Abstract:
OBJECTIVETo study the phenylethanoid glycosides from root of Picrorhiza scrophulariiflora.
METHODColumn chromatographic techniques were used for isolation and purification of chemical constituents of the plant and the structures were identified by spectroscopic analysis.
RESULTSix 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.
CONCLUSIONCompounds 1, 2, 4 and 5 were isolated from this plant for the first time and compound 2 was firstly obtained from natural source.
