A method of assay for the estimation of sulphadimidine in tablets

A simple and rapid titrimetric method (Back Titration) was used in the assay of Sulphadimidine in commercial tablets. The method involves alkaline hydrolysis of Sulphadimidine to form the corresponding acid. This was followed by back titration of the excess alkali using phenolphthalein as indicator. The results of this assay method were compared with those obtained from the official nitrite titration method. Both methods yielded similar results with high percentage recoveries. The proposed method gave results that agree well with the labeled contents.

Studies on the physicochemical properties and fatty acid composition of the oil from ripe plantain peel (Musa paradisiaca)

Oil extracted from ripe peel of Musa paradisiaca (plantain) was analyzed for physicochemical properties and fatty acid constituents using standard methods. The results revealed that the acid value, peroxide value and specific gravity were significantly (p<0.05) higher than those of soybean oil whereas saponification value, iodine value, ester value, boiling, smoke, flash and fire points were significantly lower than in soybean oil. The percentage yield of the oil from the peel of M. parasidiaca fruit was 6%.
