Twenty-five rats were divided into five groups. Negative control group was administered with distilled water. The positive control group was administered with orlistat dose 14.2 mg/kgBW. Group 3rd, 4th, and 5th were treated with white tea infussion doses of 125, 250 and 500 mg/kgBW/day, respectivelly. period and feed intake was calculated daily during the treatment. White tea doses of 500 mg/kgBW decrease the total cholesterol by 37.16±11 mg/dL, lipase level of 23.70±0.64 U/L, weight up to 3.53±1.21 g/day and decrease feed intake by 12.71±1.76 g/day. The infusion of white tea can decrease total cholesterol level, lipase level, body weight and feed intake. This study concluded that infusion of white tea has antiobesity and antihypercholesterolemic effect on rats fed high-fat-diet.

      Abstract:  The Eurycoma longifoliais bitter therefore, to address this problem, it is prepared in a capsule form. The capsule dosage form  must has  the parameters of good quality, thus expected to increase the potential use of biodiversity and the interest of the community in consuming the medicine from the natural materials. The purpose of this research is to get the capsule product of ethanol extract of the Eurycoma longifolia root of quality through the test of total plate value and yeast yeast contamination, the determination of the metal content of Pb, Hg, Cd and the level of flavonoids released in the capsule dissolution test of ethanol extract Eurycoma longifolia root. The result of this research shows that the dissolution efficiency (DE120) capability of ethanol extract of Eurycoma longifolia root is 81,04±2,38%. Test of heavy metal content in capsule of  of ethanol extract of Eurycoma longifolia root found level of Pb equal to 4,132 ppm and not detected content of Cd and Hg in capsule. This indicates that the capsule meets the requirements set by BPOM RI. Tests for total plate numbers (ALT) and yeast capsule ethanol extract of the E. longifolia root were each obtained data of 70 x 102 colonies / g and 4 x 102 colonies / g. It also shows that the capsules meet the requirements by BPOM RI.

  • Comparison of antioxidant activities from four species of piper

    • Authors: Muhamad Insanu, Lia Marliani, Nabila Pandu Dinilah
      Pages: 305 - 312
      Abstract: Some species from Piper genus were known for traditional medicine and ornamental plant. Previous studies showed that Piper betle and Piper acre had antioxidant activities. But, the study of antioxidant activity from other species of Piper was still limited. Because of that, the purposes of this study were to determine the antioxidant activity, and total flavonoid content of Piper nigrum, Piper aduncum, Piper retrofractum, and Piper crocatum. Extraction was done by gradient maceration using n-hexane, ethyl acetate, and ethanol as solvents. The extracts were concentrated by rotary evaporator. Antioxidant activity was evaluated by DPPH (1,1-diphenyl-2-picrylhydrazyl) free scavenging method. Total flavonoid determination was done by colorimetry method using aluminum chloride (AlCl3) as a reagent. The result showed that the IC50 values of Piper nigrum, Piper aduncum, Piper retrofractum, and Piper crocatum were ranged between 58-1249 μg/mL. The total flavonoid values of all extracts were between 1.4-8.3 mg QE/100 mg. The extract which had the strongest antioxidant activity was the ethanol extract of Piper nigrum with an IC50 value was  57.72 μg/mL. The highest values of total flavonoid was showed by the ethanol extract of Piper aduncum which was 8.3 mg QE/100 mg extract.
