The chemical investigation of the leaves and stem bark of Acacia polyacantha (Fabaceae) led to the isolation of a new oleanane-type triterpenoid saponin named polyacanthoside A 1 together with fifteen known compounds. Their structures were established from spectral , mainly HRESIMS, 1D NMR and 2D NMR and by comparison with literature data. The cytotoxicity of compound 1 and the analogues 8 as well
对金合欢(Fabaceae)的叶子和茎皮进行化学研究后,分离出了一种名为聚棘皮苷A 1的新型齐墩果型三萜皂苷和十五种已知化合物。它们的结构由光谱,主要是HRESIMS,1D NMR和2D NMR建立,并与文献数据进行比较。在包括敏感和耐药表型的9种癌细胞系中确定了化合物1和类似物8以及阿霉素的细胞毒性。与类似物8不同,化合物1和阿霉素在所有9种测试的IC 50癌细胞系中均显示出细胞毒性作用化合物1的值范围从8.90μM(对CCRF-CEM白血病细胞)到35.21μM(对HepG2肝癌细胞),对于阿霉素,范围从0.02μM(对CCRF-CEM白血病细胞)到66.83μM(对CEM / ADR5000白血病细胞)。 。
