Phytochemical Screening and Antioxidant Activity of essential oil of Eucalyptus leaf

Abstract

A b s t R A c t barks, roots, fruits, buds, leaves and other parts of plant are considered as source of essential aromatic oils to cure several ailments. the antioxidant property has been shown to be important in recovery from several diseases. the essential oil extracted from eucalyptus leaves was tested for phytochemical analysis and antioxidant activities. the eucalyptus oil extracted from the leaves of Eucalyptus globulus family Myrtaceae was screened for the presence of phytochemicals and their effect on 2, 2-Diphenyl-1-picryl-hydrazyl radical (DPPH) and Nitric oxide free radical. Phytochemical screening of the plants showed the presence of flavonoids, terpenoids, saponins and reducing sugars. Eucalyptus globulus is not having any cardiac glycosides and anthraquinones. the free radical scavenging activity of the different concentrations of the leaf oil (10, 20, 40, 60 and 80% (v/v) in DMsO) of E. globulus increased in a concentration dependent fashion. In DPPH method, the oil in 80% (v/v) concentration exhibited 79.55 ± 0.82%. In nitric oxide radical scavenging assay method, it was found that 80% (v/v) concentration exhibited 81.54 ± 0.94% inhibition. It was concluded that leaf oil is potent inhibition of free radicals.

Antioxidant Mechanism of Active Ingredients Separated from Eucalyptus globulus

“…Tables 2 recorded the activity (using DPPH method) which increased by doubling the extract concentration (50 and 100 µg/ml). These results are in agreement with those of Mishra et al [20].…”

“…However, the glycoside and flavonoids content have the lowest value (0.2 and 0.05 % respectively). These results are in agreement with those of Mishra et al [20] who found …”

Chemical profiling of leaf essential oil, Antioxidant potential and Antibacterial activity of Syzygium lanceolatum (Lam.) Wt. & Arn. (Myrtaceae)

“…17 A research work has been carried out to test the antioxidant activities of Eucalyptus globulus (Myrtaceae) and the results showed that the plant is extremely beneficial. 18 The critical review of earlier works proved that the family Myrtaceae is a potential source of natural antioxidants.…”
