Description The present invention relates to a process for the preparation of high purity and yield aasarone,
trans 2,4,5-trimethoxy cinnamaldehyde, 2,4,5-trimethoxy-phenyl propionone, from
p-asarone or P-asarone rich Acorus calamus oil containing a and y-asarone by
hydrogenating, followed by treatment with DDQ with or without solid support of silica gel or
alumina in dry organic solvent and a-asarone can also be obtained by treating the
hydrogenated product of P-asarone or P-asarone rich Acorus calamus with DDQ in an
aqueous organic solvent to obtain an intermediate 2,4,5-trimethoxy phenyl propionone,
which in turn is reduced with sodiumborohydride to obtain the corresponding 2,4,5-
trimethoxy-phenyl propanol and followed by final treatment with a dehydrating agent
