[Phenylethanoid glycosides from root of Picrorhiza scrophulariiflora].
OBJECTIVE
To study the phenylethanoid glycosides from root of Picrorhiza scrophulariiflora.


METHODS
Column chromatographic techniques were used for isolation and purification of chemical constituents of the plant and the structures were identified by spectroscopic analysis.


RESULTS
Six phenylethanoid glycosides were isolated and elucidated as: 2-(3,4-dihydroxyphenyl)-ethyl-O-beta-D-glucopyranoside (1), 2-(3-hydroxy-4-methoxyphenyl)-ethyl-O-beta-D-glucopyranosyl (1-->3) beta-D-glucopyranoside (2), scroside B (3), hemiphroside A (4), plantainoside D (5) and scroside A (6), respectively.


CONCLUSIONS
Compounds 1, 2, 4 and 5 were isolated from this plant for the first time and compound 2 was firstly obtained from natural source.
