摘要

The present invention relates to a novel neolignan (NEOLASA-I) 3-ethyl-2-methyl-3-(2″, 4″, 5″-trimethoxy-phenyl-1-(2′,4′,5′-trimethoxy) phenyl-1-(2′,4′,5′-trimethoxy)phenyl-1-propene and a process for the preparation of high purity, higher yield neolignan, &agr;-asarone, 2,4,5-trimethoxy-phenyl propionone from &bgr;-asarone or &bgr;-asarone rich Acorus calamus oil containing &agr; and &ggr;-asarone by hydrogenating and dimerizing by treatment with DDQ in presence of an organic acid.
