new naturally occurring phenanthrene-1,4-quinone, annoquinone-A, along with parietin (physcion) and β-sitostenone were isolated from the stem bark of Annona montana . The structure of annoquinone-A was elucidated by spectral methods and synthesis. Annoquinone-A demonstrated potent antimicrobial activity against Bacillus subtilis and Micrococcus luteus as well as cytotoxicity in the KB ( ED 50 = 0.16
摘要 从番荔枝的茎皮中分离到了一种新的天然存在的菲-1,4-醌,苯醌-A,以及parietin (physcion) 和β-sitostenone。苯醌-A的结构通过光谱方法和合成阐明。Annoquinone-A 在 KB (ED 50 = 0.16 μg/ml) 组织培养试验中显示出对枯草芽孢杆菌和藤黄微球菌的有效抗菌活性以及细胞毒性。β-Sitostenone 也显示出显着的细胞毒性。
