Abstract

Durian fruit already famous enough in Indonesian society. Not only the content of the fruit, but Durian also have many advantage for example the seed, leather, root and the leaves that useful for human healthy. Then, phytochemical screening test and antioxidant activity test. Antioxidant activity test use scavenging test to 2,2-diphenyl-1-picryhidrazil (DPPH) radical. On antioxidant activity test, mix of extract and DPPH are incubate for 30 minutes, then the absorbance is measured on λ = 514 nm using spectrophotometer. The absorbance from sample, blank, and negative control are converted as Antioxidant Activity Absorbance (AA%). Based on result of phytochemical ethanol extract, Durian steud contain of fenolic, flavonoid, alkaloid, and tryterpenoid. Based on antioxidant activity test with DPPH radical scavenging method by spectrophotometer. Ethanol extract of Durian has antioxidant activity about EC 50 23,10 μg/mL and Vitamin C as comparison has antioxidant about EC 50 3,76 μg/mL.

Phytochemical tests, mortality of larvae shrimp (brine shrimp lethality test) and the antibacterial activity of theleaf merkubung (Macaranga gigantea Rchb.f. & Zoll.) With various factions has been conducted. Merkubung leafsamples were extracted with ethanol and concentrated by using rotary evaporator. The total extract was fractionatedwith n-hexane and ethyl acetate. The results of phytochemical compounds secondary metabolites merkubung leavesshowed that the total extract are contains alkaloids, phenolics and steroids. n-hexane fraction are containing alkaloids,flavonoids and steroids. Ethyl acetate faction are containing flavonoids and steroids. Ethanol-water faction is containingphenolic compounds. Shrimp larvae mortality trials showed mortality rates of larvae of Artemia salina (L) by usingSAS Probit analysis to determine the value of Lethal Concentration 50 % (LC50). The test shows that the most toxicfraction is the total extract with LC50 values of 459.8414 ppm. The test of antibacterial activity using paper disc methodand shows that the most active faction is the total extract with a MIC (Minimmum Inhibitor Concentration) of 1 % is6.5 mm diameter clear zone on Staphylococcus aureus (Gram positive) and 6.25 mm in the bacterium Escherichia coli(Gram negativ).Keywords : Macaranga gigantea Rchb.f. & Zoll., phytochemical test, Antibacteria activity test, LC50.

Abstract

Research on phytochemical test and toxicity tests of leaf extract of Gliricidia (Gliricidia sepium) as an insecticide plant have been conducted.. Gliricidia leaves macerated dried samples using ethanol and fractionated using a solvent n-hexane and ethyl acetate. Phytochemical test showed that it contains alkaloids, steroids, triterpenoids, phenolic and flavonoid in total extract. N-hexane fraction containing steroids, triterpenoids and the phenolic. Ethyl acetate fraction containing steroids, triterpenoids, flavonoids, phenolic and saponin. Toxicity test method Brine Shrimp Lethality Test (BSLT) showed that the ethyl acetate fraction had the highest toxicity on shrimp larvae with LC50 values ​​of 49.29 ppm. Test Activity as an insecticide plant conducted in animal infestation of rice (Sitophylusorizae Leach) Value LC50 is determined using a regression line between log concentration and probit mortality, the LC50 obtained is 2.831%. Analysis of the content of chemical compounds in the ethyl acetate fraction from the leaves of Gliricidia produces 9 peak component compounds at mass spectra are shown from the results of GC-MS with 2 peaks compound dominant that serves as an insecticide plant them 2-(3H)-Benzofuranone, 3-methyl and dl-Limonene
