The physico-chemical results obtained show that the Mostaganem sample is marked by a high ash content1.34percentage. On the other hand, the Relizane sample is marked by its high moisture content of 13.10 g/100. The highest level of polyphenols is found in Mostaganem extract (11.65Amg EAG/g of extract) and in tannins (1.30 mg EAC/g extract). Relizane extract is shown to have the highest flavonoid content (9.421 mg EQ/g extract).
