Chalcones And Flavans From The Bark Of Brosimum Acutifolium Subsp. Interjectum (Moraceae)

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.
