Microcrystalline cellulose is the most used material for medicine, which able to be found in fibrous plants. Microcrystal celluloses are being used as filler or binder in dosage formulas in tablets and capsules. This research aimed to produce microcrystalline cellulose from ramie based on pharmaceutical grade parameters. Research method include hemp fiber preparation, α-cellulose isolation, microcrystalline cellulose production, and microcrystalline cellulose characterization which compare with Avicel® PH 102 . Result shown microcrystalline cellulose yield is 57.26%. The result of physicochemical characterization that can comply the specifications of pharmaceutical grade as a pharmaceutical excipient.  Keywods :  Microcrystalline cellulose, Ramie, physicochemical, pharmaceutical grade.

Microbial cellulose, an exopolysaccharide produced by bacteria, has unique structural and mechanical properties and is highly pure compared to plant cellulose. Present study represents isolation, identification, and screening of cellulose producing bacteria and further process optimization. Isolation of thirty cellulose producers was carried out from natural sources like rotten fruits and rotten vegetables. The bacterial isolates obtained from rotten pomegranate, rotten sweet potato, and rotten potato were identified asGluconacetobactersp. RV28,Enterobactersp. RV11, andPseudomonassp. RV14 through morphological and biochemical analysis. Optimization studies were conducted for process parameters like inoculum density, temperature, pH, agitation, and carbon and nitrogen sources usingGluconacetobactersp. RV28. The strain produced 4.7 g/L of cellulose at optimum growth conditions of temperature (30°C), pH (6.0), sucrose (2%), peptone (0.5%), and inoculum density (5%). Characterization of microbial cellulose was done by scanning electron microscopy (SEM).

The purpose of this study was to prepare and characterize solid dispersions of the antibacterial agent Cefdinir with PEG 4000 and PVP K-30 with a view to improve its dissolution properties. Investigations of the properties of the dispersions were performed using release studies, X-ray powder diffraction (XRD) and Fourier transform infrared (FTIR). The results obtained showed that the rate of dissolution of Cefdinir was considerably improved when formulated in solid dispersions with PVP K-30 and PEG 4000 as compared with pure drug and physical mixtures. The results from XRD studies showed the transition of crystalline nature of drug to amorphous form, while FTIR studies demonstrated the absence of drug-carriers interaction.
