the alkyl lead and alkyl lead salts, and then extracted with dilute nitric acid The pH of the aqueous extract is adjusted by means of a buffer and the lead is extracted with a chloroform solution of dithizone The absorbance of the chloroform extract is measured and the lead content is determined from a previously prepared calibration curve
dichloromethane and ethyl acetate before extraction with a 10 acetic acid/ethyl acetate solution The solvent was evaporated, and the residue was washed with dichloromethane then dried to provide shikimic acid as an off-white solid (2 21 g, 5 5 w/w) that was sufficiently pure, as judged by 1H and 13C NMR (Scheme 1)
acid content was expressed in terms of mass fraction of to obtain the dichloromethane extract of pyroligneous acid (DCPAP) The organic solvent extract was prepared for experimen-tal
of linoleic acid (C18:2n6) in the dichloromethane extract, which instead contained the highest amount (greater than 60 ) of oleic acid (C18:1n9) Polyphenolic compounds with pharmacological
ascorbic acid was used to prepare a standard solution (1mg/mL) The ascorbic acid concentration was calculated by comparison with the standard and expressed as mg/ 100g fresh mass Total phenolics content was determined by the Folin– Ciocalteu method, which was adapted from Swain and Hillis (1959) The 150mL of extract, 2400mL of nanopure
