Phytochemical study and dosage of polyphenols and flavonoids of the methanolic extract of the leaves and stem bark of Gardenia ternifolia

Gardenia ternifolia is a medicinal plant used in Senegal and several African countries for the treatment of many pathologies. According to results bibliography, four parts plant, mainly purposes, are recommended. Therefore, chemical studies made on extracts leaves, roots, seeds fruits show that they rich sources secondary metabolites. The phytochemical study carried out hexane, ethyl acetate, methanolic aqueous leaves stem bark reveals presence polyphenols, flavonoids, alkaloids, gallic catechin tannins, sterols, polyterpenes, coumarins, mucilages, catechols Leucoanthocyanins two different organs this plant. successive obtained with methanol water gave yields varying respectively from 0.14 3.94% 0.08 1.62% extracts. determination total polyphenols variable contents between 1.57 ± 0.05 7.00 0.044 μg EAG/mg stems. Compared levels vary 15.45 0.066 EQ/mg leaves. In general, extract richest metabolites, flavonoids. This suggests these families compounds responsible biological activity certain types diseases. However, in-depth tests antioxidant, antidiabetic antimicrobial activities necessary order identify full therapeutic potential
