From the underground parts of Picrorhiza scrophulariiflora, three new caffeoyl glycosides, scrocaffeside A-C (1-3), together with two caffeic acid derivates, 4-O-beta-D-glucopyranosyl caffeic acid (4) and 4-methoxy caffeic acid (5) and a phenylethanoid glycoside, scroside D (6), were isolated. Their structures were elucidated on the basis of chemical and spectroscopic evidence and comparisons with literature data of related compounds.
从胡黄连的地下部分分离得到了三种新的咖啡酰糖苷，即胡黄连咖啡苷A - C（1 - 3），以及两种咖啡酸衍生物，4 - O-β-D-吡喃葡萄糖基咖啡酸（4）和4 - 甲氧基咖啡酸（5），还有一种苯乙醇苷，胡黄连苷D（6）。通过化学和光谱证据以及与相关化合物文献数据的比较，阐明了它们的结构。
