Abstract

Indonesia is one of the countries with a diversity of plants, one of which is the potato plant (Solanum tuberosum L.). Some compounds found in potato peels have pharmacological activities, one of which is antioxidants. This study aimed to determine the total phenol content and the antioxidant activity produced by potato peel ethanol extract. The methods for total phenolic content used the Folin-Ciocalteu method and the DPPH(2,2-diphenyl-1-picrylhydrazyl) method for antioxidant activity. The result obtained from this study was that the total phenol content in ethaol extract of potato peel was 152.9 mg GAE / g extract and antioxidant activity showed with IC50 value was 30,339 ppm, which means that potato peel ethanol extract has a very strong antioxidant activity.

Abstract

The mangrove plant (Hibiscus tiliaceus L.) is widely cultivated in tropical regions such as Indonesia because almost all parts of plant are believed to provide many benefits. Som of the benefits of the mangrove plant include laxative, treating earache, antibacterial, and antioxidant. The aim of the research is to analyze the content of phytochemical compounds contained in the mangrove plant and its antioxidant activity. This research uses a journal review method based on data collection carried out by inclusion and exclusion obtained from the google scholar, science direct, taylor and francis, garuda, and sage publication data search engine, including textbooks and scientific articles published above year of 2013. The result of the research is the phytochemical compounds found in mangrove plant are anthocyanin compounds, amides, coumarins, phenols, organic acids and flavonoid compounds that identified in the leaves, stems, and bark in mangrove plants uses several of solvents, there are methanol water, chloroform, and ethanol. The part of the plant that has antioxidant activity is the leaves which has strong antioxidant activity (IC50 = 86,5 µg/mL).
