Objective: To study the chemical constituents from the crop pathogenic fungus active fraction of Wisteria sinensis tumor.
Methods: The chemical constituents were extracted of different concentrations and isolated by silica gel and Sephadex LH-20 column. The chemical structures of components were further elucidated by the physicochemical characters and MS, NMR spectral data.
Results: Ten compounds were isolated and identified as dibutyl phthalate (1), diacetonealcohol (2), pinoresinol (3), stellasterol (4), oleanolic acid (5), olean-12-ene-3-oxo-22,24-diol (6), betulinic acid (7), 2',4',4-hydroxy-chalcone (8), avicularin (9) and quercetin-3-O-β-D-glucopyranoside (10).
Conclusion: All the compounds are isolated from the genus for the first time.
