Background: The metabolic disorder caused by high blood glucose levels and pancreatic beta-cell damage is known as diabetes mellitus. Indonesia itself is the 7th country in the world with the number of people with diabetes mellitus. Indonesia occupies rank 7 in the world with the number of people with diabetes mellitus. Apart from that, robusta coffee (Coffea canephora L) is one of the most popular drinks globally, including Indonesia. Chlorogenic acid in coffee beans effectively reduces cell damage due to free radicals, including minimizing excessive glucose release from the liver into the blood. Objective: This study aimed to analyze the effects of chlorogenic acid in the ethanolic fraction of robusta coffee (Coffea canephora L) beans on blood glucose levels in Wistar rats. Method: The researchers applied an experimental study with a randomized pretest-posttest control group design. The beans of robusta coffee were extracted using the Maceration method and then fractionated using a hexane and ethyl acetate solvent. The concentration of the obtained remaining fraction was measured using a spectrophotometer. Furthermore, hyperglycemia testing included 30 Wistar rats induced with 20% glucose for 3 â€“ 4 weeks. They were then given the ethanol fraction of robusta coffee with a dose of 400 mg/kg BW and 500 mg/kg BW. Meanwhile, metformin served as a positive control, and NaCMC served as a negative control. Results: The chlorogenic acid analysis in the ethanol fraction of robusta coffee on a spectrophotometer with a concentration of 37% indicated a decrease of 16.66% on the negative control and 48.06% on the positive control. Meanwhile, the ethanol fraction of each control was 51.53% and 52.16%, respectively. Conclusion: The ethanol fraction of the robusta coffee significantly affects the decrease in blood glucose levels in Wistar rats.

The study was conducted by taking five treatments, namely one negative control group K(-), three treatment groups with variations in concentration (P1) 2.5%, (P2) 5%, P(3) 10% and one positive control group K( +). The results showed that repellent spray had repulsion, control (-) was 50.67%, 2.5% concentration was 68.33%, 5% concentration was 78.67%, 10% concentration was 96% and control (+ ) by 100%. The results of the protection test showed that the repellent spray containing marigold flower essential oil had the highest activity at a concentration of 10%. Based on the results of statistical analysis showed that the calculated f is greater than f table 5% and 1% and the results of the follow-up test of SNK (Newman Keuls) showed that the concentration of 10% was not significantly different from the control (+).

Phenolic content has a role in antioxidant activity. The higher the phenolic content of a test sample, the higher the antioxidant activity, which is indicated by a smaller IC50 value. Methanol and 70% ethanol are solvents that have been proven to be widely used to extract total plant phenolic compounds. This study aims to determine the phytochemical content and the relationship of total phenolic content with antioxidant activity of ethanol and methanol extract of Schleichera oleosa (Lour.) Oken) bark using UV-Vis spectrophotometry. Schleichera oleosa (Lour.) Oken was extracted by maceration using 70% ethanol and methanol as solvent. Qualitative analysis of phytochemical compounds using specific reagents, analysis of total phenolic content, and antioxidant activity test using the DPPH method using UV-Vis spectrophotometry at 764 nm and 515 nm, respectively. The results of the qualitative test showed that the ethanol and the methanol extract was positive for alkaloids, flavonoids, and phenolics. The results of the analysis of total phenolic content and antioxidant activity showed that the 70% ethanol extract had a total phenolic content of 7.6829 mg gallic acid equivalent/g with IC50 28.5240 ppm and the methanol extract had a total phenolic content ofÂ 9.2057 mg gallic acid equivalent/g with IC50 1.6191 ppm. From these results, it was concluded that the higher the total phenolic content, the higher the antioxidant activity.Keywords: Antioxidant; Schlechera oleosa (Lour.)

Beligo (Benincasa hispida (Thunb.) Cogn.), is empirically used by the people of South Sulawesi-Indonesia as an aphrodisiac. Beligo seeds contain alkaloids, phenolics, flavonoids, and unsaturated fatty acids, which have the potential to act as aphrodisiacs. The primary objective of this research is to determine the aphrodisiac activity of an ethanol extract from beligo seeds in mice. The procedure entails extraction and aphrodisiac evaluation using introduction, climbing, and coitus test parameters. Aphrodisiac testing was carried out for seven days using 25 mice as experimental animals, divided into five groups. Each group consists of four males and one female. Group I was given Sod. CMC 1% as a negative control; II, III, and IV were given ethanol extracts of beligo seeds at doses of 350mg/kg, 700mg/kg, 1400mg/kg BW, and group V, as a positive control, was given Yohimbine. The results showed that the ethanol extract of beligo seeds at doses of 350mg/kg BW, 700mg/kg BW, and 1400mg/kg BW had aphrodisiac activity (p=0.0001) compared to Sod. CMC 1% based on data on the amount of introduction and climbing. However, based on data on the number of coitus, it showed that the ethanol extract of beligo seeds at doses of 350mg/kg BW (p=0.072) had no aphrodisiac activity, 700mg/kg BW (p=0.007), 1400mg/kg BW (p=0.0001) had aphrodisiac activity compared to Na-CMC 1% and only a dose of 1400 mg/kg BW had the same aphrodisiac activity compared with Yohimbine (p=0.967). It is concluded that the ethanol extract of beligo seeds had aphrodisiac activity.
