ABSTRACT
AIM To study the chemical constituents from the fruits of Evodia rutaecarpa (Juss.) Benth.and their biological activities.METHODS The ethyl acetate fraction of 80％ ethanol extract from E.rutaecarpa was isolated and purified by silica column and recrystallization,then the structures of obtained compounds were identified by physicochemical properties and spectral data.The antitumor and antifungal activities were determined by MTT and mycelium growth method,respectively.RESULTS Ten compounds were isolated and identified as rutaecarpine (1),evodiamine (2),1-methyl-2-undecyl-4 (1H)-quinolone (3),1-methyl-2-tridecyl-4 (1H)-quinolone (4),wuchuyuamide Ⅰ (5),wuchuyuamide Ⅲ (6),wuchuyuamide Ⅳ (7),β-sitosterol (8),β-daucosterol (9),dehydroevodiamine (10).Compounds 1,2,10 had certain inhibitory effects on MDA-MB-231,LoVo,A2780 and HeLa with the IC50values of 0.65-29.45 μmol/L.Compound 1 had a certain inhibitory effect on Botrytis cinerea,Glomerella cingulata and Rhizoctonia solani with the inhibitory rates of 18.12％-49.57％.CONCLUSION Compounds 3-7 are isolated from this plant for the first time,compounds 1,2,10 have strong biological activities.
ABSTRACT
Rhetsinine has been isolated from the fruits of Evodia rutaecarpa ( Juss. ) Benth. ~1H NMR and ~(13)C NMR assignments reported previously for rhetsinine were revised on the basis of UV, IR, ESI-MS,~1H NMR, ~(13)C NMR and X-ray crystallographic analysis.
ABSTRACT
Object To investigate the berberine in Coptis chinensis Franch. processed with various quantity of Evodia rutaecarpa (Juss.) Benth. and the components absorbed from E. rutaecarpa. Methods Taking berberine, evodiamine and rutaecarpine as targets, HPLC method was used to determine the components of C. chinensis, E. rutaecarpa, C. chinensis processed with 10%, 20%, 30%, 40%, 50% E. rutaecarpa. Results The content of berberine in C. chinensis processed with E. rutaecarpa decreased, and that of C. chinensis processed with 20% and 30% E. rutaecarpa was higher than the rest. C. chinensis processed with E. rutaecarpa absorbed the components of E. rutaecarpa really. Conclusion The suitable quantity of E. rutaecarpa is 20% when processing for C. chinensis.
