Objective:
To study the chemical constituents of Phlomis younghusbandii.
Methods:
Column chromatography was used in the isolation procedure. The structures of isolated compounds were elucidated by spectral data
Results:
Eight compounds were isolated and their structures were identified as barlerin (1), sesamoside (2), phloyoside II (3), salidroside (4), shanzhiside methyl ester (5), acteoside (6), luteolin-7-O-glucoside (7), daucosterol (8).
Conclusion:
Compound 4 is firstly isolated from Phlomis genus. Compound 4 and 6 are obtained from this plant for the first time.
