Phytochemical Study And Extraction Of Total Flavonoids In The Aerial Parts Of Calendula Suffruitcosa Vahl., North East Algeria
In the valuation of the flora in the Northeast region of Algeria, we proposed to the phytochemical study of the aerial parts of a spontaneous plant Calendula suffruticosa VAHL.
Calendula suffruticosa is a plant belongs to the Asteraceae family. The genus Calendula is used in traditional medicine for a long time in the treatment of skin diseases, wounds, burns, dysmenorrhea and duodenal ulcers1.
The phytochemical characterization tests on the brewed, pickled and the powder Calendula suffruticosa VAHL.. The solvents we used for the liquid- Liquid partition are: ethyl acetate and 1-butanol.
The phytochemical screening performed on the aerial organs Calendula suffruticosa VHAL, revealed the richness of the plant by secondary metabolites such as flavonoids3, catechin tannins, sterols, triterpenes, coumarins, alkaloids and saponosides. on the other hand we have noticed the absence of cardinolides, leuco anthocyans, quinones and starch in all parts of the plant (leaf and stem)2.
Yields of extracts made on different parts of the plant (leaves and stems) are relatively large. For the crude extracts, the leaves have the highest yield with 60%. The results obtained for the combined butanol extracts show that the highest efficiency is that of the leaf extract of Calendula suffruticosa VHAL. (74%) followed by the rods (48%). However we noticed that the yield of dry extract of the ethyl acetate fraction of the stems is the one with the highest (38%) compared to that of the stems that gave a very low yield (11%).
