Study of the correlation between the content of polyphenols in different combinations of plant extracts and their antioxidant activity of a multicomponent herbal medicine with antiallergic effect
Combinations of medicinal plants ensure the collective work of several active components, which can lead to an additive or synergistic effect. We have chosen the bur-marigold-calendula-hawthorn combination to obtain an antiallergic herbal medicine, in which the bur-marigold is the main plant, calendula is a helper plant that helps in the fight against accompanying symptoms, and hawthorn harmonizes the action of the first 2 plants. The aim of the work – the study of possible synergistic interactions in a multicomponent herbal antiallergic preparation by calculating the correlation between the content of polyphenols in various combinations of plant extracts and their antioxidant activity. Both individual extracts of a bur-marigold herb, calendula flowers and hawthorn leaves and flowers and a combined target extract with the ratio of herbal drugs (6:3:1) were obtained. Two and three component ompositions were obtained by mixing extracts in appropriate ratios. The content of polyphenols was determined by SPhU 2.0, 2.8.14. The antioxidant activity was determined by the neocuproin method. The Pearson Correlation was used to calculate the relationship between the content of polyphenols in extracts and their antioxidant activity. The maximum amount of polyphenols was found in the hawthorn extract (7.2%), in the bur-marigolg extract – 5.5%, and in the calendula extract – 3.4%. When adding calendula extract to the bur-marigold extract, the antioxidant activity was expected to decrease, thus an additive effect is observed; for the combination of bur-marigold /hawthorn 1:0.5, an increase in antioxidant activity (110.6%) was observed compared to the expected value, which may be synergism; for the combination of calendula/hawthorn, an increase in activity was observed. For 3-component combinations, it was found that only the combination of bur-marigold/calendula/hawthorn 1:0.5:0.5 showed greater activity (112%) than the target extract, all others combinations showed activity within the limits of possible variations (± 10%) of the components. When calculating the correlation between the content of polyphenols in the combinations and their activity using the Pearson coefficient, a strong positive correlation was found. The correlation between the content of polyphenols in various combinations of plant extracts and their antioxidant activity of a multicomponent herbal antiallergic preparation was studied. In 2-component combinations an additive effect was found when determining antioxidant activity, and an assumption was made about the ability of a synergism only for a combination of bur-marigold/hawthorn 1:0.5. All analyzed 3-component compositions showed antioxidant activity within the limits of possible variations (± 10%) of the components. A strong positive correlation was found between the content of polyphenols in the combinations and their activity..
