Anthocyanin Encapsulated Nanoparticles as a Pulmonary Delivery System

Table 1

The physical and chemical properties of anthocyanin-loaded nanoparticles prepared using PEG-PLGA, MDX, or CMC.

Encapsulant	Core content	Particle size (nm)	PDI	Zeta potential (mV)	Total yield (%)	TPC (mg GAE/g DW)	FRAP (μM TE/g DW)	IC50 (mg/mL DW)
CMC	Empty	97–322				—	—	—
	HB	163–170
MDX	Empty	50–465				—	—	—
	HB	116-420						ND
PEG-PLGA	Empty	120-310				—	—	—

Data represents nanoparticles HB: polymer ratio of 1 : 10. Total yield (%) = weight of nanoparticles/weight of the material used to prepare nanoparticles ×100. PEG-PLGA : polyethylene glycol-poly(lactide-co-glycolide); MDX: maltodextrin; CMC: carboxymethyl chitosan; PDI: particle distribution intensity; TPC: total phenolic content; FRAP: ferric reducing antioxidant power assay; DW: dry weight; empty: anthocyanin-free nanoparticles; HB: haskap berry extract; GAE: gallic acid equivalent; TE: Trolox equivalent; ND: not detected.
