Overview

Study assesses antioxidant activity of neem leaf extract via DPPH, ABTS, and FRAP methods, indicating its potential health benefits.

Key Points

  • The methanolic extract of neem leaves showed strong antioxidant activity in the DPPH assay.
  • DPPH assay resulted in an IC₅₀ value of 54.91 ppm, indicating effective free radical scavenging.
  • Extraction used Ultrasound-Assisted Extraction, assessing multiple methods to evaluate antioxidant capacity.
  • Findings suggest the primary antioxidant mechanism of neem extract relies on hydrogen atom transfer rather than electron transfer.
