Isolation and characterization of microcrystalline cellulose obtained from palm nut (Elaeis guineensis) fibres

Abstract

In this study, microcrystalline cellulose, coded MCC-PNF, was obtained from palm nut (Elaeis guineensis) fibres. MCC-PNF was examined for its physicochemical and powder properties. The powder properties of MCC-PNF were compared to those of the best commercial microcrystalline cellulose grade, Avicel PH 101. The extraction yield of MCC-PNF was approximately 8% w/w. The cellulose material was composed of irregularly shaped fibrous cellulose particles and has a moisture content of 5.6% and total ash of 0.21%. The true density was 1.54 g/cm³. The flow indices showed that MCC-PNF flowed poorly. The hydration and swelling capacities were 3.82 and 56.8% respectively. The study revealed that the cellulose material comparesfavourably with Avicel PH 101 and conformed to official requirements specified in the British Pharmacopoeia and Handbook of Pharmaceutical Excipients for microcrystalline cellulose.
