Study the composition of flavonoids fruits of sea buckthorn

Abstract

Wild plants attract the attention of researchers because of their prospects in the manufacture of a
medicament of a wide spectrum of action. They are a rich source of biologically active substances such as
flavonoids, derivatives dihydroxyсoriches acids, iridoids, and other carotenoids. Fruits of sea buckthorn studied
in detail as a source of carotenoids and fatty oils. At the same time, relatively little is known about the
content and composition of flavonoids in fresh and dried fruit of sea buckthorn, which does not allow to evaluate
the contribution of this class of biologically active substances in the total biological activity of preparations
based on fruit sea buckthorn.
The content and profile of flavonoids of sea buckthorn fruits was investigated by using HPLC-DADMS/TOF,
TLC and differential spectrophotometry. The flavonolglycosides derivatives of quercetin, kaempferol
and isorhamnetin were found as the main flavonoids of sea buckthorn . The quercetin-3-rutinoside-7-
glucuronide was identified in sea buckthorn fruits for the first time.
