Abstract:
OBJECTIVETo study the chemical constituents of the whole plants of Pedicularis densispica.
METHODThe chemical constituents were isolated by various chromatographic methods and their structures were determined by chemical evidences and spectral data.
RESULTTen compounds were isolated and identified as acacetin (1), apigenin-7-0-beta-glucopyranoside (2), kaempferol-3,7-O-alpha-dirhamnopyranoside (3), scutellarein-7-0-beta-glucopyranoside (4), chrysoeriol-7-O-beta-glucopyranoside (5), pedicutricone A (6), dearabinosyl pneumonanthoside (7), salidroside (8), darendoside B (9), and maltol-beta-D-glucopyranoside (10).
