摘要：
Two new flavonoids, 8-formyl-3',4'-dihydroxy-6,7-dimethoxyflavone (1) and 8-formyl-4'-hydroxy-3',6,7- trimethoxyflavone (2), were isolated from the fruits of Ziziphus jujuba Mill. Their structures were elucidated on the basis of extensive NMR and MS means. The anti-tobacco mosaic virus (anti-TMV) and antioxidant activity of 1 and 2 were evaluated. They both showed anti-TMV activity with inhibition rates of 92.8% and 88.6%, and antioxidant activity with an IC50 value of 3.16 mu g/mL and 3.87 mu g/mL, respectively.
