A Research on the Stability of Guangxi Baise Mango Leaf Extract
HPLC and UV spectrophotometry were used to determine the absorbance and concentration of mangiferin,and its tolerance to light,heat,and acid-base was systematically studied.The measurement result shows that the absorbance value of mangiferin fluctuates a little under high temperature and light conditions.In contrast,the content of mangiferin significantly decreases under acidic and alkaline solid conditions.The conclusion is that mangiferin can tolerate light and high temperatures,and strong acids and bases can quickly destroy its stability.
