dc.descriptionThis study aims to determine the compoition of secondary metabolites and the degree of antioxidant activity of durian peel extract (Durio zibethinus murr). the study was conducted with the stages of sample prevention, sample extraction, phytochemical screening, and antioxidant activity tests, using qualititative and quantitative methods. The extract was tested with DPPH (Difenil fikril hidrazil). As a free radical by measuring the absorcbance of DPPH using a spectrophotometer. The results of this research showed that durian peel extract containing chemical compounds such as alkaloids, terpenoids, saponins which have antioxidant activity. Antioxidant activity test durian skin extract obtained IC50 value of 57,5487 did not meet the standard. Vitamin C antioxidant activity test results obtained IC50 value of 15,9617 meet the standard.en_US
dc.description.abstractPenelitian ini bertujuan untuk menentukan komposisi senyawa metabolit sekunder dan derajat aktivitas antioksidan dari ekstrak kulit durian (Durio zibethinus murr). Penelitian dilakukan dengan tahapan Prevarasi sampel, ekstraksi sampel, skrining fitokimia, dan uji aktivitas antioksidan. Metode penelitian yaitu metode kualitatif dan kuantitaf. Ekstrak di uji dengan DPPH (Dipenil pikrilhidraz u7il) sebagai radikal bebas dengan mengukur absorbansi DPPH menggunakan Spektrofotometer. Hasil pengujian ini menunjukan ekstrak kulit durian mengandung senyawa kimia golongan alkaloid, terpenoid, saponin yang memiliki aktivitas antioksidan. Uji aktivitas antioksidan ekstrak kulit durian diperoleh nilai IC50 sebesar 57,5487 tidak memenuhi standart. Hasil uji aktivitas antioksidan vitamin C diperoleh nilai IC50 sebesar 15,9617 memenuhi standart.en_US
