Abstract

Antlers are deer’s bony organ that follows a cycle of growing, hardening, casting and regroupingwithin a certain period. The effect of consuming velvet antler from temperate origin has beenknown scientifically to have positive effect for rheumatism and metabolic disorder sickness therapy.However, the role of velvet antler originated from tropical deer has not yet been explored. Thisstudy aimed to assess the potential of the velvet antler of sambar deer (Rusa unicolor) which wasexperimentally fed to laboratory rats. The assessment was made based on the animals growth rate(i.e. femur length, weight of testicle, body eight) and physical endurance (i.e. swimming test).Laboratory rats at 21 days old were allocated into four different groups and each group consisted offive rats were fed with powder of soft and hard parts of velvet antler at dose of 0, 1, 2, and 3 g/kgbody weight, respectively. Animals were examined for eight weeks the body weight was examinedweekly and the dose at velvet antler supplement was adjusted accordingly. At the end of the studythe rat were put on endurance swimming test and then euthanized, for measurement of femurbone length and weight of testis. The results showed that there were no differences in the bodyweight. However at dose of 2 g soft part/kg BW indicating a consistently higher live weight gainsacross the observation time. Testis weight showed no significant differences between the treatments,but the length of femur bone showed a significant effect (p <0.05) with the doses level, with thehighest score being at 3 g hard part / kg BW. Physical endurance showed a significant effect (p<0.05) with the doses level, with the level of 1 g soft part/kg BW gave the best performance.

Abstract

Endophytic fungi have been recognized as source of broad range biological active metabolites with high chemical structure diversity. The purpose of this research is to isolate and characterize major metabolite produce by the endophytic fungi Penicillium sp isolated from a tea plant. Cultivation of endophytic fungus Penicillium sp (AB2245443) in liquid medium PDB on a rotary shaker at 100 rpm, temperature 25 – 30oC for 7 days, produced a yellow metabolite. Separation of metabolite through chromatography technique and followed by chemical structure elucidation based on MS, IR, NMR spectra and published data showed that the yellow metabolite is (-)-citrinin.

Abstract

The whole nine isolates of endophytic fungi have been obtained from leaves and roots of pandan wangi (Pandanus amarylifolius) collected from Bogor Botanical Garden. Identification of the fungi isolates were conducted based on their morphological characteristics, and revealed that one fungus belongs to the genus of Fusarium, one of Dreschlera, and 7 fungi isolates belong to Coelomycetes. The ethyl acetate extract of the fungi cultures in PDB and GYP media showed a diverse secondary metabolite profiles. Ethyl acetate extract derived from the culture of PWA-2 fungus in GYP medium showed an antifungal activity against Saccharomyces cerevisiae, but not to Fusarium oxysporum and Candida tropicalis. The GC-MS analysis of the active extract showed eugenol as an active component.

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

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).
