Rotenoid derivatives and other constituents of the twigs of Millettia duchesnei De Wild
Three new prenylated rotenoids, elliptol (1), 12-deoxo-12α-methoxyelliptone (2) and 6-methoxy-6a,12a-dehydrodeguelin (3) were isolated from the twigs of Millettia duchesnei De Wild. together with the known compounds, 6a,12a-dehydrodeguelin, 6-hydroxy-6a,12a-dehydrodeguelin, 6-oxo-6a,12a-dehydrodeguelin, elliptone, 12a-hydroxyelliptone and eriodictyol. The structures of the novel compounds were elucidated on the basis of spectral data and chemical correlation. In addition, the full NMR data of 6-oxo-6a,12a-dehydrodeguelin and 6-hydroxy-6a,12a-dehydrodeguelin are reported here for the first time.
