The study was aimed at assessing the levels of some toxic metals of lead and cadmium in selected lipstick products sold in Padang city. Four brands of lipsticks were taken which were BL, NK, PS and WD. The lipsticks were grinded and analyzed for heavy metals (lead and cadmium) using atomic absorption spectrophotometry. Each sample was destructed by nitric acid and perchloric acid (3:1). Destructed samples were added with sodium hydroxide to liberate ammonia and filtered into a 25 mL volumetric flask. The concentrations of heavy metal were measured by using atomic absorption spectrophotometry. The results showed that lead heavy metal contamination was not detected. Whereas, the heavy metal contamination of cadmium in lipstick brands BL, NK, PS and WD were 0.2287, 0.2000, 0.1796 and 0.1220 mg/kg, respectively. The study results showed that all metal contaminations of lead and cadmium were not over the limit which were regulated by National Agency of Drug and Food Control of the Republic of Indonesia.

The nutritional value and biochemical properties of oil are measured by the fatty acids composition in oil and the position of fatty acids (sn-1,2,3) in the triacylglycerol (TAG) molecule. The purpose of this study was to measure the nutritional value based on the fatty acids composition of virgin coconut oil (VCO) and palm kernel oil (PKO), and the position of lauric acid in sn-2. The VCO used was VCO obtained from one of the Pharmacies store in Medan, and PKO from the Oil Processing Plant. The total fatty acid composition was measured by Gas Chromatography. The nutritional value of fat was evaluated by the percentage deviation from 33.33% (ratio: 1: 1: 1) of each group of fatty acid (saturated fatty acids; SFA: monounsaturated fatty acids; MUFA:polyunsaturated fatty acid (PUFA). The distribution of lauric acid in TAG was conducted through hydrolysis by using specific lipase enzymes active at sn-1,3 positions, so that free fatty acids and 2-monoacylglycerol were produced from one TAG molecule. Then free fatty acids were determined by Gas Chromatography. The distribution of lauric acid at sn-2 position was the difference between total lauric acid on TAG before hydrolysis and free lauric acid from sn-1.3 position after hydrolysis. The results showed that PKO nutritional value was better because of the smaller deviation (95.29%) compared with nutritional value of VCO with a greater deviation (118.55%). Lauric acid in sn-2 from VCO and PKO showed that the distribution of lauric acid in sn-2 position was not different,48.33and 48.59%.

Abstract. Taro produces carbohydrate. It has the potential as a substitute material for wheat and rice or as diversification into food and raw materials for pharmaceutical industrial. The aim of this study is to prepare and characterize dextrin in Xanthosoma sagittifolium starch with acid catalyst and enzymatic methods. Xanthosoma sagittifolium was mashed and decanted with distilled water. Dextrin was made by acid catalyst method using HCl 1 N and enzymatic method using α-amylase enzyme. Dextrin was characterized and tested according to the Indonesian National Standard (SNI) 01-2593-1992. The results showed that the yield from acid catalyst and enzymatic methods are 41.73 % and 67.10 %, respectively. The color test showed that dextrin from acid catalyst method is yellowish whereas the enzymatic method gives white dextrin. The qualitative test with lugol solution gives brownish purple dextrin. The characteristic of 80 mesh fineness for dextrin fabricated by acid and enzymatic methods are 94.7 % ± 0.06 and 93.96 % ± 0.02 respectively. Dextrin obtained from acid catalyst has higher water content (8.79 % ± 0.15) than dextrin from enzymatic methods (7.62 % ± 0.23) as well as dextrin from acid catalyst has higher the ash content (0.45 % ± 0.02) than dextrin from enzymatic method (0.42 % ± 0.04). Dextrin made from enzymatic method has higher solubility in cold water (63.09 % + 0.1) than dextrin from acid catalyst method (57.47 % ± 0.25). Dextrose equivalent for dextrin produced is 13.65 ± 0.36 and 15.31 ± 0.46 for acid catalyst and enzymatic methods. Melting points for dextrin obtained from acid catalyst and enzymatic methods are 185 oC ± 0.57 and 182 cC ± 0.57 respectively. Acidity degree of dextrin fabricated from acid catalyst and enzymatic methods are 2.86 ± 0.23 and 4.39 ± 0.4. The research shows that the characterization of dextrin by acid catalyst and enzymatic methods meet the quality requirements for Indonesia National Standard (SNI) 01-2593-1992.

A method was described for the simultaneous determination of dexamethasone in herbal weight gain. Three unregistered herbal weight gains (sample A, B, and C) were analyzed by using HPTLC-densitometry method. Samples were extracted as bases into methanol, separated by HPTLC silica gel 60 F254plate using chloroform: methanol (9:1) as mobile phase followed by densitometry measurement of its spot. The result showed that the detector response was linear for concentrations between 100-500 mg/mL (r =0.998). The limits of detection and quantitation were 9.19 mg/mL and 30.64 mg/mL, respectively. Dexamethasone contents from samples were analyzed. The result showed that two samples (sample A and B) were positively containing dexamethasone and the other one showed a negative result. The average contents of dexamethasone from both samples were 0.23% and 0.25%, respectively.

This study was carried out to investigate the protective effect of ethanol extract of Curcuma mangga rhizomes on paracetamol-induced hepatotoxicity. High dose of paracetamol (1.35g/kg bw) was used to induce hepatic necrosis of mice liver. The male mice received ethanol extract of C. mangga rhizomes (100, 200 and 400 mg/kg BW) for 7 days. The hepatoprotective actvity of extract was compared to normal, positive (curcuma) and negative control. The liver function was evaluated by measuring the biochemistry parameters which include alanine aminotransferase (ALT) and aspartate aminotransferase (AST). In addition, histophatological study on hepatic tissue section was also carried out. The C. mangga extract displayed hepatoprotective effect except at dose of 100 mg/kg bw. The increasing of serum levels of AST and ALT were inhibited after treatment with ethanol extract at doses of 200 and 400 mg/kb bw which was comparable with normal and curcuma as postive control (p>0.05). In addition, histological assessment of hepatic tissue demonstrated no liver damage, specially at dose of 400 mg/kb BW. The result indicate that ethanol extract of C. mangga rhizomes has hepatoprotective effect, especially at doses of 200 and 400 mg/kg bw .
