Temulawak (Curcuma  xanthorrhizaRoxb.) belongs to the family Zingiberaceae, has been empirically used as herbal medicines. The research was aimed to evaluate three promising lines of Temulawak based on their high bioactive contents (xanthorrhizol and curcuminoid) and its in vitro bioactivity (antioxidant and toxicity), and to obtain information on agrobiophysic environmental condition which produced high bioactive compounds. The xanthorrhizol and curcuminoid contents were measured by HPLC. In vitro antioxidant and toxicity were determined by DPPH (1,1-diphenyl-2-picryl-hydrazyl) method and BSLT (Brine Shrimp Lethality Test). The result showed that promising line A produced the highest yield of bioactive and bioactivity, i.e. 0.157 and 0.056 g plant-1of xanthorrizol and curcuminoid respectively. The IC50 of antioxidant activity was 65.09 mg L-1and LC50of toxicity was 69.05 mg L-1. In this study, Cipenjo had the best temulawak performance than two other locations. According to the agrobiophysic parameters, Cipenjo environmental condition was suitable for temulawak cultivation with temperature 28-34 ºC, rainfall ± 223.97 mm year-1 and sandy clay soil. Keywords: antioxidant, curcuminoid, promising lines, temulawak, xanthorrhizol

Curcuminoids of Curcuma manggo believed to have antioxidant properties that can prevent the occurrence of atherosclerosis.  However, the mechanism at the molecular level is not clearly known. Increase in intracellular adhesion molecule-1 (ICAM-1) will result in endothelial cell dysfunction that initiates athersclerosis. The expression of ICAM-1 can be triggered by oxidized LDL molecules. The purpose of this study is to elucidate the effects of curcuminoids temumangga (Curcuma mango) on the expression of ICAM-1 induction in endothelial cell culture. Prior to the induction of the expression of ICAM-1, endothelial cell culture was pre-incubated with curcuminoids extract for 48 hours with concentration of 2 ppm and 8 ppm, then further incubated with oxidized LDL for 24 hours. The treated cells were compared to 5 µM Cu2+ induced endothelial cell culture with or without LDL  from Macaca fascicularis.  ICAM-1 expression was determined by immunohistochemistry using anti-ICAM-1 antibodies and visualized with staining by 3.3-diaminobenzidin tetrahidrochloride (DAB). Results showed that surface-induced endothelial cell culture with ion Cu2+ stained well by DAB as brown yellow, which indicates ICAM-1 expression. Curcuminoids extract of  8 ppm reduced induction of ICAM-1 response. Induction of ICAM-1 expression by oxidized LDL caused foam cell accumulation in addition to ICAM-1 expression.Key words: Curcuminoid, low density lipoprotein (LDL), Macaca fascicularis, intracellular adhesion molecule-1 (ICAM-1), immunohistochemistry

Komposisi kimia yang terkandung dalam ekstrak obat bahan alam merupakan suatu komposisi yang kompleks, dengan demikian pengujian keotentikannya tidak dapat dilakukan melalui pedekatan tunggal.  Salah satu teknik analisis yang dapat menggambarkan secara menyeluruh karakteristik kimia suatu bahan adalah teknik spektroskopi FTIR. Spektra FTIR dihasilkan dari interaksi antara energi sinar inframerah dan komponen kimia penyusun campuran bahan, sehingga suatu spektra FTIR merupakan indentitas khas campuran tersebut. Keotentikan komposisi suatu obat bahan alam pada studi  ini ditentukan berdasarkan pada analisis komponen utama spektra inframerahnya.  Studi dilakukan pada obat bahan alam/fitofarmaka penurun tekanan darah (Tensigard® : terdiri dari ekstrak seledri dan ekstrak daun kumis kucing). Pengukuran spektra inframerah dilakukan terhadap formula obat yang persentase komposisinya ditentukan melalui simplex lattice design. Selain itu pengukuran spektra inframerah juga dilakukan terhadap formula obat dengan mengganti (adulterasi) ekstrak kumis kucing dengan obat sintetis (reserpin) dan ekstrak sambiloto. Berdasarkan plot antara skor komponen utama pertama dan skor komponen utama kedua menunjukkan plot tersebut dapat digunakan untuk mendeteksi komposisi obat, tetapi tidak dapat mendeteksi adanya adulterasi komposisi oleh bahan lain.   Kata Kunci : model otentikasi fitofarmaka, simplex lattice design, komponen utama, tensigard

Darusman3), dan Rimbawan1) 1) Departemen Gizi Masyarakat, FEMA IPB 2) Departemen Ilmu dan Teknologi Pangan, Fateta IPB 3) Departemen Kimia, F-MIPA IPB   Diterima  25 November 2009 / Disetujui 26 April  2010 ABSTRACT   Margarine is a water in oil (w/o) emulsion product which is widely used for household cooking and baking industry. Consuming of margarine, which contains trans fatty acid may cause health problem due to the increase of LDL cholesterol. Since margarine is also a good carrier of phytosterol which prevent the absorption of cholesterol, there is a possibility to formulate a healthier margarine. In this research formulation and characteristics of products was investigated. The research work consisted of two steps: (1) supplementation of wheat germ sterol into margarine (two methods) and  (2) analysis of physical, chemical characteristics and hedonic score. Parameters of physical characteristics were melting point and emulsion stability, whereas chemical characteristics were water and oil contents. The hedonic test was carried out based on product’s color, odor, taste, texture, and spreadability. Results showed that method II of supplementation produced better margarine than method I, in which the concentration of sterol in the margarine was higher with a melting point similar to that of control, better emulsion stability, and higher hedonic score. Supplementation process was carried out by mixing sterol into fat phase melted at 50 0C, followed by mixing with aqueous phase at 4 0C. Sterol used for method II was extracted using mixed solvent of hexane and ethanol at the ratio of 1:2 (v/v), which was resulted from previous experimentation.   Key words: supplementation, wheat germ sterol, margarine

Mangosteen has a good prospectus for international market. Many people in the world like this fruit because it is delicious, has high nutrient contents, and it can be consumed as a fresh fruit. The growth of mangosteen is very slow with a very long juvenile period because of its long dormancy period. The objective of this research was to study the dormancy periods and growth rhytm of shoot and root of young and adult mangosteen seedlings. The research used completely randomized design and consisted of two experiments. The first experiment was to study the dormancy and flushing periods. The second experiment was to study the growth patterns of shoot and root foom several ages of mangosteen seedlings. This research was conducted at Mekarsari Fruit Park, Cileungsi, Bogor. The result of the experiment showed that two years old of mangosteen seedling had 5 flushes per year, four years old of mangosteen had 3-4 flushes per year, and eight years old of mangosteen only had 2 flushes. Dormancy periods were significantly different between 2,4 and 8 year of mangosteen seedling. After the seedlings have branches, the dormancy periods become twice as many as that before branching. The roots grew rapidly two weeks before flush and slower after flush occurred.   Key words: Garcinia mangostana, dormancy, flush, seedling
