| Abstract: | The system of n-C8H17OH-H2O was adopted to study the distribution of magnesium in the extract of Wolferry Fruit,Safflower and Chrysanthemum Flower.The magnesium contents,the magnesium solubility of Decoction and the solubility under gastric and intestinal acidity in Wolferry Fruit,Safflower and Chrysanthemum Flower were determined by flame atomic absorption spectrometry（FAAS）.The result showed that the effect of gastric and intestinal acidity as well as compatibility on dissolved state of magnesium was significant.The recovery was 98%-102%,and RSD is 0.60%-2.99%. |
| Keywords: | FAAS Chinese herbal medicine magnesium solubility |
