摘要

From the underground parts of Picrorhiza scrophulariiflora, scrocaffeside D (1), methyl-4-O-β-Dglucopyranosyl-5-methoxy ferulic acid (2), phenethyl-β-D-glucopyranoside (3), veratric acid (4), were isolated. Scrocaffeside D (1) was a new one, and other known compounds were also isolated from the plants of Picrorhiza Royle for the first time. Their structures were elucidated on the basis of chemical and spectroscopic evidence and comparisons with the literature data of related compounds.
