Limonoids and quinoline alkaloids from Dictamnus dasycarpus.
Phytochemical investigation on Dictamnus dasycarpus (Rutaceae) has led to the isolation of four new secondary metabolites (2, 6, 9, and 10) along with twelve known phytochemicals (1, 3- 5, 7, 8, 11-16). Compound 4 was isolated as a natural product for the first time. The structures of compounds 1-16 were elucidated by extensive spectroscopic analyses and comparison with previously reported spectroscopic data. The structures of 8 and 13 were further confirmed based on X-ray data analyses. The absolute configuration of compounds 8-12 were studied based on the CD spectra analyses.
