  • What is antioxidant Rd (TMQ)?
  • It acts as an antioxidant. It can be used as a general purpose ammonia anti aging agent. It is suitable for full-steel, semi steel and radial tires. ANTIOXIDANT RD (TMQ) (First) is designed for use in rubber tube, rubber overshoes and general industrial rubber products.
  • What is the Order of decreasing antioxidant activity in ethanolic extracts?
  • The order of decreasing antioxidant activity in the ethanolic extracts of plants was V. candicans > S. vermiculata > C. dioscoridis > P. harmala with values of 368.2, 216.9, 165.0, and 92.9 μg ascorbic acid equivalent/g d.wt, respectively.
  • How to measure electron donation ability of natural products?
  • The electron donation ability of natural products can be measured by DPPH assay. The assay is based on scavenging of DPPH through the addition of a radical species or antioxidant that decolorizes the DPPH solution. The degree of color change is proportional to the concentration and potency of the antioxidants.
  • Which plant extract has the lowest IC50 against DPPH?
  • Moreover, the extract of Suaeda vermiculata exhibited the lowest half maximum inhibitory concentration (IC50) against DPPH, thus indicating its highest effectiveness. All studied plant extracts decreased the viability of HepG2 cells, in a dose- and time-dependent manner, and the lowest IC50 was for Suaeda vermiculata.
