Comparative analysis of over-the-counter tablet preparations of isoflavones extracted from soy available in Portugal

abstract

The results of a survey of 28 over-the-counter tablet preparations of isoflavones extracted from soy and 2 with black cohosh that are available in Portuguese pharmacies are presented. All were remedies for hot flushes and post-menopause related problems. Their isoflavone content was analysed by HPLC/DAD and LC/MS-MS. The results show that the isoflavonoids in soy extracts sold by the pharmaceutical companies in Portugal are mainly daidzin, glycitin and genistin.
