Two new prenylflavanones, tanariflavanones A (1), and B (2), and one known compound, (-)-nymphaeol-C (3), were isolated from the fallen leaves of Macaranga tanarius. Compounds 1 and 2 showed inhibition of radical growth of lettuce seedlings at 200 ppm. Their structures were elucidated primarily by NMR, circular dichroism, and mass spectroscopic methods.
从红背桂的落叶中分离出两种新的异戊烯基黄酮类化合物，塔纳瑞黄酮A（1）和B（2），以及一种已知化合物（-）-睡莲素-C（3）。化合物1和2在200 ppm浓度下对生菜幼苗的胚根生长有抑制作用。它们的结构主要通过核磁共振、圆二色光谱和质谱方法确定。
