Abstract:
AimTo investigate the chemical composition of the root of
Salvia przewalskii Maxim. MethodsCompounds 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. ResultsEight compounds were isolated and identified as: tanshinone II-A (I), crypotanshinone (II), przewaquinone A (III), sugiol (IV), ursolic acid (V), 2α,3α-dihydroxy urs-12-ene-28-acid (VI), oleanolic acid (VII), and neo-przewaquinone A (VIII). ConclusionCompound VIII is a new compound, and compound II, IV, V, VI and VII are isolated from this plant for the first time.
