Abstract

Three new prenylchalcones, antiarones C, D, and E along with four new prenylflavonones, antiarones F, G, H, and I were isolated from the root bark of Antiaris toxicaria Lesch. On the basis of spectral evidence, the structures of antiarones C - I were shown to be 2 - 8, respectively. A known compound, (±)-sigmoidin A (1) was also isolated.
