Three new flavone C-glycosides, paraquinins A-C, were isolated from the aerial parts of Paraquilegia microphylla (Royle) Dromm. et Hutch, a Tibetan medicine distributed in the Qinghai-Tibet plateau. On the basis of 1D and 2D NMR evidence, their structures were elucidated as acacetin-6-C-β-D-glucopyranosyl-(1 → 2)-β-D-glucopyranoside (1), acacetin-6-C-α-L-rhamnopyranosyl-(1 → 2)-β-D-glucopyranosyl-(1 → 2)-β-D-glucopyranoside (2), and acacetin-6-C-α-L-rhamnopyranosyl-(1 → 2)-(6'''-O-E-feruloyl)-β-D-glucopyranosyl-(1 → 2)-β-D-glucopyranoside (3).
从分布于青藏高原的藏药小花假耧斗菜（Paraquilegia microphylla (Royle) Dromm. et Hutch）的地上部分分离得到了三种新的黄酮碳苷，即对叶百部宁A - C。基于一维和二维核磁共振证据，确定它们的结构分别为刺槐素 - 6 - C - β - D - 吡喃葡萄糖基 - (1→2) - β - D - 吡喃葡萄糖苷（1）、刺槐素 - 6 - C - α - L - 鼠李吡喃糖基 - (1→2) - β - D - 吡喃葡萄糖基 - (1→2) - β - D - 吡喃葡萄糖苷（2）和刺槐素 - 6 - C - α - L - 鼠李吡喃糖基 - (1→2) - (6''' - O - E - 阿魏酰基) - β - D - 吡喃葡萄糖基 - (1→2) - β - D - 吡喃葡萄糖苷（3）。
