃葡萄糖基（1→2）-O-β-D-半乳糖吡喃糖苷（1→2）]-O-β-D-吡喃葡萄糖苷（1），以及一个已知化合物，山柰酚 3-O-β-D-吡喃葡萄糖基（1→2）-O-β-D-半乳糖吡喃糖苷（1→2）-O-β-D-吡喃葡萄糖苷（2）。基于光谱分析，包括 ESI-MS、ESI-MS/MS、HR-ESI-MS、DQF-COSY、TOCSY、HSQC 和 HMBC 技术，确定了它们的结构。
