Studies on the geometrical isomerism, the synthesis and the antimicrobial effect of the 4-alkenoic acid in the fatty acids from the Lauraceae seed oils

Abstract

In the seed oils from the Lauraceae family plants, e.g. Litsea glauca Sieb [Neolitsea sericea (Blume) Koidz.], Lindera obtusifolia Blume, Lindera citriodora (Sieb. et Zucc.) Hemsl, Neolitsea aciculata (Blume) Koidz., Lindera strychnifolia (Sieb, et Zucc.) F. Vill., and Lindera umbellata Thunb., the characteristic cis—4-aIkenoic acids, such as cis-4-decenoic, cis—4—dodecenoic and cis—4—tetradecenoic acid were found. The methods of isolation, purification, identification of the above mentioned acids, syntheses of cis—and trans—acids and the antiseptic property of cis—4-decenoic and trans—4—decenoic acids and their corresponding sadium salts were reviewed.
