Abstract:

Phlomis umbrosa is a traditional medicinal plant, distributed in the north of China. In the west of Hubei province, its roots were used in the treatment of the rheumatic diseases in Tujia nationality. To study the chemical constituents from the rhizome of Phlomis umbrosa chemical constituents were isolated from the plant by using repeated silica gel, toyopearl HW-40 and preparative HPLC chromatography. The structures of the compounds were elucidated on the basis of one and two dimensional NMR spectroscopic techniques and HRESI-MS. Ten compounds, 6"-syringyl-sesamoside (1), decaffeoylverbascoside (2), calcelarioside B (3), verbascoside (4), isoverbascoside (5), alyssonoside (6), sesamoside (7), shanzhiside methyl ester (8), 8-acetyl-shanzhiside methyl ester (9), 7-epiphlomiol (10) were isolated from P. umbrosa. Compound 1 is a new compound. Compounds 2-6 are isolated from this plant for the first time.
