Novel N-containing rotenoid and seco-rotenoid from the root of Derris elliptica

Abstract

Two new rotenoids, 2-hydroxy-5-aminorotenonone (1) and elliptoic acid (2), were isolated from the roots of Derris elliptica collected in Guangdong Province, China. Their structures were established by extensive spectral analysis. Compound 1 is the first N-containing rotenoid and compound 2 is the third rotenoid with the cleavage of C(12)–C(12a).
