Composition chimique et évaluation de l’activité antioxydante du miel

Abstract

Honey is a complex substance made by bees from nectars or honeydew gleaned. This complex product, extremely rich in chemical composition, has many therapeutic properties that have been demonstrated by several scientific journals. Our work aims to study the antioxidant activity, to determine some physicochemical characteristics as well as the botanical origin of the nine samples of honey from different regions of Algeria, namely Bejaia, Sétif and Laghouat. The pollen analysis shows that most of the honeys are unifloral. The moisture content of the samples falls within the standards of codex alimentarius (<20%). The electrical conductivity is from 0.292 mS/cm to 0.937 mS/cm. The results recorded in polyphenols are from 39.5 to 128 mg EAG/100g of honey, for flavonoids their levels are between 0.95 to 10.7 mg EQ/100g of honey. The study of the antioxidant activity revealed that the samples analyzed have different antioxidant capacities from one honey to another. This test is carried out by two methods, the antiradical activity (DPPH) and reducing power. With the little means and time at our disposal we were able to reveal one of its many miraculous virtues, which is the antioxidant activity
