摘要：

The isolation of (S)-(-)-2,3-dihydro-2,6-dimethyl-4H-benzopyran-4-one (1) from the essential oil produced by natural roots and also from genetically transformed (''hairy'') root cultures of Leontopodium alpinum is described. This is the first reported natural occurrence of 1. Structural assignments were made on the basis of spectroscopic data and by comparison with a synthetic sample.
