Pharmacognostic, Isolation and Physicochemical Characterization of American Aloe (Agave americana) Cellulose Powder

Abstract

This study investigates the pharmacognostic properties, isolation, and physicochemical characterization of cellulose powder derived from Agave americana (American aloe). Pharmacognostic evaluations included macroscopic observations, geographical distribution, and botanical authentication. Isolation and purification methods focused on delignification and elimination of impurities using sodium hydroxide and bleaching agents. Purified cellulose powder was characterized for phytochemical and physicochemical parameters such as solubility, thermal stability, swelling index, water uptake capacity, and micromeritic properties. Phytochemical tests revealed the absence of lignin and the presence of cellulose post-purification. Physicochemical properties indicated improved thermal stability, porosity, and flow properties upon the addition of glidants. This comprehensive study highlights the potential applications of purified cellulose in pharmaceutical formulations.
