Abstract

Chromolaena odorata or Tekelan has been used traditionally to cope with diabetes mellitus, but the scientific evidence as antidiabetic agent has not been previously reported. Therefore, it is necessary to test the antidiabetic activity using ethanol extract of the tekelan leaves in male mice induced by alloxan. Mice were induced intravenously by alloxan dose of 55 mg/kg bw. After 7 days, mice were diabetic ( KGD > 200 mg/dL ) and were grouped into 6 groups: negative control group (only treated with CMC - Na) , positive control group (glibenclamide 0.45 mg/kg bw) and the 4 other groups were given ethanol extract of Tekelan leaves at doses of 5 , 25 , 125 and 250 mg/kg bw. Dosage administered for 28 days and blood glucose levels was checked every 7 days using a glucotest. Data were analyzed by one-way analysis of variation at 95% confidence level. Ethanol extract of tekelan’s leaves  at doses of 5 , 25 , 125 and 250 mg/kg bw can lower blood levels  from day 7 to day 28 and was significantly different compared to the negative control group ( p < 0.05). Ethanol extract of tekelan’s leaves at doses of 5 , 25 , 125 and 250 mg/kg bw showed antidiabetic activity in alloxan-induced mice.

Abstract

Research on plant leaves Artocarpus camansi (kulu), aims to determine the chemical compounds contained in the hexane extract of the plant leaves. This study begins by isolating the hexane extract, from the leaves of plants A. camansi. Subsequently the extracts were characterized by GC-MS, to determine the fragmentation pattern softhe compunds contained in leaves of A. camansi. Furthermore the hexane extract further fractionated to obtain pure isolates. Pure isolate of the compound as white solid with a melting point of176-1780C. Characterized to the pure compound with1H-NMR, 13C-NMR, DEPT and reinforced with HSQC, and HMBC, expressed asdidekilketon (C21H42O).

Abstract

Research on the applying of SEM-EDX techniques for identification of minerals types of Jades (Giok) Takengon Aceh has been done within this study. Based on data of SEM-EDX, it showed that Jades (Giok) Takengon is belonging to a mineral of silicate. The types of minerals of Jades (Giok) Takengon are Grossular (Ca3Al2(SiO4)3 from the Garnet group, which is a mineral of nesosilicate and the other type  is lizardite, (Mg3Si2O5(OH)4, from the group Serpentine , which is a mineral of phyllosilicate. SEM-EDX can be used as a technique to identify the types of minerals and the results obtained fast and accurate.

Abstract

Antifeedant activity of neem leaf (A. indica A. Juss) has been identified by against Tenebrio molitor bio-indicator. The highest activity was obtained on ethyl acetate extract at 0.5% concentration having Antifeedant Index (AI) of 51.53% and most active at 10% concentration of 82.05%. The method used to test the antifeedant activity is the no choice leaf disk method. Secondary metabolites contained in neem leaf extract (A. indica A. juss) include terpenoids, steroids, flavonoids, saponins and phenolics. Keywords: Neem leaf (Azadirachta Indica A.Juss),  No choice leaf disk method, Antifeedant ActivityREFFERENCES Benge, M.D. 1986.

Abstract

Research compound betasitosterol from the bark of plant of Artocarpus camansi (kulu) and test its antidiabetic has been done. The study begins by extracting samples (3.5 kg),w in the solvent of hexane, hexane extracts obtained,then separated by gravity column chromatography, and was characterized by GC-MS. The results obtained are groups of fractions A, and B. From phytochemical test results, the fraction of group B, has a steroid framework. Group fractions B after rechromatographed is obtained a pure isolates of B. Characterization by 1H-NMR and MS (from GC-MS), pure isolate of B is β-sitosterol. Antidiabetic activity test results showed that the extract of n-hexane, fraction group A and fraction group of B  (containing βsitosterol), can lower blood sugar levels male Swiss Webster mice were performed by the method of glucose tolerance. Dose of extract of n-hexane is  50 mg/dL at minute 30th, 60th and 90th can lower glucose as much as 103 mg/dL; 71 mg/dL; and 49.33 mg/dL. Group of  fraction A of a dose 50 mg/dL at 60th minutes and 90th can lower blood glucose of mice are: 116 mg/dL; and 58 mg/dL. Group B fraction (containing β-sitosterol) at a dose of 50 mg/dL at minute 30th, 60th and 90th can lower glucose by 73 mg/dL; 87 mg/dL; and 73.33 mg/dL. Group fraction of B is the highest in lowering blood glucose average compared with n-hexane extract and group A. Analysis of variance of this fraction were performed by using ANOVA Post hoc analysis procedures one-way of, significant differences (p<0.05) and (p <0.01) conducted using Tukey.
