摘要：
Two new racemic C-benzylated flavanones (1a, 2a) were isolated from the root bark of Uvaria chamae (Annonaceae). The structures were proposed as the 5-methyl ether derivatives of dichamanetin (1b) and chamanetin (2b) based on spectral data and conversion to known compounds. The 13C nmr data for a number of methyl ether derivatives of chamanetin (2b) and dichamanetin (1b) are discussed. © 1979, American Chemical Society. All rights reserved.
