Fund Project: The authors are grateful to A.Zeper for mass spectra measurement,and to Feng Ying Jing for NMR measurement.This study was supported by National Natural Science Foundation of China (No.30800835) and National Key Project of Scientific and Technical Supporting Programs funded by Ministry of Science&Technology of China (No.2006BAD31B05).

Two new phenylethanoid glycosides, named scroside H(1), scroside I(2), and a new secoiridoid glycoside, named picrogentioside I(3), have been isolated from the underground parts of Picrorhiza scrophulariiflora. Their structures were elucidated on the basis of spectroscopic evidence.
