Abstract

Kersen Flower (Muntingia calabura L.) contains several chemical compounds, including flavonoids, tannins, triterpene, saponins and polyphenols that play a role in antioxidant activity. This study aims to determine the antioxidant activity and determine the antioxidant activity value of ethanol extract Muntingia Flower (Muntingia calabura L.) using FRAP (Ferry Reducing Antioxidant Power) method. Extraction was done using maceration method and measurement was done using UV-Vis spectrophotometry method at wavelength of 715 nm. The comparator used was quercetin. The results showed that the concentration of antioxidant activity Muntingia Flower using FRAP method was 684.209 mgQE/g which showed high activity.

Abstract

Chili fruit is a type of medicinal plant which is used as an anti-inflammatory, analgesic, antiflatulant, headache and rheumatism because it contains capsaicin, capsantin, carotenoids, essential alkaloids, resin, volatile oil, multivitamins. This study aims to determine the total flavonoid content of three types of chili using the UV-VIS spectrophotometry method. This type of research is laboratory experimental using a spectrophotometer method based on the determination of extract levels and quarcetin standards. The stages of this study began with sample preparation, extraction of compounds in the sample using ethanol solvent, and ended with the determination of total flavonoid content of the chili fruit sample and quarcetin standard. This study found that the average total flavonoid content for samples of bird's eye chilies, large chilies, and curly chilies was 19.695; 31.72; and 16.011 mg QE/g extract. The percentage of total flavonoid content in bird's eye chilies, large chilies, and curly chilies in this study were 1.9695%; 3.172%; and 1.6011%.

Abstract

Cocoa leaves (Theobroma cacao L.) contain active compounds that have many health benefits. Flavonoids are one of the active compounds contained therein that can prevent the formation of free radicals and reduce tissue damage due to inflammation. This study aims to determine the flavonoid content of ethanol extract of cacao leaves (Theobroma cacao L.) based on the comparison of growing regions using the UV-Vis spectophotometric method. Samples were taken from three regions namely Jeneponto, Wajo and Malino. This research method begins with the preparation of samples by maceration with 96% ethanol solvent, then qualitative analysis is carried out by Thin Layer Chromatography (KLT) method and quantitative analysis is carried out measuring quercetin standards and determining flavonoid levels with a UV-Vis spectrophotometer at a maximum wavelength of 430 nm. The results showed that the ethanol extract of cocoa leaves (Theobroma cacao L.) positively contained flavonoids and had flavonoid levels in the Jeneponto, Wajo, Malino regions of 45.812 mgQE/g extract; 41.556 mgQE/g extract, and; 38.343 mgQE/g extract, respectively. Where the ethanol extract of cocoa leaves (Theobroma cacao L.) from the Jeneponto region has higher flavonoid levels than the other two regions.
