Teak (Tectona grandis L.) is a plant with strong wood and is resistant to pests and diseases. In addition, its leaf extract is widely used by public as an additive in foods both as a preservative and as an alternative food coloring. The objective of this research was to determine phenolic compounds of teak leaves extracted with three different decomposition times (one, two and three weeks of decomposition). Extraction was conducted by using maceration method in which water was used as solvent. Identification of Phenolics was done by using Gas Chromatography. The results showed that the compounds of vanilic acid, salicylic acid, ferulic acid, cumaric acid, gallic acid, benzoic acid and cafeic acid were identified in the analysis. The concentration and composition of phenolic compounds in the extract was determined by decomposition.

The purpose of this research was to induce polyploidy on Impatiens balsamina L. Seedlings of I. balsamina was immersed in 0,01% colchicines solution for 4, 6, 8, and 24 hours. Chromosome of I. balsamina was visualized using squash method stained with aceto-orcein. Morphological observations were conducted on plant height, stem circumference, leaf length and width, number of branches flowering time and size of flower. The result revealed that 0,01% solution of colchicine was able to induce polyploidy on I. balsamina. Obsevation on morphological characteristic showed that colchicine treatment increased plant height, stem circumference, leaf length and number of branches. Colchicine treatment induced earlier flowering time, but flower size was unaffected. Twelve chromosomes (2n = 2x = 12) were observed in the diploid seedlings while 25 chromosomes were observed in the tetraploid (2n = 4x = 24 seedlings.

Tanaman kamboja mengandung senyawa alelopati yang menghambat pertumbuhan tanaman di sekitarnya. Penelitian ini bertujuan untuk mengetahui kandungan fitokimia ekstrak daun kamboja dan pengaruhnya terhadap pertumbuhan tanaman jahe emprit (Zingiber officinale var. amarum). Penelitian dilaksanakan dalam dua tahap yaitu, tahap pertama uji fitokimia ekstrak daun kamboja merah dan daun kamboja putih, serta tahap kedua berupa uji respon pertumbuhan tanaman jahe emprit yang diberi perlakuan ekstrak daun kamboja. Variabel respon pertumbuhan yang diamati adalah jumlah tunas tumbuh, tinggi tanaman, jumlah daun, jumlah akar, berat rimpang, berat basah berangkasan, dan berat kering berangkasan. Hasil uji fitokimia menunjukkan bahwa pada ekstrak daun kamboja putih dan kamboja merah memiliki jenis golongan senyawa aktif yang sama yaitu triterpenoid, steroid, flavonoid, dan polifenol dalam intensitas yang berbeda. Ekstrak daun kamboja putih memberikan efekdaya hambat yang lebih kuat dibandingkan dengan ekstrak daun kamboja merah. Persentase daya hambat ekstrak daun kamboja putih terhadap tinggi tanaman jahe emprit sebesar 80,5%, berat basah berangkasan 64%, jumlah daun 54%, berat kering berangkasan 54%, jumlah tunas tumbuh 33,3%, dan berat rimpang 31,9%.

Penelitan ini bertujuan untuk mengetahui pengaruh ekstrak rebung bambu tabah terhadap perilaku kawin mencit jantan. Rancangan yang digunakan pada penelitian ini adalah rancangan eksperimental sederhana dengan4 kelompok perlakuan dan 6 ulangan, yaitu P0: Kontrol (Perlakuan dengan pemberian CMC Na 0,5 %), P1: (Perlakuan dengan pemberian ekstrak 200 mg/kg bb), P2: (Perlakuan dengan pemberian ekstrak 300 mg/kg bb) dan P3: (Perlakuan dengan pemberian ekstrak 400 mg/kg). Perlakuan ekstrak rebung bambu tabah diberikan pada mencit jantan secara oral setiap hari selama 33 hari dan pengamatan perilaku kawin dilakukan 3 hari sekali. Variabel yang diamati untuk menilai perilaku kawin mencit jantan adalah jumlah mount. Data dianalisa dengan menggunakan uji One Way Annova. Hasil penelitian menunjukkan bahwa pemberian ekstrak rebung bambu tabah berpengaruh signifikan terhadap peningkatan perilaku kawin mencit jantan (P<0,05).

There were 65 species of trees have been identified in Baturning village, District of Abiansemal, Regency of Badung, Bali, which were spread out around the river bank, cemetery (around Dalem temple), around the settlement, non-irrigated farm (plantation or “tegalan”) and rice field. Thirty eight (38) % out of them were observed to be available around the settlement. Most of trees in Baturning (61 species or 94%) have been used by the local community. The rest were uncultivated. From the use, trees in Baturning most were used for human consumption (24%). On the village has not been found protected species, even though in the village were found 22 species of trees which considered to be rare in Bali, namely: Bayur, Bentenung, Beringin, Cempaka, Ee, Jaka, Jeruk Bali, Juwet, Kelor, Kendal, Klampuak, Lempeni, Lenggung, Mahoni, Mengkudu, Palem Raja, Poh-Pohan, Pule, Sandat, Sentul, Udu, and Wani.

A research on effectiveness of extracts of teak (Tectona grandis L. f) leaves in inhibit thegrowth of a species of fungi, Hormiscium sp. has been carried out. The leaves used in thisresearch were young leaves (number 1 and 2), and old ones (number 5 and 6), with fourconcentrations: 0, 2, 5, and 10 %. The media utilised were bean sprouts agar, and thereplications was 3 times. Qualitative tests were undertaken for the flavonoids, while alkaloidtests were based on Culvenor Fitzgerald methods. Qualitative tests of triterpenoids andsteroids were undertaken by utilising Lieberman – Burchard reagents (L-B reagents).Parameters observed were colony diameters, micellium weights (dry mass), and numbers ofconidia (ml). Results of this research showed that extracts of teak (T. grandis) leaves wereable to inhibit the growth of Hormiscium sp. The capability of inhibitions was increased asthe extract concentrations increased (for both, that of the young and old leaves), eventhough extracts of the young provided a higher capability of inhibitions compared to theold ones.

ABSTRACT Rhapidhophora pinnata, Schott is a traditional medical plant that has been use remedy for treatment of hypertension, stroke. Aims of this research is to determine the effect of Rhapidhophora pinnata Schott leaf extract toward mouse (Mus musculus L) liverhistological structure. This research used completely randomized design with 28 female mice that were divide into 4 groups of P0 (control) received 0,9% NaCl, group P1, P2, and P3 received 50, 100 and 150 mg/kg bw respectively by oral administration. The treatment were given daily for 14 days. All of the mice were sacrificed by ether after 15 days. The liver were examined for their histopathological changes, namely fatty degeneration, hydropic degenaration and necrosis. Results were statistically analised by Kruskal-Wallis method. Treatment groups showed no significant differences with regard of liver histopatological changes, however hemorrhage, sinusoid congestion and inflamatory cell infiltration were found in liver.

Senyawa antioksidan, flavonoid, dan saponin banyak terkandung dalam daun belimbing besi (Averrhoa carambola) sehingga tujuan dari penelitian ini untuk melihat pengaruh antidiabetes ekstrak daun belimbing besi pada mencit. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 6 perlakuan, yaitu P1 (aquadest tanpa aloksan) sebagai kontrol negatif, P2 (aquadest dengan aloksan) sebagai control positif, P3 metformin 500 mg/kgBB), P4 (aloksan + ekstrak daun belimbing besi 100 mg/kgBB) , P5 (aloksan + ekstrak daun belimbing besi 150 mg/kgBB), P6 (aloksan + ekstrak daun belimbing besi 200 mg/kgBB). Sebelumnya hewan coba dijadikan diabetes dengan menginduksi aloksan sebanyak 120 mg/kgBB secara intramuscular pada otot paha. Pembuatan ekstrak daun belimbing besi menggunakan metode maserasi. Setelah hewan diabetes, diberikan perlakuan ekstrak etanol daun belimbing besi sesuai rancangan percobaan, dimulai hari ke-7 sampai hari ke-21. Kadar glukosa darah diukur dengan glucometer setiap minggu. Hasil penelitian menunjukkan nilai penurunan kadar glukosa darah terbaik terjadi pada minggu pertama dan minggu kedua. Pada minggu pertama, perlakuan metformin mampu menurunkan glukosa darah mencit sebanyak 88.4%, sedangkan perlakuan ekstrak etanol daun belimbing besi dosis 200 mg sebanyak 60%. Pada minggu kedua, 65.8% untuk metformin, dan 63% untuk dosis ekstrak daun belimbing 200 mg/kg BB. Ekstrak etanol daun belimbing besi berpotensi sebagai obat antidiabetes. Kata Kunci: mencit, diabetes mellitus, glukosa darah, daun belimbing besi.
