Abstract:
Three new benzolactones (1 – 3), together with four known ones (4 – 7), were isolated from the whole herb of Lavandula angustifolia . Their structures were established on the basis of detailed spectroscopic analysis (1D- and 2D-NMR, HRESIMS, UV, and IR) and comparison with data reported in the literature. New compounds were evaluated for their anti-tobacco mosaic virus (TMV) activities and cytotoxic activities. The results revealed that compounds 1 – 3 showed obvious anti-TMV activities with inhibition rates of 26.9, 30.2, and 28.4%, which were at the same grade as positive control. Compounds 1 – 3 also showed weak inhibitory activities against some tested human tumor cell lines with IC ₅₀ values in the range of 32.1–7.6 μM.
