Abstract

This study aims to determine the antibacterial activity of essential oils and residue fromthe distillation of Sintok bark (C. sintoc Blume) against S. aureus bacteria. The researchwas carried out by distillation of sintok bark and macerating the dregs. Furthermore, theessential oil and extract the dregs were tested for antibacterial activity against S. aureus.Inhibition zone data were tabulated and analyzed by simple linear regression. The resultsshowed that the essential oil with the highest inhibition zone at a concentration of 20,000mg / L was 11.10 mm, As well as the inhibition zone dregs extract of 6.57 mm. Inconclusion, sintok wood essential oil is more active than its pulp against S. aureus. Inconclusion, sintuk wood essential oil is more active than the dregs extract against S.aureusKeywords : Antibacterial, essential oil, Cinnamomum sintoc, Staphyloccocus aureus

Abstract

Tujuan penelitian untuk mengetahui aktivitas toksisitas minyak atsiri kulit kayu sintok (C. sintoc Blume) kondisi segar dan kering terhadap larva A. salina Leach. Menggunakan metode destilasi kulit kayu untuk mendapatkan minyak atsirinya, kemudian diuji toksisitasnya dengan larva menggunakan metode Brine Shrimp Lethality Test (BSLT), analisis senyawa menggunakan GC-MS. Kematian larva dianalisis dengan Regresi Probit. Hasil penelitian menunjukkan, minyak atsiri kulit kayu segar dan kering bersifat toksik. Minyak atsiri kulit kayu segar mengandung 11 senyawa, dan Minyak atsiri kulit kayu kering mengandung 13 senyawa. Diduga senyawa yang terkandung pada minyak atsiri kulit kayu C. sintoc Blume segar dan kering yang menyebabkan kematian larva A. salina Leach

Abstract

The objectives of this research were to evaluate the extractive substances of heartwood of Kupa wood (Syzygium polycephalum (Mig)) and its potention as bio-active substance to wood destroying fungi i.e., Schizophyllum commune Fr and Pleurotus sp. Successive extraction method was used in this experiment. The heartwood part was then converted into 40 mesh wood flour and followed by extraction using methanol, chloroform, ethyl acetate, n-hexane and buthanol solvents. The extractives obtained were subjected to wood destroying fungi S. commune and Pleurotus sp. The results indicated that the extractive content of S. polychephalum mostly dominated by substance diluted in chloroform (2.87%), followed by ethyl acetate (0.38%), n-hexane (0.33%) and buthanol (0.05%). All the wood extracts of S. polychephalum potentially contain anti-fungal compound to inhibit the growth of S. commune Fr and Pleurotus sp fungi. N-hexane and ethyl acetate extracts of S. polychephalum are the most active extracts. Isolation of ethyl acetate fraction resulted in nine (9) active compounds (G.1-G.9) that could inhibit the growth both S. commune and Pleurotus sp with IC(50) values 49.33-61.71 ppm and 48.84-64.61 ppm, respectively. It was found that G.2 compound of ethyl acetate has anti fungal substance namely 3-O-glucosyl-3’,4’ 5-trihydroxyflavonol.

Abstract

The objectives of this research were to evaluate the extractive substances of heartwood of palepek baringin wood (Shorea leavis Ridl) as a bio-active substance to wood destroying fungi i.e. Schizophyllum commune Fr and Pleurotus ostreatus. The 40 mesh of heartwood meals was extracted by methanol, chloroform, ethyl acetate, n-hexane and buthanol. The extractives obtained were subjected to wood destroying fungi S. commune and P. ostreatus, and preservative containing copper, chrome and boron (CCB) was used for comparison. The extractive of palepek baringin wood was dominated by ethylacetate fraction (3.54%), followed by chloroform and butanol fraction 1.73% and n-hexane (0.09%). All fractions have an antifungal activity to inhibit the growth of S. commune and P. ostreatus. Concentration of 50 ppm butanol fraction inhibited the growth of S. commune, and concentration of 250 ppm chloroform fraction inhited the growth of Pleurotus sp. Preservative of CCB 100 ppm inhibited the growth of S. commune and P. ostreatus by 43%. Butanol fraction contained 16 active compounds (PB.1-PB.16) that could inhibit the growth both of S. commune and P. ostreatus with IC50 54.29-64.32 and 48.40-65.86 ppm, respectively. Based on mass spectrometry (LC-MS) and 1HNMR analysis, the compound of PB.1.1 which has anti-fungal activity was 2,3-dihydroxyoctadecanoic acid.Key words: 2,3-dihydroxyoctadecanoic acid, antifungal, Pleurotus ostreatus, Schyzophlum commune, Shorea leavis
