                  The fruits of actinidia are new fruits on the market and are in increasing demand from
            consumers all over the world. In this regard, it is important to identify the benefits of the
            fruits of actinidia for human health.
                  The purpose of the study was a comparative study of cultivars of Actinidia kolomikta in
            the content of soluble solids in the fruits, antioxidant activity, gallic, chlorogenic acids, ash
            composition and the presence of low molecular weight metabolites.
                  The objects of research were 10 cultivars from the collection of  Actinidia  kolomikta
            (Maxim. & Rupr.) Maxim. (FSTU): Vinogradnaya, Dolgovechnaya, Nadeghda, Pamyati
            Kolbasinoj, Prazdnichnaya, Prelesestnaya, Sеstrа, Uslada, Chempion, Ella. The studies were
            performed      using    the    following    methods:     refractometric,    spectrophotometric,
            chromatographic (high-performance liquid chromatography HPLC, gas chromatographic mass
            spectrometry-GHMS) and energy dispersive (EMF analysis).
                  The content of soluble solids in the fruits of Actinidia kolomikta ranged from 12.6 (cv.
            Vinogradnaya,) to 19.9 % (cv. Sestra). Antioxidant activity of  alcoholic extracts is 1.3–2.2
            times higher than water. The minimum antioxidant was found in the Nadeghda cultivar (89.5
            and 40.2 %), the maximum in the Pamyati Kolbasinoj cultivar (93.1 and 73.3 %) alcohol and
            aqueous extracts, respectively. The content of gallic acid in the test samples did not exceed
            0.01 mg/%; chlorogenic acid content is on average 2.3 times higher than gallic. The ash
            composition is represented by 12 elements, the series of which decreases is:
            K≈Ca>P≈Mg>Mo>S> Se> Zn≈Si>Co≈Fe>Na. The content of elements in the ash is: K and Ca –
            10.1–23.5; P and Mg – 1.1–5.5; Mo – 0.4–1.8; S  – 0.3–0.9; Se – 0.2–0.4; the share of the
            remaining elements does not exceed 0.015 mass%, respectively.
                  In water extracts from fresh fruits using the NIST spectra database 36 low molecular
            weight metabolites were identified: 8 organic acids (ascorbic, malic, citric and isolimone,
            valeric, dodecanedicarboxylic, ribonic, tartaric); 7 substances of phenolic nature –  вenzoic
            acid,  рhenylacetic acid, natural phenolic antioxidant Tirosol,  рhthalic acid, anisic acid,
            сinnamic acid, myo-inositol; 6 sugars – glucose, mannose, xylose, ribose, tagatose, sorbitol; 6
            furanose and pyranose forms of monosaccharides – ribofuranoside, fructofuranoside,
            glucofuranoside, xylopyranose, tagatofuranose, thalopyranose; 7 organic acids that make up
            the oils – lauric, myristic, pentadecanoic, palmitic, octadecanoic, linoleic, stearic; 2 amino
            acids – l-alanine and betaine (a derivative of glycine).
                  All substances found by us limit the nutritional value of the fruits of Actinidia kolomikta.
            Our research convincingly shows that the fruits of the cultivars of the uncommon culture of
            Actinidia  kolomikta,  cultivated in the conditions of the Moscow region, are an excellent
            component of the composition of dietary functional foods.
