Abstract

Potentilin A (1), a rare diflavonol ester of mu-truxinic acid and a new normonoterpenoid, 2,6-dimethyl-2,3-dihydro-4-oxo-4H-pyran-2-acetic acid (2), was isolated from Potentilla anserina, together with 19 known flavonol glycosides (3-21) and 2 known monterpenoids (22,23). Their structures were elucidated by means of UV, IR, HR-ESI-MS, 1D and 2D NMR spectroscopic data.

摘要

委陵菜素A（1）是一种罕见的μ-特鲁克斯酸二黄酮醇酯和一种新的降单萜类化合物，即2,6-二甲基-2,3-二氢-4-氧代-4H-吡喃-2-乙酸（2），它是从鹅绒委陵菜中分离得到的，同时还分离出了19种已知的黄酮醇苷（3-21）和2种已知的单萜类化合物（22,23）。通过紫外光谱、红外光谱、高分辨电喷雾电离质谱、一维和二维核磁共振光谱数据对它们的结构进行了阐明。
