Presently analytical community put interest in the research area of non-hazardous and eco-friendly practices to develop various green chromatographic methods for routine quality analysis. High cost of phytochemical analysis and uses of hazardous chemicals with high-end sophisticated instrument, the attempt made to develop a simple analytical method for multiple samples with short time and less uses of solvents. A HPTLC method was developed for simultaneous determination of biological important constituents like β- sitosterol, taraxerol, clitorienolactone B and β-sitosterol glycoside from Clitoria ternatea Linn. The proposed method was validated and satisfied the ICH guidelines to demonstrate that the method is adaptable for its intended purpose. The method is simple, sensitive and economic it therefore embraces potential for detection, monitoring, and simultaneous quantification of the four bioactive compounds for C. ternatea and could also be apply to other species Thu, 16 Mar 2023 00:00:00 GMT http://10.9.150.37:8080/dspace//handle/atmiyauni/1822 2023-03-16T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/1816 Title: Hierarchically porous PTSA with Si species for efficient and sustainable conversion of non food castor oil to biodiesel Authors: Savaliya, Mehulkumar L; Tank, Ravi S; Dholakiya, Bharatkumar Z Abstract: Catalysis is the vertebra of most of commercial processes, which utilizes chemical reactions to transform reagents into value added chemicals. Biodiesel synthesis from animal fats and edible vegetable oils via transesterification over homogeneous catalysts is recently taken into account of untenable by the emerging biofuel industries, particularly by virtue of food vs. Fuel counteraction, economic and environmental challenges blended with the feedstocks as well as catalytic systems, respectively. Therefore, present efforts concern with the preparation of a novel PTSA-Si catalyst and its relevance for biodiesel synthesis from non-food castor oil. It has been manifested from the experimental outcomes, the most relevant reaction parameters are, 5 % PTSA-Si (w/w), 65 °C reaction temperature, 1:11 O:M molar ratio and 10 h reaction time for Title Page 98.56 % biodiesel yield. The PTSA-Si was appropriately analyzed using FT-IR, SEM, XRD, BET, TGA-DTA and TPD-NH3 analysis. Since, castor oil and castor biodiesel were analyzed using FT-IR, 1H &13C-NMR analysis. Besides, biodiesel physico-chemical properties were predicted and associated with ASTM fuel standards Sat, 01 Jan 2022 00:00:00 GMT http://10.9.150.37:8080/dspace//handle/atmiyauni/1816 2022-01-01T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/1815 Title: Eco-friendly process for preparation of biodiesel from WFO over MTSA-Si catalyst: An innovative approach for the utilization of side product Authors: Savaliyaa, Mehulkumar L; Dholakiya, Bharatkumar Z Abstract: Present work aimed for the synthesis of a promising MTSA-Si catalyst and its application for biodiesel preparation using WFO. It has been illustrated from the experimental results, the most favorable reaction conditions for the biodiesel preparation using WFO are (i) 1:10 oil to methanol molar ratio, (ii) 5% MTSA-Si catalyst (w/w), (iii) 130 °C reaction temperature and (iv) 10 h reaction time, for the 98.22% yield of biodiesel. The side product raw glycerin was further transformed into the triglycerides over MTSA-Si catalyzed lauric acid esterification. The fuel properties of biodiesel were estimated and correlated fuel standards Tue, 27 Mar 2018 00:00:00 GMT http://10.9.150.37:8080/dspace//handle/atmiyauni/1815 2018-03-27T00:00:00Z http://10.9.150.37:8080/dspace//handle/atmiyauni/1813 Title: “Click Chemistry” Inspired Synthesis and Antimicrobial Evaluation of 1,2,4-triazolo[4,3-a]pyridine linked 1,4-disubstituted 1,2,3-triazole Derivatives with Amide Functionalities Authors: Parmar, Rahul V; Vadodaria, Milan S; Gajera, Prashant S Abstract: In an attempt to rationalize the search for new potential antimicrobial agents, a new series of 1,2,4-triazolo[4,3-a] pyridine linked 1,4-disubstituted 1,2,3-triazoleswith amide linkage has been synthesized by the cyclization of 1,2,4-triazolo[4,3-a]pyridine-based alkynes and 2-azido N-phenylacetamide in the presence of CuSO4 as catalyst through ‘‘Click Chemistry” approach. The newly synthesized scaffolds have been evaluated for their antimicrobial potential using eight microbial strains such as Escherichia coli, Pseudomonas aeruginosa, Enterobacter aerogenes, Bacillus megaterium, Staphylococcus aureus, Bacillus subtilis, Aspergillus Niger, and Aspergillus flavus. Results revealed that all synthesized scaffolds displayed superior activities than the standard drugs against various microbial strains. The synthesized compounds showed potential antimicrobial activity against Gram-positive, Gram-negative bacteria, and fungi Wed, 17 Apr 2024 00:00:00 GMT http://10.9.150.37:8080/dspace//handle/atmiyauni/1813 2024-04-17T00:00:00Z
