Abstract

The aim of the study was to determine the inhibitory concentration (IC50) of free radicals on an extract of calabash’s leaves and skins. The sample used in this study was the extract of calabash’s leaves and skins that made of 100 mg/L concentration. Determination inhibitory concentration of free radicals after adding DPPH (2,2-diphenyl-1-picrylhydrazyl) on the samples was determined using UV-Vis spectrophotometry. Concentration variations in leaves and skins extract of calabash used was 5, 10, 15 and 20 mg/L. The positive control used a vitamin C solution with a concentration that identical to the concentration of sample 5, 10, 15 and 20 mg/L. In the other hand, the negative control used a DPPH solution that was dissolved in ethanol p.a. The results showed that the leaves and skins extract of calabash with control of vitamin C have a concentration inhibition of free radicals (IC50) respectively was 9.268 mg/L (leaf extract), 9.332 mg/L (skin extract) and 6.839 mg/L (Vitamin C). The matter it was indicated that leaves and skins extract of calabash was a powerfully natural antioxidant.

Abstract

Mango fruits contain several nutrients which are beneficial for the improvement of people’s nutrition. Vitamin C is one of which highly needed by the body and can be used as a source of antioxidants. Vitamin C level of mangoes is strongly influenced by their varieties, environments, places, fertilizers, maturity levels, and so on. Levels of vitamin C will increase until the fruit is ripe, and will decrease when the maturity level has been exceeded. This research determined the vitamin C level of gadung and golek mangoes based on the maturity levels. gadung and golek mangoes used as the samples were half-ripe, ripe, and overripe fruits. Analysis of vitamin C levels in the samples was done by iodimetry method. The results showed that the vitamin C levels of Gadung were 83.66 mg/100 g on the half-ripe fruits, 101.82 mg/100 g on the ripe fruits, and 92.85 mg/100 g on the overripe fruits. Whereas the vitamin c levels of golek were 57.72 mg/100 g on the half-ripe fruits, 79.30 mg/100 g on the ripe fruits, and 61,14 mg/100 g on the overripe fruits. The data indicate that the ripe fruits of mangoes contain the optimum level of vitamin C.

Abstract

Mercury (Hg) is one type of a dangerous heavy metals. As one of contaminants, mercury enter the aquatic ecosystem through atmospheric decomposition or sourced from the industrial waste externalisation and bilogical and chemical converted in methyl mercury. This research aims to find out and determine the mercury concentrate which contained in sea water, sediment and belanak (Liza melinoptera) network in Palu bay water. The analysis of mercuri content on the tested sample using Automatic Mercury Analyzer. The working principle of the device is gold amalgamation method by heating and separation. The research result showed that the mercury content in belanak network is 0.143 - 0.188 ppm, sediment is 2.453 - 2.800 ppm and the sea water is 0.030 – 0.040 ppm. Based on the decision of the state minister of environmental regarding the guidelines for determination of Hg standard quality for sea water is 0.002 ppm and 0.001 ppm for marine biota. It shows that the Palu bay water condition has been polluted and the belanak is not worth to be consumed.

Abstract

This study aimed to determine the effective concentration of avocado leaves extract in lowering cholesterol blood levels in mice (Mus musculus). The animals test were 15 male mice and were induced with propylthiouracil and high-fat dietary food. Mice were divided randomly into 5 groups with different treatments. Treatments I, II and III were given avocado leaves extracts each with a concentration of 10, 20, and 40%, respectively. Treatment IV was given simvastatin suspension as a positive control, and treatment V was given (Na-CMC) 1% as a negative control. Data were analyzed statistically with analysis of variance (ANOVA) test followed by Duncan test. The results showed that avocado leaves extract contained positively of alkaloids, flavonoids, saponins, tannins, and triterpenoid or steroids. Avocado leaves extract lowered cholesterol blood levels in mice with the most effective concentration was 10% (w/v).

Abstract

The aim of this study is determine the IC50 extracts values of white peel and flesh of red watermelon, white peel and flesh of yellow watermelon as antioxidants. To determine antioxidant activities DPPH reagent was used as well as UV-Vis Spectrophotometry was used to measure vitamin C as a positive control measurement. The samples mixed with ethanol in various concentration of 5, 15, 25 and 35 mg/L. The results showed that the IC50 values for each extract of red watermelon flesh, yellow watermelon flesh, white peel of red watermelon, and white peel of yellow watermelon were 16.619 mg/L, 16.575 mg/L, 14.729 mg/L, and 16.782 mg/L, respectively. Vitamin C as the positive control has IC50 value of 9.526 mg/L. These IC50 values showed that vitamin C had higher antioxidant activity than watermelon extracts, but the extracts of watermelon still categorized in strong natural antioxidants. This study concluded that watermelon is good to be consumed because it is a very strong antioxidant.
