The antioxidant and free-radical scavenging activity of the obtained oils and extracts were tested by means of 1,1-diphenyl-2-picrylhydrazyl radical (DPPH+) assay, [(2,2ˊ-azino bis-(3-ethylbenzothiazoline-6-sulfonic acid)] (ABTS), nitric oxide and ferric reducing power assays. The oils and extracts showed DPPH radical scavenging ability, but not as high as the standard drugs. The base extract showed a higher reducing power than the standard drug, rutin. There were significant differences in the phytochemicals contents of the various leaf extracts. The acetone extract has the highest flavonol, proanthocyanidin, and alkaloid contents. The ethanol extract showed the highest amount of phenolic content with the acid extract, having the least. Thin layer chromatography (TLC) and column chromatography was employed to obtain different fractions of extracts using four eluent solvent systems of varying polarities: toluene, petroleum ether, hexane and ethyl acetate and sprayed with anisaldehyde. A single, visible spot of B-fraction was developed, collected and analyzed as 1-methyl-2,4,5- trinitroimidazole with renown valuable properties.]]> Tue 15 Jun 2021 15:58:29 SAST ]]> An investigation of source rocks and depositional environments on acid mine drainage in South African coal mines: a comparison of the main Karoo basin and sub-basins. http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:43139 Tue 07 May 2024 08:41:04 SAST ]]> Assessing public administration implications of the use and disposal of agro-chemicals in A2 farms in Zimbabwe : a case study of Chirumhanzu District http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:65471 Tue 04 Jul 2023 11:14:58 SAST ]]> A critical assessment of economic policies and their impact on entrepreneurship development in South Africa: a case of Khayelitsha Township in Cape Town http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:65236 Mon 26 Jun 2023 22:39:16 SAST ]]> Modification and application of the decentralised wastewater treatment technology for greywater treatment to reduce water needs http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:45338 Mon 22 Nov 2021 15:20:03 SAST ]]> An analysis of schooling outcomes in the Eastern Cape, using production function approach http://vital.seals.ac.za:8080/vital/access/manager/Repository/vital:65656 Mon 10 Jul 2023 11:30:30 SAST ]]>
