An antifungal substance was isolated from the extract of Acorus gramineus using various chromatographic procedures. The antibiotic was identified as beta-asarone, cis-2,4,5-trimethoxy-1-propenylbenzene, on the basis of the high-resolution EI-mass, NMR, and UV spectral data. Beta-asarone completely inhibited mycelial growth of

Oxidation of beta-asarone (2) with DDQ gave trans-2,4,5-trimethoxycinnamaldehyde (3), which on treatment with p-toluenesulfonyl hydrazine provided corresponding alpha,beta-unsaturated hydrazone derivative (4). Reduction of 4 with sodium borohydride in acetic acid afforded gamma-asarone (1) in 43% yield.
