The purpose of this study was to determine, through beta-carotene analysis, the provitamin A value of three vegetables leaves ("serralha", celery and mint), raw and submitted to two ways of cooking: boiling and microwave. Samples of "serralha" presented the better provitamin A value beyond the three leaves analyzed: 1, 373 RE/100g for raw samples. Except for mint, it was observed a significant lost of provitamin A due the two ways of cooking.
