Antioxidants are chemicals that possess bioactive constituents which usually allow them to fight against free radicals. Antioxidant and phytochemicals properties of the leaves Synsepalum dulcificum were investigated using ethyl-acetate, ethanol methanol extracts. 2, 2-diphenyl-picrylhydrazyl (DPPH) scavenging activity, total antioxidant ferric reducing power (FRAP), flavonoid phenolic content w...

The results of our previous investigations on extracts of selected marine algae showed that Caulerpa peltata and Padina gymnospora had more promising antiproliferative and antioxidant activities than Gelidiella acerosa and Sargassum wightii. Based on these results, the more active chloroform extract of C. peltata and ethyl acetate extract of P. gymnospora were further analyzed for their constit...

Alkaline hydrolysis of ethyl acetate is essentially an irreversible and second order reaction. Industrial importance of the reaction product, sodium acetate, necessitate for process improvement in terms of maximum conversion and economical usage of raw materials. Statistical design of experiments was utilized to enhance conversion in both batch and plug flow reactors.A full two level factor...
