Relevance. Ascorbic acid, which is better known among the population as vitamin C, is often used in the autumn-winter and winter-spring periods, when there is a seasonality of colds, to strengthen immunity and increase the body's resistance to environmental influences. It is part of almost all multivitamin products offered in pharmacy organizations. In addition, it is contained in many types of medicinal plant raw materials such as rowan, viburnum, sea buckthorn, St. John's wort grass, nettle leaves and others. But the most frequently purchased are the rosehip fruits. Therefore, it is important to understand in what quantity and in what raw materials ascorbic acid is contained.
Goal. To determine the quantitative content of ascorbic acid in water extracts of rosehip fruits.
Methods. The objects of research are whole rosehip fruits packed in packs, and fruits crushed in filter bags belonging to different categories of pharmacy assortment (LRS and RS related to dietary supplements), as well as water extracts based on them. Pharmacopoeial methods of obtaining aqueous extracts from LRS were used (GF ed. XIV, vol. 2, OFS.1.4.1.0018.15), determination of humidity (GF ed. XIV, Vol. 2, OFS.1.5.3.0007.15) and the quantitative content of ascorbic acid in rosehip fruits (titration with 2,6-dichlorophenolindophenolate sodium) (GF ed. XIV, Vol. 4, FS.2.5.0106.18).
Results. A study was conducted on the quantitative content of ascorbic acid in rosehip fruits, presented in the pharmacy assortment as medicinal plant raw materials and as a herbal tea belonging to the category of dietary supplements. The degree of shredding of raw materials was also taken into account – whole fruits packed in packs, and fruits crushed in filter bags. It turned out that the plant raw materials related to dietary supplements contain a smaller amount of ascorbic acid, unlike rosehip fruits, which are medicinal plant raw materials, to which strict quality compliance requirements are imposed according to the pharmacopoeia article.
Conclusion. The paper shows that the largest amount of ascorbic acid is contained in the aqueous extracts of rosehip fruits related to LRS, compared with the aqueous extracts obtained from plant raw materials related to dietary supplements.
