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.
Keywords: Actinidia kolomikta, fruits, biochemical composition.
