Abstract
Two new chalcones, podocarchalcones A and B (1 and 2), together with five known chalcones (3–7), were isolated from the whole plants of Desmodium podocarpum. All of their structures were determined by spectroscopic methods including 1D and 2D NMR. Compounds 1–7 were evaluated for their anti-tobacco mosaic virus (anti-TMV) activity, and they exhibited activity with inhibition rates in the range of 15.2–22.4%, respectively.
