The invention relates to the chemical and pharmaceutical industry and to a method for the identification of medicinal plant substances - rose hips and vitamin collection № 1 by analyzing the spectral characteristics of alcohol extraction. The method of identification of hips and vitamin collection № 1 includes obtaining alcoholic extract using ethanol with a concentration of 95%, an aliquot of 5-8 ml is placed in a 25 ml volumetric flask, add 5-8 ml of acetic acid 30%, 8 ml of alcohol 2% solution of aluminum chloride, bring 95% ethanol to the mark (pH of the solution 1.6 ± 0.4) and remove the spectrum against the background of a reference solution consisting of 5-8 ml of alcohol extraction and 8 ml of acetic acid 30% brought to the mark 95% ethanol; at the same time, three absorption maxima are simultaneously detected on the absorption spectrum, corresponding to: phenol carboxylic acids at 311 nm for vitamin collection № 1 and 323 nm for rose hips; flavonoids at 411 nm for vitamin collection № 1 and 404 nm for rose hips; anthocyanins at 540 nm for vitamin collection № 1 and 526 nm for rosehips.
