The ethanolic extract of M.Oleifera root bark is shown to be rich in nutrients, owing to the presence of essential phytochemicals in the root bark. The phytochemicals or secondary metabolites of the ethanolic extract of the root bark were screened and identified. Also, acute toxicity study of the ethanolic extract of the root bark was carriedout in Albino Rats according to Institutional Animal Care and Use (IACU) guidelines. The fresh M.Oleifera root was harvested at the inception of the rainy season at Pil Gani District of Langtang North LGA and excess soil washed off as the root bark was properly peeled, air dried, pulverized to powdered form and stored for subsequent use. Serial extractions using water, acetone, ethanol, and ethyl acetate were carriedout by Simple Maceration. The ethanolic extract was seen to have the best yield of the phytochemicals qualitatively identified as tannins, saponins, carbohydrates, flavonoids, alkaloids, steroids, terpenes, cardiac glycosides and anthraquinones. Acute toxicity test was determined by Lorke’s method and the LD50 was shown to be at the highest limit dose of 5000mg/kg, which signifies that the extract is non toxic at such single dosage. The ethanolic M.Oleifera root bark extract contains nutritive phytochemicals with vast medicinal uses. No sign of acute toxicity was observed on oral administration as the median lethal dose was shown to be safe at the highest limit single dose of 5000mg/kg.","PeriodicalId":102130,"journal":{"name":"Nigerian Journal of Chemical Research","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135756623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plantain peels were carbonized, activated with phosphoric acid and the activated carbon was separated into various proportions and impregnated with various percentages of chitosan to make the composite biosorbents. Deproteinization, deminerization, and deacetylation techniques were used to extract chitosan from a snail shell. Fourier transform infrared (FTIR), energy dispersive X-ray (EDAX), X-ray diffraction (XRD), scanning electron microscopy (SEM) and Brunauer-Emmett-Teller (BET) techniques were used to analyze the adsorbents. Effects of process parameters: pH of wastewater, adsorbent dosage, temperature, initial concentration and contact time were determined. In the blending ratios of the biosorbents, 75% oxalic acid modified chitosan-25% activated plantain peel (CHT-APP5) was best blend and the optimum process variables for the removal efficiency were time (60-65mins), adsorbent dosage (2-2.125g/dm3), pH(6-6.5), initial concentration of wastewater(20-85mg/dm3) and temperature (308-325K). The results obtained showed that the maximum adsorption capacities of 90.9090, 55.5556 and 142.8571mg/g for Cr(VI) while 62.500, 83.3333 and 43.4783mg/g Cd(II) were obtained for CHT, APP1 and CHT-APP5 respectively. The results showed that blends have the potential to be used as alternative efficient low-cost biosorbent in the removal of heavy metals from wastewater.","PeriodicalId":102130,"journal":{"name":"Nigerian Journal of Chemical Research","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135756626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The extract was obtained by fractionating crude ethanol CLR extract in order of increasing polarity, n-Hexane, chloroform, ethylacetate and ethanol. The GC-MS analysis was carried out on GC system comprising Gas Chromatograph interfaced to Mass Spectrometer (GC-MS) instrument. The bioactive compounds obtained were compared with database of spectrum of known components stored in the gas chromatography-mass spectrometry library. The GC-MS analysis of ethanol extract of CLR revealed the presence of androst-4-en-9-thiocyanomethyl-11-ol-3,17-dione a steroid which is a precusor for androgen and estrogen production. As well as cyclooctasiloxane hexadecamethyl and octasiloxane hexadecamethyl in which both of them contain silicon an essential trace element for collagen and bone formation .The presence of these compounds validates the use of ethanol extract of CLR as a good antioxidants, antibacterial agents and stimulant in precursor of male reproductive hormone production.

G. lotoides leaves was extracted in acetone-hexane by cold maceration and concentrated in vacuo. The GC–MS analysis revealed the presence of the following phyto-compounds: 9-Octadecenoic acid, (E) (Z; 242.3975, RT: 16.663; 49.11%), n-Hexadecanoic acid (Z; 256.42, RT: 15.030, 25.58%), Octadecanoic acid (Z; 284.47, RT: 16.785; 6.80%), Stigmasterol (Z; 412.69, RT: 20.929; 5.25%) and Ergost-5-en-3-ol, (3.beta) (Z; 400.68, RT: 19.962; 2.72%) among others.

There is a need to look for low-cost filters to address the scarcity of water in rural areas surrounded by industrial wastewater. The present study investigates the use of low-cost filter for purification of industrial wastewater. Filters made from cow bone (CBF) and saw dust (SDF) were used to remove some impurities in wastewater. Wastewater from Ore Industrial Estate, Ondo State, Nigeria, are collected and ran through the filter, the physicochemical parameters were determined using standard method while metal content were determined using Atomic Absorption Spectrophotometer. The filter content before and after use were analyzed using Fourier Transformed Infrared (FTIR) Spectrometer. CBF reduces Electrical Conductivity (EC), Chloride and chemical oxygen demand COD of the wastewater appreciably. It removed 74 %, 70 %, 65 %, 68 % and 81 % of Mn, Ni, Cd, Pb, and Zn respectively while SDF removed 8 %, 14 %, 26 %, 17 % and 28 % of the same elements respectively. The C = O stretch was recorded at wavelength of 1646.31cm-1 before filtration and broad at 1640.19 cm-1 after filtration in CBF. Broad OH peak was recorded at 3750.84 cm−1 before filtration and 3674.41 cm−1 after filtration for saw dust filter (SDF). It was concluded that the spectral showed that some materials are removed from the water. The cow bone filter is more efficient than the saw dust filter.","PeriodicalId":102130,"journal":{"name":"Nigerian Journal of Chemical Research","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128580432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The extract was also found to cause leakages of cellular materials such as potassium ions, sodium ions, protein and nucleic acids from the test bacteria which led to the loss of cell viability. The ethyl acetate sub-fraction of the extract was analyzed by GC-MS and FTIR analysis and the result revealed the presence of Phytochemicals such as 1, 2-Benzenedicarboxilic acid mono (2-Ethylhexyl) ester, Columbin, 2-(6-Methylpyridin-2-ylmethyl) cyclohexane, 2(1H) Naphthalenone,3,5,6,7,8,8a-hexahydro-4,8a-dimethyl-6-(1-methylethenyl) which have all been reported to possess antibacterial activity against both gram-positive and gram-negative bacteria. The result of this study will contribute to the baseline data on the pharmacodynamics of the extract if applied as herbal medicine for human treatment thereby reducing the dosage and period of treatment.
