丹参有效成分的研究——Ⅴ.紫丹参甲素和乙素的分离和化学结构

STUDIES ON THE ACTIVE PRINCIPLES OF DAN-SHEN Ⅴ. ISOLATION AND STRUCTURES OF PRZEWAQUINONE A AND PRZEWAQUINONE B

    摘要
  • 摘要: 从云南产紫丹参(Salvia przewalskii Maxim.var.mandarinorum Stib.)中分离到两种新的二萜醌类化合物,取名为紫丹参甲素(C19H18O4,熔点173～5℃)和紫丹参乙素(C14H12O(4),熔点242～3℃),经物理和化学方法的研究推定其结构式分别为(Ⅰ)和(Ⅱb)。紫丹参甲素有抗动物肿瘤活性,且其抑菌作用比隐丹参酮强。试探了紫丹参乙素质谱中M-16裂片的裂解由来。

     

    Abstract: Two new diterpenequinones named przewaquinone A and przewaquinone B were isolated from Salvia przewalskii Maxim. var. mandarinorum (Diels) Stib.The structures of przewaquinone A (C19 H18 O4, mp 173-5℃) and przewaquinone B (C18 H12 O4, mp 242-3℃)were elucidated as (Ⅰ) and (Ⅱb) by spectral analyses and chemical methods, respectively.Przewaquinone A was shown to have antitumor activities on mice and to exhibit stronger inhibition against Staphylococcus aureus than cryptotanshinone.
