The improved preparation of D-glucosamine hydrochloride from waste hypha residue of citric acid was reported. The use of HCl and acetic acid system as an acid hydrolysis reagent led to a significant increase in the yield of D-Glucosamine hydrochloride (GluHCl). Other effects of various factors on the preparation of GluHCl were also investigated: temperature of acidification, HCl concentration, and reaction time. The experimental conditions were optimized by a L9 (34) orthogonal array design (OAD) with four factors at three levels using statistical analysis. Under optimal conditions, the yield of GluHCl reached 5.2%.

Nanoscale lignin was successfully prepared with a supercritical antisolvent (SAS) apparatus using acetone as a solvent and superciritical carbon dioxide as an antisolvent. Four factors were studied and optimized by a four-level orthogonal array design (OAD). According to analysis of variance, precipitation pressure had a significant effect on mean particle size. The optimal conditions are as follows: precipitation temperature 35 °C, precipitation pressure 30 MPa, temperature difference +10 °C and concentration of lignin solution 0.5 mg/mL. The micronized lignin under the optimal conditions was characterized by Scanning Electron Microscopy (SEM), Fourier-transform Infrared Spectroscopy (FTIR), Dynamic Light Scattering (DLS) and X-Ray Diffraction (XRD) analyses. The results showed the mean particle size of micronized lignin was 0.144 ± 0.03 μm and had no degradation. The solubility of micronized lignin was improved significantly in distilled water.

This research focused on BDF production from Jatropha seed oil and evaluation of its exhaust gas on the diesel engine in order to produce and confirm the environmental benefit of BDF. This report showed the results of research on BDF production from Jatropha seed oil and engine emissions from blend of diesel fuel and BDF from Jatropha oil. A maximum of 78% biodiesel yield was found at 2.25%w/w catalyst KOH, the optimum molar ratio of Jatropha oil to methanol of 1:6, at a reaction temperature of 550C in 45 minutes. The use of BDF blends in conventional diesel engine results in substantial reduction in emission of hydrocarbon CxHy, carbon monoxide CO and sulfates SO2, whereas NOx emission increases a little. The reason for reducing of CxHy, CO and SO2 emission and increasing NOx emission with biodiesel mixtures was mainly due to the presence of oxygen in their molecular structure.

This study proposes the wear characteristics of the jatropha oil consisting ofhBNas nanoparticles. During the test, speed was varied at different rpm. The nanoparticles of 0.3% to 1.2% was mixed to the jatropha seed oil. All the experiment was accomplished on pin on disc tribometer. It has been observed that the nanoparticles of 0.6% ratio shows minimum coefficiecnt of friction and wear during all conditions. In terms of sliding speed, maximum wear of the material occurred at lower speeds for all the samples.

Biodiesel is derived from triglycerides by transesterification reaction with alcohol (ethanol or methanol), and has classified as a renewable, biodegradable, and nontoxic fuel. Several methods for biodiesel production have been developed, among which transesterification using alkali-catalysis gives high levels of conversion of triglycerides to their corresponding methyl esters in short reaction times. This study was conducted to extract the neem and Jatropha oil for the production of biodiesel using alkali-catalyzed reaction The samples were subjected to reaction with sodium hydroxide (NaOH), 0.2:1 w/v methanol (MeOH) to oil mole ratio, reaction temperature of 6°C, and 30 min reaction time. The final biodiesel yield obtained was 47.5% and 45.5% from the neem and the jaropha oil sample respectively. The basic physicochemical properties of the jatropha methyl ester produced from both jatropha oil samples were found to be within the ASTM D6751 specified limits.

Background: A better understanding of the biopharmaceutical and physicochemical properties of drugs and the pharmaco-technical factors would be of great help for developing pharmaceutical products. But, it is extremely difficult to study the effect of each variable and interaction among them through the conventional approach Objective: To screen the most influential factors affecting the particle size (PS) of lipid nanoparticle (LNPs) (solid lipid nanoparticle (SLN) and nanostructured lipid carrier (NLC)) for poorly water-soluble BCS class-II drug like tamoxifen (TMX) to improve its oral bioavailability and to reduce its toxicity to tolerable limits using Taguchi (L12 (2 11)) orthogonal array design by applying computer optimization technique. Results: The size of all LNPs formulations prepared as per the experimental design varied between 172 nm and 3880 μm, polydispersity index between 0.033 and 1.00, encapsulation efficiency between 70.8% and 75.7%, and drug loading between 5.84% and 9.68%. The study showed spherical and non-spherical as well as aggregated and non-aggregated LNPs. Besides, it showed no interaction and amorphous form of the drug in LNPs formulation. The Blank NLCs exhibited no cytotoxicity on MCF-7 cells as compared to TMX solution, SLNs (F5) and NLCs (F12) suggests that the cause of cell death is primarily from the effect of TMX present in NLCs. Conclusions: The screening study clearly showed the importance of different individual factors significant effect for the LNPs formulation development and its overall performance in an in-vitro study with minimum experimentation thus saving considerable time, efforts, and resources for further in-depth study.

An orthogonal array design was employed for optimizing the supercritical CO2 extraction of Rhizoma Atractylodis Macrocephalae. The extraction was performed at temperature from 40 to 60oC, pressure from 15 to 35MPa, extraction time varying from 30 to 90min and particle size spanning from 20 to 80 mesh. The results reflect that the extraction yield is more significantly influenced by the extraction time, pressure and particle size but less by temperature. The experiments show that the extraction yield obviously increases with increasing pressure, different from the literatures. In terms of the sample origin, a comparison shows that outstanding differences exist among the extraction yields from different sources.
