Abstract This manuscript describes the chemical investigation of the bark from Brosimum acutifolium subsp. interjectum, a subspecies with restricted distribution in the Amazon rainforest. A total of seven flavonoids were isolated, including kanzonol B–C and corylifol B, all not previously described from B. acutifolium. Also, corylifol B is described for the first time from the Moraceae family. To the best of our knowledge, this is the first report on the phytochemistry of Brosimum acutifolium subsp. interjectum.

摘要 这份手稿描述了对 Brosimum acutifolium subsp. 树皮的化学研究。interjectum，一种在亚马逊雨林中限制分布的亚种。总共分离出 7 种黄酮类化合物，包括 kanzonol B-C 和 corylifol B，之前都没有从 B. acutifolium 中描述过。此外，首次从桑科中描述了corylifo B。据我们所知，这是关于 Brosimum acutifolium subsp 植物化学的第一份报告。插话。
