Abstract:Two crystalline substances were isolated from the petroleum ether extract of the herbal medicine Lysimachia fortunei: triacontanol and a mixture of the derivatives of the pigment 2,5-dihydroxyl-3-alkyl benzoquinone. Mass spectral examination of this pigment revealed the presence of embelin and its five homologues, of which three homologues possessing dodecane, tetradecane and hexadecane respectively in the alkyl side chain have not been reported so far.
