摘要：
Two new flavones, 6,4′-dimethoxy-8-formylflavone (1) and 6,7-dimethoxy-8-acetyl-4′-hydroxyflavone (2), together with five known flavones (3–7), were isolated from the leaves and stems of Hypericum chinense. The structure of 1–7 was elucidated by spectroscopic methods including extensive 1D and 2D NMR techniques. Compounds 1, 2, 6, and 7 were evaluated for their anti-tobacco mosaic virus (anti-TMV) activity. The results showed that compound 1 shows high anti-TMV activity with an inhibition rate of 31.4%, which is close to that of the positive control.
