Objective: The main objective of the present work is to screen the antioxidant and antibacterial activity of various extracts obtained from flowers of belonging to the family. Calotropis gigantea Apocynaceae Materials and Methods: Both organic (Pet ether, Benzene and Acetone) and aqueous (Hydroalcohol) extracts of flowers Calotropis gigantea were prepared by using Soxhlet and cold maceration technique respectively. The extracts were concentrated using rotary evaporator. By using invitro paradigms, DPPH, nitric oxide and hydroxyl free radical scavenging activity were carried out. Meanwhile all the extarcts were subjected for antibacterial activity using various gram+ive and gram-ive bacterias in the substrate medium of Muller agar media with Diffusion assay method. In the antioxidant Results: activity, Pet ether extract showed a significant activity than other extracts. Also increase in concentration of the extract showed an increase in inhibition of the generfated free radicals. At most the pet ether extract at a higher concentration of 320 mcg/ml showed an increased inhibition of DPPH (73.5±0.2%), Nitric oxide (56.1±0.3%) and Hydroxyl (78.1±0.8%). Meanwhile antibacterial activity of hydroalcohol extract showed an increased zone of inhibition for various organisms used in this method than other extracts and significant to the standard, Pefloxacin. Conclusion: It was investigated that antioxidant activity showed a potential inhibition on generated free radicals and both gram+ive and gram-ive bacterial strains. Further studies are needed to evaluate the structural elucidation of active ingredients present in those extracts.
This study focuses on the conversion of chicken fat into chicken fat methyl ester (CFME) and its use in the diesel engine. Baseline fuel i.e., diesel and chicken fat biodiesel are the fuels tested to study their effect on the performance and emission characteristics of diesel engines. To enhance the performance and emission characteristics, ethanol up to 20% is added as an additive to the chicken fat biodiesel. The physiochemical properties revealed that the fuel blends properties are closer to the diesel fuel. The experimental investigations revealed that additive blended biodiesel enhanced the performance by reducing the brake-specific fuel consumption and increasing the brake thermal efficiency. Moreover, the emissions are considerably reduced by the additive blended chicken fat biodiesel. Therefore, chicken fat biodiesel can be considered as a substitute fuel to be used in the diesel engine without any modifications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
