Eugenol has been identified as the major volatile chemical component in clove [4,10]. The antioxidant activity of a commercial rectified clove leaf essential oil (Eugenia caryophyllus) and its main constituent eugenol was tested. The total antioxidant capacity and phenolics content of the 26 spice extracts sought to identify the major phytochemicals present to establish a relationship between antioxidant activity and phenolic content, and thereby confirm the source of this activity. showed efficient antioxidant activity. The housefly is an important resource insect and the housefly larvae are ideal source of food additives. Eugenol (4-allyl-2-methoxyphenol), a major phenolic component from clove oil (Eugenia caryophyllata), has several biological activities.To estimate the capacity of eugenol to act as an antioxidant, the following were studied: 1,1-diphenyl-2-picryl-hydrazyl-, 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid)-, and N,N-dimethyl-p-phenylenediamine-scavenging activity; total . The IC50 of CEO was Clove (Syzygium aromaticum L.) is one type of spice plant that has high antioxidant content because of the high eugenol compounds. Total antioxidant activity of clove volatile oil was also higher than star anise volatile oil. Clove showed to be most effective than sage and rosemary, being ginger and thyme the weakest. The present study was a potential application of Clove Essential Oil (CEO) in industrial fresh double cream cheese in order to lengthen its conservation and to improve its antioxidant potential. Past studies have found that clove oil has diverse uses in the pharmaceutical field due to its antioxidant, antibacterial and anesthetic properties. Their antioxidant activity is credited with slowing down the decomposition of foods, making it a natural preservative. The main products of clove are: whole or ground clove buds, essential oils (produced from clove buds, stem and leaf) and oleoresins. Abstract Eugenol (4-allyl-2-methoxyphenol), a major phenolic component from clove oil (Eugenia caryophyllata), has several biological activities. Clove essential oil was encapsulated by the kneading method with hydroxypropyl beta-cyclodextrin in a 1:1 molecular ratio. Clove mistletoe leaf extracts have many biological activities such as antibacterial, antioxidant and antidiabetes. the Loranthaceae family. II. Antioxidant activity of clove leaf was investigated.
