The genus Actinidia, native to the temperate eastern Аsiа, contains about 80 species. Many species of this genus have interes for pharmacy, food, green space ornamentation and cosmetics. Plant products collected from 3 species – A. kolomikta (Rupr. & Maxim), A. argura (Siebold & Zucc.) Planchand and A. deliciosa (A. Chev.) C.F. Liang & A.R. Ferguson, which were introduced into the plant collection of the Alexandru Ciobotaru National Botanical Garden were subjected to phytochemical analysis, including tannin content. Objective of the study was the determination of tannin content in different vegetal products collected from 3 species of genus Actinidia, grown in climate conditions of the Republic of Moldova. Tannin dosing was performed by titrimetric method in different plant products – Radices, Cortex, Folia and Fructus of A. kolomikta, A. argura and A. deliciosa species. Content was expressed as % FW. The experimental data, obtained in 3 replicates, show that all the products analyzed contain tannins, but the content varies from 0.575 to 11.361% depending on the type of plant product and species. The highest tannin values were recorded for juvenile vegetal products of Cortex (11.361%) and Folia (8.563%) from species A. kolomikta. For the other vegetal products such as mature leaves, roots, mature bark, fruits of A. kolomikta as well as the other 2 species A. arguta and A. deliciosa the tannin content ranged between 0.575 and 2.403%. From all plant products (Radices, Cortex, Folia, Fructus) analyzed from 3 species of Actinidia (A. kolomikta, A. arguta and A. deliciosa), grown in the climate conditions of the Republic of Moldova, the juvenile leaves and bark of A. kolomikta species were found to have a high tannin content, which can be used for pharmaceutical purposes.
