Malondialdehyde, a product of lipid peroxidation, is often used as an indicator to detect the oxidative stress damaged in the body. Lipidperoxidation is associated with progression of atherosclerosis. It is known that onion (Allium ascalonicum L.) can be used as an antioxidantand hypolipidemic agent, but whether onion can decrease hypercolesterolemia mice MDA plasma induced by yolk is still unknown. Thepurpose of this study was to investigate the effect of onion’s juice on hypercolesterolemia mice MDA plasma level. This was an experimentallaboratory research with post test only design with control. The measured parameters were cholesterol and MDA level on tested groups.Groups with treatment consist of yolks group, and 80% shallot juice, simvastatin and aquadest were separately used as positive and negativecontrol. The result showed that there was significant difference between high fat feed group which added 80% onion’s juice and high fat feedgroup only. Addition of 80% onion’s juice in high fat feed groups decreased MDA plasma level equal to normal feed group. In conclusion, itwas proved that onion’s juice decreased mice MDA plasma level.

Apigenin is one of active component in Celeryleaf that has fungicidal activity, so celery leaf’s extortion suspected has fungicidal activity to Candida albicans. Apigenincan solved in water. The aim of this research was to know antifungal activity of celery leaf’s extortion againsts Candidaalbicans in vitro.This is a laboratory experimental research by using completely randomized design and disc diffusion method. Celeryleaf’s extortion was divided into 3 concentrations, there were 25%, 50% and 100%. Ketoconazole 2% was used aspositive control and aquadest as negative control. The result of this research was based on analysis of variance, therewas significant difference between minimal 2 treatment (p=0.000) and confirmed with Post Hoc test, there were significantdifference in all treatments. As the conclusion, celery leaf’s extortion had antifungal activity againsts Candida albicansin vitro with the best concentration 50% but smaller than ketoconazole 2%.

Dengue Hemorrhagic Fever is caused by dengue virus and spread by Aedes aegypti as primarily vector. Preventingdengue virus transmission depends on control of the mosquito vectors. Kiffer lime is one of the potential plants as abotanical larvacidal. The aim of this study was to investigate kiffer lime larvacidal ability against Ae.aegypti larvaebased on LC50 and LC90 levels by probit analize. The design of this research was experimental including preliminarytest and final test. 525 samples of Ae.aegypti larvae instar III/IV were used in this study and divided in to six groupsof experiment. The result were from observation of the larvae mortalities within 24 hours. Assassement of larvacidalefficacy demonstrated that kiffer lime leaf were toxic against Ae.aegypti larvae. LC50 value is 4015,880 ppm and LC90value is 6961,822 ppm. Ethanol extract of kiffer lime leaf could be considered as a potentially alternative source forbotanical larvacides.
