Three new flavanone derivatives named sorocein C (2), sorocein D (1) and sorocein H (3) together with the known artonin D, kuwanon C, cyclomorusin, and kuwanon J were isolated from the methanolic extract of the roots of Sorocea bonplandii. The structures were assigned on the basis of spectroscopic evidences.
