Abstract

The leaves and seeds of pangi (Pangium edule Reinw.) contain alkaloids, flavonoids, saponins, and tannins, which acts as antioxidants. Antioxidants are needed to protect the body and inhibit the negative impact of free radicals due to the oxidation reactions that occur. Antioxidants are compounds that inhibit oxidation reactions by binding free radicals and molecules. This research aims to determine the comparison of the antioxidants activity of pangi (Pangium edule Reinw.) leaves and seeds using the DPPH (1,1,-Diphenyl-2-Picrylhydrazyl) method. Reactive research method, experimentally, namely by carrying out serial dilutions of concentrations of 10, 20, 30, 40 and 50 ppm in each test solution, then adding the DPPH solution and measuring the antioxidants activity with a UV-Vis Spectrophotometer. After that, the IC50 (Inhibitor Concentration 50) value and the AAI (Antioxidant Activity Index) value are calculated, and the data were analyzed using ANOVA. The results of calculating the IC50 and AAI values are that the IC50 value of the pangi leaf ethanol extract is 49.6061 ppm (AAI=1.007), while the IC50 value of ethanol extract of pangi seeds is 50.2027 (AAI=0.9959). From the results of research and data analysis, it can be concluded that the ethanol extract of pangi leaves has higher antioxidant activity compared to the ethanol extract of pangi seeds.

Abstract

Infectious diseases are still a major health problem in several countries, especially in developing countries. The medication used to treat bacterial infections is obtained by utilizing herbal plants obtained from natural ingredients. Pumpkin fruit extract (Cucurbita moschata) contains flavonoids. tannins, saponins, and alkaloids Pumpkin fruit is effective as an antidiabetic, an antihypertensive, an antitumor, an antibacterial, and an antioxidant. This study aims to determine the antibacterial activity of the methanol and n-hexane fractions of yellow pumpkin (Cucurbita moschata) fruit extract and at what concentration the methanol and n-hexane fractions of yellow pumpkin (Cucurbita moschata) fruit extract can have antibacterial activity against Escherichia coli and Staphylococcus aureus. This research uses laboratory-experimental research methods. Antibacterial testing in this research involved sterilization, making test solutions, and testing. The results of the antibacterial test on the inhibition zone of the methanol fraction of pumpkin fruit against Escherichia coli and Staphylococcus aureus bacteria at concentrations of 20%, 30%, and 40% were in the strong category, while the n-hexane fraction had an inhibition zone in the weak category for Escherichia coli and Staphylococcus aureus bacteria. Conclusion: The methanol and n-hexane fractions have antibacterial activity against Escherichia coli and Staphylococcus aureus, and the concentrations with antibacterial activity are 20%, 30%, and 40%.
