Abstract

Bay leaf (Syzygium polyanthum(Wight)Walp) is one of the plants used as herbs or spices, used as food flavoring because the leaves have a distinctive aroma. The plant leaves are known to contain flavonoids, alkaloids, steroids, and tannins. Cream both dosage forms semi-solid, in the form of an emulsion of viscous containing not less than 60% water, is used for external use. The purpose of this study is to determine the antioxidant activity of the cream of ethanol extract of bay leaf (Syzygium polyanthum(Wight)Walp) with a made three variations of the concentration of the extract i.e. 3%, 6%, and 9%. Extraction was done by maceration using ethanol 70%, maserat evaporated to obtain a thick extract. Testing the cream of ethanol extract of bay leaves include, test organoleptic, homogeneity test, pH test,Test coverage, test adhesion, viscosity test and stability test. Stability test is performed at a temperature of 4OC for 24 hour and then transferred at a temperature of 40OC, performed a total of 6 cycles. Testing the antioxidant activity by DPPH (1,1-Diphenyl-2-Pycrylhidrazil) is carried out by spectrophotometry. The results showed ethanol extracts of bay leaves and cream ethanol extracts of bay leaves have antioxidant activity. IC50 values ethanol extracts of bay leaves that 42,83 ppm. IC50 values cream ethanol extract of bay leaf 3% that 111,14 ppm, cream of ethanol extract of leaves 6% of 110,42 ppm, and cream of ethanol extract of leaves of 9% which is 109,49 ppm. Ethanol extracts of bay leaves in the category of very strong antioxidant and cream ethanol extracts of bay leaves in the category of modrate antioxidant. Keywords: Bay leaf, antioxidant, DPPH, IC50.
