Volatile compounds in some Lavandula L. plants ethanol extracts

Genetic origin has a significant effect on the composition of biologically active substances in plants. The methods of these substances extracting from raw biomass are also important. Thus, it is actually to study peculiarities of the volatile compounds transition in some lavandin forms to the ethanol extracts in order to determine the trends of their further practical use. Comparative description of the volatile compounds qualitative and quantitative composition in the ethanol extracts of promising lavandin forms and their parental forms are presented in the article. The content of volatile substances in the extracts of Lavandula angustifolia Mill. inflorescences was significantly less than in the extracts of L. x intermedia Emeric ex Loisel. (lavandin) and L. latifolia Med. The maximum concentration of volatile substances was found in the extract of the amphidiploid lavandin. Extract of the L. angustifolia leaves stood out among the other studied samples with a high content of linalyl acetate, linalool and trace amounts of camphor. The main components of the L. latifolia extract were linalool, camphor and 1,8-cineole. Monoterpene esters in this extract were present in trace amounts. The extract of lavandin allotriploid differed from amphidiploid lavandin one by a high content of monoterpene esters, including linalyl acetate (29,02%) and a low total content of camphor and 1,8-cineol. The extract of lavandin allotriploid is promising for use in cosmetic and perfumery industries.
