“…X-ray diffraction (XRD) was carried out to study the crystallinity of the MCC of rice husk. In the X-ray patterns, three main reflections at 2θ=14.70°, 22.09° and 34.24° were observed for the sample, indicating that the rice husk microcrystalline cellulose and were cellulose I type (7). Furthermore, the similar patterns of X-ray diffraction of standard microcrystalline cellulose reported in literature by (8) demonstrated that hydrolysis did not change the cellulose structure of the rice husk MCC, which was in accordance with the results of FT-IR.…”

Microcrystalline cellulose (MCC) was prepared from rice husk by subjecting it to alkaline pretreatment, delignification, bleaching, and hydrolytic operations. MCC was also prepared from cotton wool and used as a reference because of its high cellulose content to estimate a relative yield and quality of the MCC produced from rice husk. The characteristic morphological feature was established by scanning electron micrograph (SEM) and the crystallinity of the Rice husk Microcystalline cellulose was further confirmed using the X-RD technique; the functional group was confirmed by the Fourier transform infrared (FTIR) spectroscopic method with characteristic absorption bands of ;-OH stretching at 3416 cm -1 ; C-H stretching at 2918 cm -1 ; -OH bending at1377 cm -1 ;, 1159 cm -1 ; and C-O-C pyranose ring skeletal vibrations at 1026-1033 cm -1 , and the thermal stability was determined from thermogravimetric analysis (TGA). The characterized MCC of rice husk was applied as a stationary phase in Preparative Thin Layer Chromatography gave good separation (PTLC).

“…There are two significant weight loss stages below 600 °C in the TG curve of MC (curve a). The initial weight loss happened around 100 °C, which is due to the evaporation of physically adsorbed and hydrogen bond-linked water molecules [ 29 ]. A large rapid decrease of the weight occurred between 250 and 400 °C in the second stage.…”

Cellulose has been widely used in the biomedical field. In this study, novel cellulose aerogels were firstly prepared in a NaOH-based solvent system by a facile casting method. Then amoxicillin was successfully loaded into cellulose aerogels with different loadings. The morphology and structure of the cellulose aerogels were characterized using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The drug release and antibacterial activities were also evaluated. The drug release results showed that cellulose aerogels have controlled amoxicillin release performance. In vitro antibacterial assay demonstrated that the cellulose aerogels exhibited excellent antibacterial activity with the amoxicillin dose-dependent activity. Therefore, the developed cellulose aerogels display controlled release behavior and efficient antibacterial performance, thus confirming their potential for biomedical applications.

“…Moisture content is also critical property as it has been seen that it can influence compaction properties, tensile strength, and viscoelastic properties of MCC in tablets. When the moisture level is lower than 3% it won't affect compaction properties of MCC, however, increase in moisture content to an optimum level will eventually increase the strength of the tablet, that might be because of decrease in interparticular distance and increase in intermolecular attraction forces [25]. More than 3% of water content in microcrystalline cellulose would disrupt hydrogen bonds that crosslink hydroxyl groups on the cellulose chain, resulting in a strength decrease [5].…”

Microcrystalline cellulose (MCC) is a versatile and frequently used material in different industries such as pharmaceutals production, medical, cosmetics and food industry. It is inert, economic, compatibility, compatibility, non-toxicity, biodegradability, good mechanical properties, high surface area, variety and availability of different grades and biocompatibility has made it very popular. A number of research has been done on MCC to isolate it from different plant sources that are economical and eco-friendly. MCC is extracted from α cellulose that is abundant in nature as most of MCC is produced from wood. However, new eco-friendly sources with changes in methods of isolation have been applied for the production of MCC. In this review MCC isolated from different plant-based resources, extraction process parameters, origin of raw material and its influence on critical material attributes of MCC has been outlined and discussed thoroughly. Since these critical material attributes have a significant effect on tablet making process parameters (compressibility, compactibility and etc) and its post compression characters.Keywords: Microcrystalline cellulose, isolation, characterization, raw material, tablet
