sesamoside and luteolin-7-glucoside

To study the chemical constituents of Phlomis younghusbandii.. Column chromatography was used in the isolation procedure. The structures of isolated compounds were elucidated by spectral data. 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).. Compound 4 is firstly isolated from Phlomis genus. Compound 4 and 6 are obtained from this plant for the first time.
