Sea buckthorn (Hippophae rhamnoides L.) fruits are a valuable source of biologically active substances. Anthocyans, the content of which is not standardized, are present in the sea buckthorn fruits. The authors developed and validated a procedure for the spectrophotometric quantification of the sum of anthocyans in the sea buckthorn fruits, calculated with reference to cyanidin-3-O-glucoside. Optimal conditions for the extraction of anthocyans from the sea buckthorn fruits were determined. The impact of a raw material/reagent ratio, the temperature and frequency of extraction and polarity of a reagent, as well as the impact of the optimal time of extraction of anthocyans to yield were studied. The content of anthocyans in the fruits on drying was established to considerably decrease and amount to less than 30% of the fresh raw material. The validation characteristics of the developed procedure were identified, according to which the latter was valid and suitable for standardization.
