摘要：

A useful method for the determination of ascorbic acid in a vegetable product (asparagus) by differential pulse polarography has been set up and evaluated. Extraction and instrumental conditions were optimized. The analytical parameters are: linearity (0-18.18 mu g/ml); detection limit (0.182 mu g/ml); instrumental and method precision (2.77% and 4%, respectively); accuracy (96.9-113.4%). These data show that the method is sufficiently sensitive, reliable and accurate, It was also compared with the official fluorometric AOAC method.
