Abstract

Antihyperuricemia activity tests have conductedon aethanolandn-hexane fraction Africanleaves (Vernonia amygdalina Delile). Hyperuricemia is a condition in which uric acid levels in the blood increases due to the high consumption of purine converted to uric acid by xanthine oxidase. Antihyperuricemia activity test of ethanolic and n-hexane fraction of African leaves (Vernonia amygdalina Delile) conducted on male white mice with variation in doses of 6, 11 and 22 mg/kg BW and variation of measurement time of 1, 2, 3 and 4 hours after administration of the extract orally. Data were analyzed with ANOVA and continued with Duncan test. Ethanolic fraction 11 mg/kg is the most effective fraction lower uric acid levels by 54.62% compared to alupurinol 300 mg/kg BW which lower uric acid levels by 56.91%. Phytochemical screening showed that the ethanolic fraction of African leaves contains triterpenoids, steroids, phenolics, flavonoids and saponins whereas n-hexane fraction containing alkaloids, steroids and flavonoids. These results show the extracts of African leaves have antihiperurisemia activity.

Abstract

Traditional medicine is a supplement that can help maintain a healthy body which is produced from ingredients or ingredients derived from plants, so that it is still in great demand by the public because it is considered safe. Traditional medicinal preparations themselves are not allowed to contain Medicinal Chemicals (BKO). However, along with the increasing public interest, this has led to the circulation of traditional medicines containing BKO in order to obtain products with the fastest/ most effective effects. One of the chemical drugs that are often found are coffeine and paracetamol. This study aims to identify the medicinal chemicals of coffeine and paracetamol in traditional medicine using a solid phase extraction method which is then followed by high performance liquid chromatography with a photo diode array detector. The results obtained were that the coffeine standard produced a retention time of 5.791 with a wavelength of 206 nm and 272 nm while the paracetamol standard produced a retention time of 4.372 with a wavelength of 196 nm and 246 nm. The results of the analysis showed that the samples in the form of traditional medicines did not contain the medicinal chemicals coffeine and paracetamol Keywords: Coffeina, Paracetamol, Medicinal Chemicals, Traditional Medicine

Abstract

Cooking oil is a type of vegetable oil derived from palm plants that has gone through various refining processes. Generally, cooking oil is used repeatedly at high temperatures until the oil is unfit for consumption This results in a decrease in the quality and nutritional value of fried food. In addition, the accumulation of used cooking oil (used cooking oil) can cause environmental pollution. Improving the quality and nutritional value of cooking oil can be done by using the adsorption method. The adsorption method is a method that is carried out by using a number of adsorbents from activated charcoal in the process of refining used cooking oil. Adsorbents from activated charcoal can be made from basic ingredients of agricultural waste such as activated charcoal from coconut shells, corn cobs, snack fruit and others. The adsorbent of activated charcoal can reduce the levels of fatty acids, water content, peroxide levels and acid numbers. The internal adsorption capacity depends on the different adsorbent types, contact time, amount of adsorbent, surface area and structure of the adsorbent and adsorbate concentration. Keywords: Adsorbent, Activated Charcoal, Adsorption Capacity, Used Cooking Oil

Abstract

Coal is a crucial energy source with varying quality levels. It is formed by the accumulation of organic sediments mixed with carbon, resulting from the diagenesis process of plant elements. This study aims to determine the Total Sulfur (TS) and Calorific Value (CV) of coal, which are essential factors in assessing coal quality and economic value. The American Standard Testing and Material (ASTM) method is employed to ensure consistency and standardization in the analysis. From an analysis of six samples, the total sulfur content was determined to be 1.98% for sample A, 1.88% for sample B, 2.06% for sample C, 0.14% for sample D, 0.70% for sample E and 0.18% for sample F. Additionally, the calorific value were determined to be 6267 Cal/g for sample A, 6126 Cal/g for sample B, 6234 Cal/g for sample C, 5189 Cal/g for sample D, 4986 Cal/g for sample E and 3917 Cal/g for sample F. Based on the total sulphur analysis sample D, sample E and sample F can be used in the cement burning process because their total sulphur content is less than 0.8%. Meanwhile, based on the calorific value analysis sample A, sample B and sample C can be used the cement burning process because their calorific value above 6000 Cal/g. Keywords : Coal, total sulphur, calorific value, American Standard Testing and Material.

Abstract

Nutgrass (Cyperus rotundus L.) is one of the Cyperaceae family plants which is this plant belongs to weed. However, it is often used by the Chinese people as a traditional medicine. This review aimed to determine the bioactivity of nutgrass based on their secondary metabolite content. This review was carried out by Literature Review Article method from various journals through Google Scholar and Science Direct. The results of this review indicated that nutgrass has important bioactivities such as antioxidants, antidiabetic, anti-inflammatory, anticancer and antibacterial. Based on the review of those articles, it can be concluded that nutgrass has several important potency for human health to be further studied. Keywords: Cyperus rotundus L, Bioactivity, Secondary Metabolites
