Abstract

Aim: To investigate the chemical composition of the root of Salvia przewalskii Maxim.

Methods: Compounds were isolated by silica gel column chromatography. Structures of these compounds were elucidated by spectral analysis (EI-MS, FAB-MS, 1HNMR, 13CNMR, 1H-1H COSY, 1H-13C COSY, HMBC, NOESY) and phytochemical properties.

Results: Eight compounds were isolated and identified as: tanshinone II-A (I), crypotanshinone (II), przewaquinone A (III), sugiol (IV), ursolic acid (V), 2 alpha, 3 alpha-dihydroxy urs-12-ene-28-acid (VI), oleanolic acid (VII), and neo-przewaquinone A (VIII).

Conclusion: Compound VIII is a new compound, and compound II, IV, V, VI and VII are isolated from this plant for the first time.
