Abstract

The  aim of study were to determine the chemical compounds and peroxide values (POV) of methanol extract of three plants species belongs to Moraceae family (Artocarpus (Artocarpus sp., A.elasticus, dan Ficus sp.). Their chemical compounds were identified by Cuiley method, while peroxide value was done by iodometri titration. Methanol extract percentage of Artocarpus sp., A.elasticus, dan Ficus sp. were 20.80%, 3.10% and 4.10% respectively. All of the extract tested contained essential oil, sterol and triterpenoid, aglicon flavonoid, tannin, flavonoid glicoside and saponin. POV of Artocarpus sp., A.elasticus, dan Ficus sp. were 325.24, 306.25 and 1580.07 respectively and POV of q tocopherol was 363.96. So, it can be concluded taht all of three methanol extract act as reductor, because their POV less that POV of q tocopherol and might be act antioxidant. These correalted with their chemical compounds such as flavonoid, tannin and peroxide sugar.

Abstract

Mbosi (Dysoxylum gaudichandianum (A.Juss) Miq.) belongs to Meliaceae family, Its potential bioactivity had not been known although the other plants from the same family had been known as natural insectiside or medicinal plants. Phytochemical screening showed that mbosi fruit contained fat, fatty acid, sterol, triterpenoide, tannin, peroxide sugar, alkaloid, steroid glycoside and flavonoid. Identification of mbosi fruit chemical compounds by GC-MS showed that it contained 16 compounds. Compounds with the concentration more than 5 % were butyl cellosolve (11.1%), erythritol (8.48%), glycerol (10.32%), hexadecanioc acid palmitinic ester (16.2%), oleic acid (65.3%) and ethyl oleat (6.2%).  In-vitro antibacterial test on innoculated Mueller Hinton Agar to seven bacteria isolates (Salmonella typhimurium, S. typhii, Eschechiria coli ATCC 25923, Pseudomonas sp., Staphylococcus aureus ATCC 25922, S. epidermidis, and Bacilus subtilis)  showed that 20% methanol extract  inhibit only the growth of  Staphylococcus aureus.
