摘要

The present invention relates to neolignan (NEOLASA-I) 3-ethyl-2-methyl-3-(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, α-asarone, 2,4,5-trimethoxy-phenyl propionone from β-asarone or β-asarone rich Acorus calamus oil containing α and γ-asarone by hydrogenating and dimerizing by treatment with DDQ in presence of an organic acid.
