PERBANDINGAN METODE EKSTRAKSI MASERASI DAN SOKLETASI TERHADAP AKTIVITAS ANTIOKSIDAN EKSTRAK ETANOL DAUN JAMBU BOL (Syzygium malaccense L.)
Abstract: Malay apple
(Syzygium malaccense L.) is a plant that can be used for treatment.
Antioxidants have the activity to reduce free radical compounds which is one of
the causes of the emergence of various diseases in humans. The purpose of this
study to determine the comparison of methods of maceration and socletation
extraction of antioxidant activity of malay apple leaf. Research stages include
sampling, plant determination, making of simplisia, maceration extraction and
socletation with 70% ethanol solvent and determine the antioxidant activity by
UV-Vis spectrophotometry with DPPH (1,1-diphenyl-2-picrylhydrazyl) as free
radical. The parameter is IC50 value that is the concentration of antioxidant
compound which can cause 50% loss of DPPH free radical activity. Although both
methods show very strong antioxidant activity, it can be concluded that the
difference in extraction methods has an effect on the antioxidant activity
produced. The results of antioxidant activity test showed that socletation
methods gave an average IC50 value of 37.67 ppm, this value is higher than
maceration methods with an average IC50 value of 47.80 ppm. Malay apple leaf
has the potential as a natural antioxidant, although it has a lower IC50 value
than vitamin C which is 9.72 ppm.
