Abstract

Aril and seeds of "pala wegio" {Myristica fatua Houtt),as one of endemic plants from Moluccas, contained 0.81% and 0.73%essential oils respectively.Gas Chromatography & Mass Spectrometry (GCMS) analyses indicated two similar major components (>10%) in aril and seeds essential oils of "pala wegio", (-) a-Copaene (aril 36.11% & seeds 29.81%) and caryophyllene (aril 18.05% & seeds 34.62%).However, the seeds essential oil had the third major component unindentified with 17.58% content.

Abstract

This study was done to determine the chemical compounds and antibacterial activity of ki cengkeh (Urophyllum arboreum (Reinw.ex. Bl.) Korth.) essential oil. Ki cengkeh has already known as medicinal plant in some places in Indonesia. This might be correlated with its chemical compounds. The analysis of chemical compounds of ki cengkeh essential oil was done by GC-MS, while antibacterial test was done by paper disc method against 3 bacteria isolates (Staphylococcus aureus, S. epidermidis and Eschericia coli). The result of GC-MS analysis showed that there were 25 compounds with the concentration more than 1% and carryophylen oxide as the highest compound (12.03%). The highest antibacterial activity was found against S. epidermidis.

Abstract

Rutaceae is one of the essential oil resources that is very potential for medicinal, perfumery and other use This study was conducted to analyze the essential oil components resulted from water distillation of kalamanjarik leaves (Micromelum minutum), jeruk \epara leaves ILimnocitrus litoralis) and the leaves and the stem bark of malapotung (Evodia qlabra). The results showed the leaves of kalamanjarik contained approximately 0,70%, jeruk jepara 0,21%, malapotung leaves 0,17% and the stem bark contained 0,50 % essential oils. GCMS analyses of the essential oils gave 3 major components of kalamanjarik leaves i.e /J-pinene (24,41%j, bergamiol (23,01%) and nerolidol (18,90%) and 2 major components of jeruk jepara leaves i.e fl-mircene (70.55) and /t-pinene (24,06 %). Essential oil of malapotung leaves consisted of 39,8J% ct-pinene, 14,26 % 1aR(1aa,4a/3,7a,7aa,7ba)decahydro -1,1,7-lrimethyl-4-methylene-1H-cycloprope azulene and 16,62% S-cadinene as major components, while the stem bark had only one major component, u-pinene (68,37 %) The minor components of the four essential oils will be discussed.

Abstract

Dalam peradaban timur, cendana telah digunakan secara tradisional semenjak 4000 tahun yang Ialu. Minyak atsiri yang diperoleh dari kayu cendana digunakan dalam upacara keagamaan dan sebagai obat-obatan. Dalam kebudayaan barat, cendana hanya digunakan sebagai bahan parfum kelas utama. Bam setelah tahun 1920-an, sejalan dengan perkembangan aromaterapi, bangsa barat mulai memanfaatkan cendana sebagai bahan obat-obatan. Minyak atsiri adalah substansi kimia yang membuat cendana menjadi berharga, baik secara ekonomi, bahan obat dan bahan parfum. Setiap bagian tumbuhan cendana memiliki kandungan minyak atsiri yang bervariasi. Bagian akar memiliki kandungan minyak tertinggi, yaitu 10 %, kemudian diikuti oleh bagian teras batang (4-8 %) dan ranting (2-4 %). Delapan puluh sampai 90% dari minyak cendana terdiri dari senyawa santalol dengan isomer a-santalol dan p-santalol sebagai komponen utama. Dalam perdagangan intemasional, minyak cendana kelas satu haruslah mengandung santalol minimal 90% dari kandungan total minyaknya. Dalam aromaterapi minyak cendana dikenal sebagai salah satu bahan alami yang berkhasiat sebagai sedatif, relaksasi dan mengatasi kasus insomnia serta serangan asma. Laporan terakhir juga menyebutkan bahwa minyak cendana bersifat menghalangi efek karsinogenik dari zat kimia. Alpha-santalol sebagai komponen utama minyak cendana dapat mengurangi kasus papiloma (tumor kulit) sebesar 32 %.

Abstract

Wati(Piper methysticum Forst.f.)leaves has been used as narcotic in some parts of Irian Jaya since longtime ago. The GCMS analysis of wati leaves organic extracts(hexane,chloroform, methanol)has detected 48 components consisted alkanes,oxygenated hydrocarbons, fatty acid, steroids and alkaloids,including 5 major components, i.e. dihydro kawain,anisol p-undecyl, 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-on, levulinic acid and one of unknown component.Forty-three other minor components will be discussed.

Abstract

A study on the influences of alcohol extract of Meniran or Phyllanthus niruri L. (Euphorbiaceae) to blood glucose concentration in rabbits (Oxytolagus cuniculus) had been carried out using glucose tolerance method.The extract was administered orally at 10, 20, 30, 40 and 50 mg/kg BW.Prior to tfie extract administration, all rabbits were put on hyperglycemic condition by injecting glucose solution intravenally at dose of 0.5 g/kg BW.The blood glucose concentration was measured every one hour starting at 2 hours before and until 7 hours after administration. Antidiabetic drug,tolbutamid 250 mg/kgBW.was used as control.The results indicated that extract with dose at 30 mg/kg BW gave a hypoglycemic effect similar to control (Tolbutamid). The blood glucose decreased regularly as the extract dose being higher.Using statistical analyses showed significant differences among the groups, especially after the 2 and 3 hours of treatment (P<0.05).

Abstract

Chemical analysis of leaves essential oil on three Piper species, P. malamiri, P. baccatum and P. majusculum was conducted using gas chromatography and mass spectrometry (GCMS) method.Chromatogram result showed 52, 56 and 47 peaks on leaves essential oil of P.malamiri, P.baccatum and P.majusculum respectively. Based on the peaks,it is known that isocaryofilene is the major, common and as the highest component found in the three essential oils, beside several other major components.

Abstract

A study was conducted in determining the contents of alkaloid, tannin and nutritional Values from six browses fed to fattening cattle in Timor island. The samples Were gmelina (Gmelina arborea Roxb.),pates/lamtoro (Leucaena leucocephala [Lamk.J De Wit),daun kupu-kupu (Bauhinia malabarica Roxb.), gala-galaAuri (Sesbania grandiflora [Li Pers.l gamal (Gliriddia sep/um [lick] Steud.).and kabesak (Acacialeucoohloea Willd.).Samples were collected during wet and dry seasons.Results showed that total number of alkaloid compounds varied from 14 to 30.There was an increase in concentration for alkaloid and tannin from Wet to dry season, however the concentrations were low (< 1%).The increase in the concentrations between seasons Were ranged from 20% to 32096.Nutritional values of the browse during wet season were considered high, however there is a need in evaluating the nutritional values of the browses during dry season as well.
