Abstract
A procedure has been developed for the spectrophotometric quantitative determination of flavonoids in rose hips after complex-formation with aluminum chloride. The amounts of flavonoids in the raw material of roses growing in the Western Pamir have been determined as a function of the height above sea level. It has been shown that the flavonoids are distributed nonuniformly in different parts of the rose hip: The greatest accumulation of flavonoids is found in the hairs and the smallest amount in the seeds.
