摘要：

Two new isoprenylated flavones, bracteflavones A and B (1 and 2), together with four known isoprenylated flavones (3-6) were isolated from the twigs of Garcinia bracteata. Their structures were elucidated by spectroscopic methods, including extensive 1D- and 2D- NMR techniques. The anti-tobacco mosaic virus (anti-TMV) activities of compounds 1-6 were evaluated, and the results revealed that 1-6 showed potential anti-TMV activity with inhibition rates in the ranges of 17.6-24.3%, respectively.
