Rotenoids from the Root of Derris elliptica(Roxb.) Benth. II

AimTo study the chemical constituents of Derris elliptica (Roxb.) Benth.MethodsThe chemical constituents were isolated by various chromatographic methods, and the chemical structures were elucidated on the basis of spectral analysis.ResultsSeven rotenoids were obtained and their structures were identified as 7′-hydroxy-6a, 12a-dehydrodeguelin (1), 6-hydroxy-6a, 12a-dehydrodeguelin (2), (6aR, 12aR, 4′R, 5′S)-4′, 5′-dihydro-4′, 5′-dihydroxytephrosin (3), 6′-hydroxy-6a, 12a- dehydrorotenone (4), (-)-rotoic acid (5), (-)-deguoic acid (6), 12-deoxo-12α-acetoxyelliptone (7).ConclusionsCompound 1 is a new compound, compounds 2-6 were isolated from this genus for the first time, and compound 7 was isolated from Derris elliptica (Roxb.) Benth. for the first time.
