Abstract

Pueraria Radix has known to contain several ingredients of medical action. However, the bitter taste of Pueraria Radix has been an obstacle to develope the products and improve the added value of Pueraria Radix. To moderate the bitter taste of extracts from Pueraria Radix, charcoal powder was used successfully as an adsorbent. The component of the bitter taste from Pueraria Radix was hydrophobic, which mostly eluted with 40-60% ethanol and estimated to be acidic. Puerarin, the essential medical ingredient remained after the adsorption and seemed not be affected by the adsorption to charcoal powder.
