Abstract:
A method for extraction of tectoridin and tectorigenin from the rhizomes of Belamcanda chinensis is provided to reduce the extraction time, improve the extraction yield and enhance environment and human affinity by using only water and ethanol as solvent under high temperature and high pressure. The tectoridin and tectorigenin are extracted from the rhizomes of Belamcanda chinensis through SWE(subcritical water extraction) by heating the rhizomes of Belamcanda chinensis in a mixed solvent containing water and 30-100 vol.% of ethanol to high temperature such as 80 deg. C or more, preferably 80-200 deg. C under high pressure condition such as 1-15 MPa.
