Determination of Eight Metal Elements in Cichorium glandulosum Boisset Huetby Microwave Digestion-FAAS
The Cichorium glandulosum Boiss et Huet is a traditional Uighur natural herbal medicine, but has not been analyzed and studied in terms of its metalel ements. In the experiment, the Cichorium glandulosum Boiss et Huet powder was digested with HNO3 by microwave digestion before determination.The eightmet alelements, potassium, nickel, calcium, magnesium, iron, manganese, copper and zinc, in Cichorium glandulosum Boiss et Huet were determined by FAAS. The working conditions, accuracy and precision of themethod were studied. The linear correlations of standard curves are good(r=0.9991-0.9999). The recovery(n=6) is 92.25%-110.5%, and the RSD (n=6) is 0.7%-3.88%. The results showed that there were comparatively rich metal elements, among which are comparatively highcal cium (65.84mg·g-1), iron(24.38mg·g-1), magnesium (278.17mg·g-1)and potassium (18.50mg·g-1), in Cichorium glandulosum Boiss et Huet, and the contents of other elements are nickel of 0.00438mg·g-1, manganese of 0.52mg·g-1, copperof0.0165mg·g-1 and zinc of 0.18mg·g-1. This provided useful data for discussing the relationship between the content of the metalel ements in Cichorium glandulosum Boiss et Huet and its clinical application in cardiovascular and osteoporosis disease.
