OBJECTIVE
To study the chemical constituents of Phlomis younghusbandii.
METHODS
Compounds were isolated from the ethanolic extract by silica gel column chromatography, and their structures were identified by physical and chemical evidences and spectral methods.
RESULTS
Eight compounds were isolated and identified respectively as 8-acetylshanzhiside methyl ester (1), shanzhiside methyl ester (2), phlomiol (3), 2-butoxy-2-(hydroxymthyl) tetrahydro-2H-3,4,5-pyrantriol (4), sesamoside (5), pulchelloside-I (6), luteolin-7-O-beta-D-glucopyranoside (7) and daucosterol (8).
CONCLUSIONS
All the compounds were isolated from the plant for the first time.
