Component composition of crystalline mass obtained from different fractions of roots of Lactuca serriola L.
Summary
A number of species belonging to the Compositae (Asteraceae) family have been shown to be of medical importance in in vitro and in vivo studies. L. serriola, belonging to the genus Lactuca of this family, contains various pharmacologically active substances. This study is devoted to the research of the chemical composition of the roots of L. serriola by Gas-Chromato-Mass Spectrometry (GC-MS) method. As a result, 22 different components were identified from fatty acid esters found in most plant species, including methyl myristate, methyl linoleate, methyl oleate, methyl stearate, hexadecanoic acid methyl ether, and oleic acid and hexadecanoic acid are from fatty acids. In addition, some triterpene compounds (lupeol acetate, germanicol) specific to the L. serriola were also identified. Of the identified substances, those with pharmacological activity are: 2-monoolein, hexadecanoic acid, hexadecanoic acid methyl ester and lupeol acetate. The high content of lupeol acetate and hexadecanoic acid methyl ester as well as the availability of their pharmacological activity puts the respective plant’s medical importance forward.
