Abstract

Abstract: Microcrystalline cellulose (MCC) was obtained by the hydrolysis of cellulose in Dioscorea nipponica Makino's residue after dioscin was extracted. Its content and LODP were analyzed with chemical methods. The physicochemical properties of MCC of D.nipponica were studied by means of scanning electronic microscopy (SEM) and X-ray diffraction. The results snowed that in the sample prepared from D.nipponica, the MCC content is 91.7%, LODP is 164, crystallinity is 77.1% and average grain size is 23.21 nm. All of these parameters are corresponded with the results of 101QD microcrystalline cellulose provided by Mingtai Co. in Taiwan.

Key words: Dioscorea nipponica Makino, microcrystalline cellulose, preparation, physicochemical properties
