Two new isoprenylated flavans, kazinols E and H, and five new isoprenylated 1, 3-diphenyl-propane derivatives, kazinols C, D, F, G, and K, were isolated from the extract of the root bark of Broussonetia kazinoki SIEB. (Japanese name, Kimekozo, Moraceae). On the basis of chemical and spectral evidence, the structures of kazinols E and H were shown to be 3 and 6, respectively, and the structures of kazinols C, D, F, G, and K to be 1, 2, 4, 5, and 7, respectively.
从 Broussonetia kazinoki SIEB.(日本名 Kimekozo,桑科植物)根皮的提取物中分离出了两种新的异戊烯基黄酮类化合物 kazinols E 和 H,以及五种新的异戊烯基 1,3-二苯基丙烷衍生物 kazinols C、D、F、G 和 K。(日文名 Kimekozo,桑科)根皮的提取物中分离出来。根据化学和光谱证据,卡嗪醇 E 和 H 的结构分别为 3 和 6,卡嗪醇 C、D、F、G 和 K 的结构分别为 1、2、4、5 和 7。
