The harvested Mitracarpus Scaber plants are identified in the national herbarium and registered under the number AA. 6252/HLB. During this work, three crude extracts are prepared from three organic solvents, namely dichloromethane; ethanol and hydro ethanol in 50/50 v/v proportion. The respective alkaloid extracts obtained from the corresponding crude extracts served as substrates for the hemi synthesis of thiosemicarbazone totals from thiosemicarbazides. The three hemi-synthesis products obtained were tested on eight (08) strains of germs, namely E. coli ATCC 25922, S. aureus ATCC 25923, E. faecalis ATCC 22921, P. aeruginosa ATCC 27853, C. albicans ATCC 10231, S. typhi, K. pneumoniae and Dermatophilus 146. The ethanolic extract of thiosemicarbazones exhibited the best bioactive activity and was found to be the most selective. By a series of bio guided chromatographies: TLC thin layer chromatography; CPA atmospheric pressure chromatography and medium pressure liquid chromatography. MPLC (medium pressure liquid chromatography), separation on dextran gel: Sephadex® LH20). The use of available spectral data, cross-checked with that of the literature, made it possible to identify and purify three (03) molecules of thiosemicarbazones, making it possible to study the biological activity of their combination.
Peer Review History:
UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
