摘要：

Strobilanthes A (1), a novel isocoumarin with an unusual tetrahydro-4 H-pyran-4-one moiety fused isocoumarin core skeleton, together with a known compound (2) was isolated from Strobilanthes cusia. Its chemical structures were elucidated by 2D NMR spectroscopy, mass spectrometry and single-crystal X-ray diffraction analysis. The biosynthetic pathway of 1 could be supposed to be originally derived from 3-methylisocoumarin, a product of AA-MA pathway. Both of two compounds displayed anti-influenza virus activity in vitro.
