Extraction of antioxidants from fermented samples by using sprout culture of Orthosiphon aritatus (IOSC):

  • Grow culture to ferment samples

  • After two weeks of growing culture, harvest and lyophilize samples

  • Ground to a fine powder

  • Extract using 70% methanol

70 % methanol extraction method produces the highest yield of total phenolics, flavonoids, flavonols and rosmarinic acid; and consequently exhibited the strongest antioxidant activity (DPPH, TEAC and SOD-like activity).

Best regards!
