Journal Title: Plant varieties studying and protection - Year 2018, Vol 14, Issue 4
Abstract
Рurpose. The determination of the quantitative and qualitative content of higher fatty acids, aminoacids, macro- and migroelements in Actinidia arguta (Siebold et Zucc.) Planch. ex Miq) seeds. Methods. The qualitative and quantitative composition of higher fatty acids (HFA) was determined on a chromatograph “HP-6890”. The standard set of HFA was used to identify them. The quantitative and qualitative content of aminoacids in actinidia seeds was determined by ion exchange liquid-column chromatography method with an automatic aminoacid analyzer T339 (Czech Republic). The investigation of seeds mineral composition of was carried out using an “ELVAX-MET” X-ray fluorescence analyzer. Results. The content of biological active compounds of A. arguta seeds of ‘Kyivska krupnoplidna’ cultivar was determined. It was revealed that actinidia seeds contain a significant amount of fatty oils (34.9±0.55% based on dry weight). Almost 90% of the total fatty acid content is unsaturated fatty acids – linolenic (64.55%), linoleic (9.96%) and oleic (15.4%). The qualitative composition of the aminoacids of actinidia seeds is represented by 19 compounds (7 essential: valine, leucine, isoleucine, threonine, lysine, methionine, phenylalanine and 12 replaceable) with a total content of 15731 mg/100 g of dry weight. The highest content among the replaceable amino acids was determined for monoamino-dicarboxylic acids-aspartic and glutamic with a content of respectively 2060 mg/100 g and 424 mg/100 g. As a result of the study of the elemental composition of actinidia seeds by the X-ray fluorescence method 14 macro- and microelements were found, the main of which are potassium, calcium, sulfur, iron and zinc. Conclusions. The A. arguta seeds are a valuable source of biologically active substances and may be considered as a promising raw material for the creation of therapeutic and prophylactic products and phytopreparations in the pharmaceutical, food and perfume industry.
