Özet: For more bioactive compounds, p hytochemical investigations of the acetone extract of the twigs G arcinia multiflora resulted in the isolation of two new bipheny ls, multiflorabiphenyls A and B (1 and 2 ), along with four known biphenyl derivatives (3-6) . Structural elucidations of 1 and 2 were performed by spectral methods such as 1D and 2D NMR spectroscopy, in addition to high resolution mass spectrometry. Compounds 1 and 2 were also evaluated for their anti-tobacco mosaic virus (Anti-TMV) activity. The results showed that compound s 1 and 2 showed high anti-TMV activit ies with inhibition rate s of 25.4 % and 28.3%, respectively, which is close d to that of Ningnanmycin ( 3 3.5 %).
