Abstract
A method for the GLC determination of methyl salicylate, safrole, and related compounds in nonalcoholic beverages was studied collaboratively and reported previously. Only the methyl salicylate analysis gave acceptable precision and accuracy at all spiking levels. The study was continued and the optimum conditions for the analysis of safrole were selected. The present collaborative results show that average recoveries for safrole ranged from 77 to 98% with more variable recoveries obtained for isosafrole, dihydrosafrole, and dihydroanethole. The method has been adopted as official first action for the quantitative determination of safrole and for the semiquantitative determination of the 3 related components in nonalcoholic beverages.
