Abstract :
This study aims to determine the ability of green eggplant (Solanum
melongena L.) to reduce glucose levels so that it can be potential as an in vitro
antidiabetic using the Nelson somogyi method. Sample extraction using
maceration method with 96% ethanol solvent. The ethanol extract of green
eggplant fruit was tested by phytochemical screening. The antidiabetic potential
test was carried out by measuring the decrease in glucose levels using Nelson's
reagent and the absorbance was measured using a UV-Vis Spectrophotometer at
the 25th minute operating time and a maximum wavelength of 746 nm. The
results showed that the ethanol extract of green eggplant (Solanum melongena L.)
contained flavonoids, alkaloids, tannins, saponins and phenols. The ethanol
extract of green eggplant fruit has the potential to be antidiabetic because at
concentrations of 5, 20, 15, 20, and 25 ppm it can reduce glucose levels with an
average EC50 value of 23.438 ppm and a KV value of 0.373%.
