[Chemical constituents from roots of Phlomis umbrosa].
OBJECTIVE
To study the chemical constituents of Phlomis umbrosa.


METHODS
Chemical constituents were isolated by repeated column chromatography (Toyopearl HW-40C and preparative HPLC). The structures were elucidated on the basis of spectral data analysis.


RESULTS
Thirteen compounds were identified as oleanolic acid (1), corosolic acid (2), hederagenin (3), arjunolic acid (4), belleric acid (5), 3beta-hydroxy-29-al-12-en-28-oleanoic acid (6), butyrospermol (7), beta-sitosterol (8), daucosterol (9), caffeic acid (10), vanillic acid (11), p-hydroxy-benzoic acid (12), 3, 4-dihydroxy-benzoic acid (13).


CONCLUSIONS
Compounds 3 9, 11-13 were isolated from the plant for the first time.
