摘要：
The glycyrrhizin contents of 42 samples of liquorice-containing confectionery, health products and raw materials have been determined by a standard (AOAC) HPLC technique. Confectionery levels ranged between 0·26 and 7.9 mgg- 1, whilst contents in health products were 0.30-47. 1 mgg- 1, the highest values being measured for throat pearls. Six geographically diverse samples of liquorice root contained similar (22.2-32.3 mgg- 1) glycyrrhizin contents. Highest levels of glycyrrhizin were found in liquorice block (44-98 mgg- 1) and extract powder (79-113 mgg- 1). These analyses enable a mean daily intake of glycyrrhizin to be calculated for the UK. The figure (1 mg) is lower than those reported for the US and Belgium (3 and 5 mg, respectively). The significance of the levels of glycyrrhizin in UK confectionery, and the estimated daily exposure thereto, is discussed in the context of existing data on liquorice-induced toxicity. © 1990 Taylor & Francis Group, LLC.
