Study of chemical composition of Persica davidiana Carr. leaves during vegetation

Abstract

Changes in content of dry substances, pectins, organic acids, ascorbic acid, carotenes, phenolic substances (catechines, leucoantocianines, flavonols) in Persica davidiana Carr. leaves during the vegetation process have been studied. It was established that the studied indices are similar to the analogical ones in other representatives of genus Persica Mill. (P. vulgaris and P. vulgaris subsp. nectarina) with lower meanings of carotene and higher meanings of leucoantocianines. The highest indices values in P. davidiana leaves were revealed in June (contents of ascorbic acid, combined and titered acids, water soluble pectin), July (contents of carotene, catechins, leucoanthocyanins), August (content of protopectin, flavonols) and October (dry substances content).
