Abstract

Kinetic studies effectiveness clove leaf (Syzigium aromaticum) oil as antifungal Candida albicans have been done. The study have purpose to determine the reaction order, reaction constants (k) and relationship the concentration of clove leaf (Syzigium aromaticum) oil every time (At) with the initial concentration of of clove (Syzigium aromaticum) oil (Ao) and time (t) and equipped determination of the minimum concentration of clove leaf (Syzigium aromaticum)oil effective anti-fungus Candida albicans. The results shows the anti-fungal activity clove leaf (Syzigium aromaticum) oil on Candida albicans for each variation of the concentration 100%, 75%, 50% and 25% are 14.2 mm, 12.2 mm, 10.8 mm and 10.4 mm respectively. Reaction order as antifungal of the clove leaf (Syzigium aromaticum) oil on Candida albicans is 0.2112 with k = 5.0594. The minimum concentration of clove leaf (Syzigium aromaticum) oil as anti-fungal Candida albicans is 17.86%.

Abstract

Cleome viscosa L. has been used empirically by people on the island to treat diseases that have clinical symptoms such as malaria (fever, sweating, chills, and muscle aches). The purpose of this study was to determine the class of secondary metabolites and antioxidant activity. The extraction was carried out using the maceration method, while the fractionation was carried out using the separating funnel. The secondary metabolites found in the Cleome viscosa L. plant extract are alkaloids, flavonoids, steroids, terpenoids, tannins, and saponins. Antioxidant test conducted by DPPH method showed that the positive control of ascorbic acid and methanol extract obtained IC50 values of 3.86 ppm and 37.4 ppm, respectively.
