Based on phytochemical experiments, avocados also contain phenolics, tannins and flavanoids which have antioxidant activity. Antioxidants are compounds that can be used to counteract free radicals. Dietary fiber and antioxidants are two types of components that are very useful in improving health and being able to prevent various diseases. The extraction method used in this study is reflux where the sample is heated for 6 hours with the solvent used to evaporate at high temperatures, but it will be cooled by the condenser so that the solvent which was in the form of vapor will condense in the condenser and fall again into the reaction vessel so that the solvent will still be there during the reaction. This study aims to analyze the antioxidant activity of the ethyl acetate extract of avocado seeds using the DPPH method. Quantitatively, the ethyl acetate extract of avocado seeds (Persea americana Mill.) was measured at a maximum wavelength of 516 nm using quercetin as a reference standard. The research results showed that the value was 903.08 μ/mL.

Acne is a chronic inflammatory disease of the pilosebaceous glands. One of the bacteria that causes acne is Propionibacterium acne. Preparations that can be made for anti-acne are gel preparations. This study aims to determine whether the ethanol extract of pineapple peel (Ananas comosus L.) can be made into an anti-acne gel preparation and to find out at what concentration the ethanol extract of pineapple peel (Ananas comosus L.) in an anti-acne gel preparation can provide inhibitory activity on the development of Propionibacterium acne bacteria. This research method is true experimental by making anti-acne gel preparations of pineapple peel extract (Ananas Comosus L.) with various concentrations of 2%, 3%, 5% and testing the activity of the preparation against Propionibacterium acne using the agar well method. The results of the gel preparation formula showed that there were significant differences before and after the cycling test in both organoleptic, homogeneity, pH, viscosity, spreadability and adhesion tests. The activity test results obtained were that the largest inhibition zone was the 5% concentration, namely 12.7 mm, which was in the strong category, while the 3% concentration, which was 11.03 mm, and the 2% concentration, which was 8.8 mm, was included in the moderate category.","PeriodicalId":517671,"journal":{"name":"Pharmaceutical Reports","volume":"51 S258","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140394696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
