ANTIDIABETIC ACTIVITY TEST OF ETHANOL EXTRACT BROCOLI (BRASSICA OLERACEA VAR. ITALICA) IN WHITE MALE RATS

Diabetes is a chronic disease characterized by excessive blood glucose levels caused by absolute and relative insulin deficiency. The stages in this study were sampling, identification of samples/plants, simplification, simplification screening, and preparation of extracts by maceration. The method used in the diabetes activity test uses a glucometer to induce alloxan in rats at a dose of 150 mg/kg body weight. The test animals were 25 rats which were divided into 5 treatment groups namely CMC Na 0.5% (negative control), glibenclamide (positive control) 0.45 mg/kg body weight and EEB dose 200 mg/kg body weight, 400 mg/kg body weight and 600. mg/kg body weight. kg B.W. kg body weight as a test material given orally. Measurement of blood glucose values ??according to Allox and on days 3, 5, and 7 after administration of the test substance, namely EEB. The test results data were analyzed statistically using one-way ANOVA at a 95% confidence level followed by Tukey's post hoc test. The results of the phytochemical screening showed that EEB contains alkaloids, flavonoids, tannins, saponins, and glycosides. The results of the diabetes efficacy test showed that EEB doses of 200, 400, and 600 mg/kg BW had an anti-diabetic effect on male white rats. The EEB dose of 600 mg/kg is the most effective. Post hoc Tukey test results showed that EEB doses of 200 mg/kg, 400 mg/kg, and 600 mg/kg were not significantly different from the positive control glibenclamide 0.45 mg/kg (p>0.05) and 200,400 ug. and 600 mg/kg BW were significantly different from the negative control CMC Na 0.5% (p<0.05)

Socialization of Rhodamine B Dye Content in Liptint Sold in Lubuk Pakam Which is Analyzed Using UV-Vis Spectrophotometry

Rhodamine B is a synthetic dye that is always used to color paper, textiles or ink. The use of rhodamine B is very unsafe for physical fitness and health. When applied without an agent in the body, Rhodamine B irritates the respiratory tract and can cause cancer and liver damage. Even though it has negative effects, this dye is still widely used by irresponsible individuals to make a profit, especially in food processing and cosmetics. Objective: This community service is carried out with the aim of educating the public about the dangers of rhodamine for our bodies, as well as finding out the Rhodamine B content in lipsticks distributed in Lubuk Pakam, where lipstick is one of the cosmetics most widely used by the public, especially women. Method: The method used is socialization by providing direct outreach to the community, especially to mothers and teenagers about the dyes in lip tint which refer to the research results. Qualitative analysis of rhodamine B was carried out using TLC with the mobile phases of ethyl acetate, methanol and ammonia (45 :25:30), while quantitative analysis was carried out in the determination using UV-VIS spectrophotometry at 545 nm. The strategy used in providing knowledge about the dangers of dyes in cosmetics is by giving direct lectures about the various kinds of dyes used in cosmetics, the potential dangers that will arise if cosmetics with excessive dyes are used along with the characteristics of cosmetics with dyes and It is hoped that the public can avoid cosmetics that are indicated to use dyes and get safe cosmetic solutions using natural dyes
