Abstract

Medicinal plant are part of the flora that grows and is widespread in Indonesia, one of which is mint (Mentha arvensis). Mint plant is an aromatic herbaceous plant that is widely used for air freshener, as a food garnish, and medicine. However, few studies have tested the toxicity of mint leaves. To achieve safe treatment, many studies have been carried out in pharmacological and toxicity testing of medicinal plants. The toxicity test of these medicinal plants uses the Brine Shrimp Lethality Test (BSLT) method after 24 hours of exposure to the sample being tested. This study aimed to determine the toxicity of mint leaves (Mentha arvensis) to shrimp larvae (Artemia salina Leach). Mint leaf extract was obtained from a 24-hour maceration extraction process using 96% ethanol as a solvent. Toxicity test were carried out using the Brine Shrimp Lethality Test (BSLT) method with a concentration of 1 ppm, 2 ppm, 3 ppm, 4 ppm ad 5 ppm. The percentage of deaths of shrimp larvae was calculated and calculation of LC50 value using Probit analysis. The LC50 value was obtained 3,5223 ppm and its categorized as very toxic to shrimp larvae because LC50 < 30 ppm. It can be concluded that mint leaves (Mentha arvensis) can be used as a candidate to be developed as an anti-cancer drug.

Abstract

Medicinal plants are a good source of therapeutic drugs because they contain phytochemical compounds. Cat's whiskers (Orthosiphon stamineus) and miana (Coleus artropurpureus) are plants that are widely used as herbal medicines. However, there are no studies related to toxicology to ensure its safety. The aim of this study was to determine the toxicity of 96% ethanol extract of cat whiskers and miana leaves to shrimp (Artemia salina Leach) larvae. Toxicity test was carried out using the Brine Shrimp Lethality Test (BSLT) method with 48 hours old Artemia salina shrimp larvae. The concentration of the extract used was 1 ppm, 2 ppm, 3 ppm, 4 ppm and 5 ppm. The results of the toxicity test showed that the 96% ethanol extract of cat's whiskers leaves had an LC50 value of 8.0855 ppm, while the 96% ethanol extract of miana leaves had an LC50 value of 4.7067 ppm. Based on the results of the study, it can be concluded that cat's whiskers and miana leaves have the potential to be developed as candidates for anticancer drugs.

Abstract

Wet noodles are a type of noodle with a fairly high water content (35-52%), so it is easy to spoil if stored for more than 12 hours at room temperature. Misuse of the addition of borax and formalin by irresponsible food manufacturers, aims to make wet noodles last longer. This study aims to determine whether the wet noodles sold in several traditional markets in Sidoarjo contain harmful ingredients borax and formaldehyde. The research design in this study began with organoleptic observations on several wet noodles found in several traditional markets in Sidoarjo Regency, followed by a borax test using a borax rapid test kit and a formalin test with UV Vis spectrophotometry and Nash reagent. Based on the test results, it can be concluded that organoleptic observations showed that there were 3 samples of wet noodles with a floury smell and 5 samples with a sour smell, in terms of texture all samples showed a soft and easily broken texture while in terms of color there were 5 samples that were pale yellow and 3 samples were bone white. Based on the results of the qualitative test of borax, all samples of wet noodles were negative for borax and based on the results of the quantitative test of formalin with UV Vis spectrophotometry, showed a negative result of formalin.
