Plants Mixture Approach: Effect of extraction methods on Polyphenolic Content of Some Medicinal Plants Used against Oral Disorder



On the basis of an ethnobotanical survey with herbalists, who cites plants in a mixed way against dental disorders, comes the idea of this article, for tests of total phenolic compounds the colorimetric method Folin-Ciocalteu, for flavonoids content the standard catechin and for condensed tannins the acidified vanillin was used.

Three methods were also used for crude extractions; namely: infusion, decoction and Soxhlet techniques, the results were statistically analyzed and different correlations between samples and the inter samples were made; the results showed the antagonistic effect in these mixtures where their content decreases compared to plants alone, the phenolic profitability is observed in the mixtures containing less plants extracted by Soxhlet, contrary to the flavonoic compounds which are more in the mixtures containing more plants where their profitability is proportionally related to the extraction by infusion, but at condensed tannins level a specific plant in a specific mixture which can be richer in these compounds, the different correlations have approached these results which can be the object of a more interesting study at the level of the chemical reactions which is carried out from one family to another and from mixture to another.
