After drying, powdered nanoparticles were produced. Eq. ( 1) was used to calculate the process yield.
where MT is the mass of guar gum plus ethyl cellulose plus the mass of CAPC in the formulation, Y (%) is the process yield, and MNP is the mass of nanoparticles recovered after drying 18 .
The drug loading capability of GG-EC-CAPC nanoparticles was evaluated by thoroughly extracting the drug from a speci ed quantity of nanoparticles in pH 6.8 phosphate buffer, succeeded by centrifugation at 10,000 revolutions per minute for 10 min 19 (link) . The concentration of the drug in the supernatant was determined utilizing a UV-visible spectrophotometer at a wavelength of 240 nm.
