[Study on the chemical constituents of Phlomis younghusbandii].

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.
