[Study on chemical constituents from crop pathogenic fungus active fraction of Wisteria sinensis tumor].

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).

CONCLUSIONS

All the compounds are isolated from the genus for the first time.
