of leaves of Macaranga tanarius resulted in the isolation of seven new prenylated flavanones, macaflavanones A-G (1-7), along with two known compounds, nymphaeol C (9) and the diterpene kolavenol. The structures of the new compounds were elucidated by means of a combination of spectroscopic methods and chemical conversion. The absolute structure of tanariflavanone B (8), isolated from the title plant
对Macaranga tanarius叶片的植物化学研究导致分离出七种新的异戊烯黄酮,macaflavanones AG(1-7),以及两种已知的化合物,如nymphaeol C(9)和二萜烯醇。通过光谱方法和化学转化的结合阐明了新化合物的结构。还分离了从标题植物中分离出来的tanariflavanone B(8)的绝对结构。使用两种细胞系分析了分离出的黄烷酮的细胞毒活性,其中马卡黄烷酮G(7)在每种情况下都是活性最高的化合物。
