Eight indole alkaloids, melosines A-H, together with 13 known alkaloids, were isolated from the fruits of Melodinus cochinchinensis. The structure elucidation of isolated secondary metabolites was based on comprehensive spectroscopic data analysis. Melosine B showed moderate cytotoxic activity against five human cancer cell lines, HL-60, SMMC-7721, A-549, MCF-7, and SW480 with IC50 values ranging from 1.6 to 8.1μM.
从越南酒饼叶的果实中分离出8种吲哚生物碱，即美乐新碱A - H，以及13种已知生物碱。通过综合光谱数据分析对分离得到的次生代谢产物进行结构解析。美乐新碱B对HL - 60、SMMC - 7721、A - 549、MCF - 7和SW480这5种人类癌细胞系显示出中等细胞毒性活性，IC50值在1.6至8.1μM之间。
