Abstract : haride was extracted from L yci um ret henicum Murr and t he content was deter
mined. Ultrasonic microwave synergistic extraction technique applied in haride of L yci um re
t henicum Murr were obtained , content determination with ant hrone sulp huric acid colorimetry. Re
sult s showed content of haride was 10. 89 % , recovery rate is 100. 07 % , RSD = 1. 89 % ( n =
3) . The met hod was simple , rapid and accurate.
