[Study on oil-soluble components obtained from the fruit of Evoldia rutaecarpa].

OBJECTIVE: To extract and isolate the biologic-active components of the oil-soluble components obtained from the fruit of Evodia rutaecarpa. METHODS: Various chromatographic techniques were used to isolate and purifie the biologic-active components, the IR and NMR spectra were used to identify the structure of this compound from Evodia rutaecarpa, and the content and the chemical structure was calibrated with a standard mixture was by TLC. RESULTS: A crystal compound was isolated from the Evodia rutaecarpa of Rutaceae, and was elucidated as oleanolic acid. CONCLUSION: The main chemical constituents of oil-soluble components obtained from the fruit of Evodia rutaecarpa are terpenoid compounds, the content of oleanolic acid is 1.8%.
