PURIFIED SALACIA PLANT EXTRACT AND METHOD FOR PRODUCING PURIFIED SALACIA PLANT EXTRACT

摘要

The present invention addresses the problem of providing: a purified Salacia plant extract in which the salacinol content of the extract is not reduced at the time of purification, the salacinol concentration of the extract is maintained, and bitterness and/or astringency are reduced; and a method for producing the purified Salacia plant extract. The present invention provides a purified Salacia plant extract in which each of the epicatechin content and the epigallocatechin content is less than 0.001 mass% with respect to the total amount of the purified Salacia plant extract. The present invention also provides a method for producing the purified Salacia plant extract including an extraction step in which a Salacia plant-containing raw material extract containing at least one of a Salacia plant, a Salacia plant extract, and a crushed product of a Salacia plant is made to flow through a column filled with a styrene-based synthetic resin.
