Antioxidant Effects of Quercetin and Catechin Encapsulated into PLGA Nanoparticles

Table 1

Mean particle size, polydispersity index, Zeta potential, and encapsulation efficiency of the PLGA NPs and quercetin/catechin-loaded PLGA NPs.

NPs		Particle size (nm)	Polydispersity index	Z potential (ζ) (mV)	E.E. (%)
	Placebo	387.27±14.5^a	0.173±0.092^a	−31.47±1.01^a	—
PLGA	Quercetin	399.67±10.86^a	0.262±0.16^b	−44.67±0.48^b	79.84±2.5^a
	Catechin	410.59±9.66^a	0.39±0.125^c	−29.83±0.21^a	76.14±6.13^a

Results are expressed as the mean ± S.E. of three replicates with three repetitions. Different letters indicate significant difference (𝑃<0.05) between rows compared with placebo PLGA.
