Banana peel is a very large amount of waste material (banana fruit waste). In general, banana peels have not been used optimally. Based on the research results, kepok banana peel contains secondary metabolites in the form of flavonoids, alkaloids, tannins and saponins. This study aims to determine the total phenolic content and total flavonoid content of the ethanol extract of kepok banana skin (Musa pradisiaca L). Extraction was carried out by maceration method with 96% ethanol solvent. Determination of total phenol content used the Folin-Ciocalteu method with gallic acid as comparator compound and the determination of total flavonoid content used the colorimetric method with 10% AlCl3 and 5% acetic acid as reagents. The results showed that kepok banana peel extract had an average total phenolic content of 13.4495 mg GAE/g ± 1.5473206 and an average total flavonoid content of 8.5468 mg QE/g ± 0.947422695.

The leaves of the ferns Asplenium nidus L., Asplenium adiantum nigrum L., and Aspidium biserratum Sw. contains secondary metabolites of flavonoids, alkaloids, saponins, tannins, and phenols. Phenolic compounds are the largest secondary metabolites in plants. The benefits of phenolic compounds are as antioxidants and their ability to prevent various diseases such as cancer, anti-inflammatory, anti-microbial and anti-diabetic. The purpose of this study was to compare the total phenolic content of the ethanol extracts of the leaves of the ferns Asplenium nidus L., Asplenium adiantum nigrum L., and Aspidium biserratum Sw. by UV-Vis spectrophotometry method. The research conducted was non-experimental research. The objects studied were the total phenolic content of the ethanol extract of the leaves of the ferns Asplenium nidus L., Asplenium adiantum nigrum L., and Aspidium biserratum Sw. The research phase included plant determination, sample collection, simplicia processing, extract preparation, water content determination, extract phytochemical screening, and phenol content determination using the UV-Vis spectrophotometry method using Folin Ciaocalteau reagent. Total phenol content is expressed in units of mg GAE (gallic acid equivalent)/g extract. The data analysis used in this study used statistics using the one way ANOVA program in the form of the results of testing the total phenolic ethanol extract of the ferns Asplenium nidus L., Asplenium adiantum-ningrum L., and Aspidium biserratum Sw.
