PHYSIOLOGICAL STATUS, BLOOD PROFILE AND BODY COMPOSITION OF SHEEP FED WITH CA-SAPONIFIED LEMURU OIL COATED BY HERBS

<p>This study was aimed to evaluate the physiological status, blood profiles and body composition of sheep fed with Ca-saponified lemuru oil coated by herbs. Twenty fat-tailed sheep (av. BW 23±1.2 kg) were used in this experiment by using Completely Randomized Design with five treatments ration and four replications of each. Sheep fed with concentrate containing 3% Ca-saponified lemuru oil and king grass (1:1) ad libitum. Treatments were control diet without herbs (R1); Ca-saponified lemuru oil coated by curcumae domestica (R2); coated by Zingiber officinale Rosc (R3); coated by Eugenia polyantha (R4) and coated by Pluchea indica Less (R5). Data of physiological parameters were measured three times a day, in the morning, at noon and afternoon. Blood samples were collected at the end of the experiment through jugular vein, together with zero sample for Urea Space measurement. The variables observed were physiological data (heart rate, respiration rate, and rectal temperature), blood profiles (erythrocyte, hemoglobin, packed cell volume (PCV), leucocytes) and body composition (water, protein and fat) measured using Urea Space technique. Results of the study showed that sheep fed with Ca-saponified lemuru oil coated by herbs was not significantly different on heart rate, respiration rate and rectal temperature among treatments. Meanwhile, total leucocytes, neutrophil cell, and lymphocytes significantly increased (P<0.05) by the treatment. Body composition percentage (water, protein and fat) were same in all treatments, except the total body fat and energy retained. In conclusion, supplementation of 3% Ca-saponified lemuru oil coated by Curcumae domestica, Zingiber officinale Rosc, Eugenia polyantha and Pluchea indica Less in fat-tailed sheep had no effect on physiological parameters, but improved the leucocyte and neutrophil cells.

Identification of hydroxychavicol and its dimers, the lipase inhibitors contained in the Indonesian spice, Eugenia polyantha

Inhibition of pancreatic lipase is effective for a prevention of obesity. Eugenia polyantha is a tropical tree whose leaves are known as a spice and also as an ingredient for Jamu, the traditional medicine of Indonesia. We found inhibitory activity against pancreatic lipase in the extract of E. polyantha leaves. Purification of the active principals resulted in isolation of hydroxychavicol, and two structurally new dimers. All of the isolated compounds showed inhibitory activity against the porcine pancreatic lipase and high content of hydroxychavicol (1.83wt.%) indicated this compound to be responsible for the majority of inhibitory activity of E. polyantha extract. Furthermore, hydroxychavicol is reported to possess anti-carcinogenic, anti-oxidant, anti-microbial and anti-inflammatory activity which is related to traditional usage of this plant. These results offer this plant as an attractive material for treating various health problems including obesity.

In vitro Antioxidative Activities and Polyphenol Content of Eugenia polyantha Wight Grown in Indonesia

Antioxidative activities of three bark extracts (methanol, methanol-water and water) from Eugenia polyantha Wight grown in Indonesia were evaluated using various in vitro assays; 2, 2-diphenyl-1-picrylhydrazyl radical-scavenging, hydrogen peroxide-scavenging and beta-carotene bleaching assays. From the assays, Eugenia polyantha bark extracts were found to be potential antioxidative activities. The methanol-water extract showed the highest level of free radical-scavenging activity (Effective dose (ED50) = 0.18 mg mL-1) and protection from beta-carotene bleaching (85.7% at 100 microg mL-1). The methanol-water extracts showed the highest total phenolic content (856 mg gallic acid equivalent (GAE)/g and 161 mg catechin equivalent (CE)/g) and total antioxidative capacity (449 mg ascorbic acid equivalent (AAE)/g). Furthermore, it exhibited dose-dependent antioxidative activities. A relationship between total antioxidative capacity and total phenolic content was recognized in the three extracts from Eugenia polyantha bark.

The influence of salam leaf (Eugenia polyantha) adding on the microbiological quality, organoleptic quality and salted duck egg shell-life during storage in room temperature

Fitri A, Setyaningsih R, Susilowati A. 2007. The influence of salam leaf (Eugenia polyantha) adding on the microbiological quality, organoleptic quality and salted duck egg shell-life during storage in room temperature. Biofarmasi 5: 47-54. The aim of this research was to determine the influence of salam leaf (Eigenia polyantha Wight) concentration variation on the microbiological quality, organoleptic quality and the salted duck egg shell-life during storage in room temperature. In this research, the salam leaf concentration that added consisted of four levels. The ratio of salam leaf-water were 1:4, 2:4, 3:4, and control. The analysis of experimental parameters was carried out once in 2 weeks for 4 weeks. The experimental parameters were the presence of Salmonella sp., Staphylococcus aureus number, organoleptic value, and total volatile bases (TVB). The presence of Salmonella sp. and the number of Staphylococcus aureus data were analyzed descriptively, while the organoleptic data were analyzed by using nonparametric test and followed with correlation and regression analysis. Data were analyzed by using a General Linear Model on TVB and followed with Duncan Multiple Range Test (DMRT) on the significance level of 5%, correlation and regression analysis. The result of this research showed that there was no Salmonella sp. contained in the salted egg for 4 weeks storage. The highest number of Staphylococcus aureus was found on the salted egg which stored for 4 weeks and ratio 1:4 of salam leaf-water. However, the result of organoleptic test showed that salam leaf addition did not influence on the accepting of salted duck egg significantly and had a negative correlation. Salam leaf concentration influenced on TVB of the salted duck egg in different storage duration at a room temperature and had a positive correlation.
