The target compounds were characterized by 1H NMR, IR, MS, and elemental analysis. The influences of solvent and raw material on the yield were investigated and optimum processing conditions were determined. The results of preliminary biological tests show that all those compounds exhibit certain antifungal activities.展开更多
