甘西鼠尾根化学成分研究甘西鼠尾根化学成分研究

目的研究甘西鼠尾(Salvia przewalskii Maxim)的化学成分。方法应用硅胶柱色谱法对甘西鼠尾根中化学成分进行分离,根据理化常数测定和光谱(IR,FAB-MS,EI-MS,¹HNMR,¹³CNMR,¹H-¹H COSY,¹H-¹³C COSY,HMBC,NOESY)分析鉴定化合物的结构。结果获得并鉴定了8个化合物结构:丹参酮II-A(I),隐丹参酮(II),紫丹参甲素(III),柳杉酚(IV),熊果酸(V),2α,3α-二羟基乌苏-12-烯-28-酸(VI),齐墩果酸(VII),甘西鼠尾新酮A(VIII)。结论VIII为新化合物,II,IV,V,VI和VII均为首次从该植物中分得。

Chemical constituents in the roots of Salvia przewalskii Maxim.

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.
