Flavonoid compounds present in the fruits of Turkestan hawthorn (Crataegus turkestanica A. Pojark), indigenous to the mountainous regions of Uzbekistan, were meticulously examined.

Elevated levels of flavonoids were observed in the pharmaceutical preparations. These findings substantiate the medicinal significance and distinctive composition of this species.
