TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The step (i) comprises: using the alkaline water as aqueous solution of sodium hydroxide or potassium hydroxide (5%); during removing the impurities, the liquid-solid ratio of the added amount (ml) of the alkaline water to the mass (g) of the glossy privet leaves or glossy privet fruit is 6-8 times, and the boiling time is controlled to 20-30 minutes; during aqueous extraction of solution, the liquid-solid ratio of the added amount (ml) of the pure water to the mass (g) of the glossy privet leaves or glossy privet fruit is 8-12 times, and the extracting time in the boiling water bath is 1-2 hours; during alcohol extraction of the solution, the concentration of the ethanol solution is more than 80%, the liquid-solid ratio of the added amount (ml) to the mass (g) of the glossy privet leaves or glossy privet fruits is 10-15 times, and the extracting 2-3 times for 1.5-2 hours. The step (ii) comprises: using the reagent for adjusting the alkalinity as aqueous solution of sodium hydroxide or potassium hydroxide (1 mol/l), where the pH value is controlled within 9-11; using the reagent for adjusting the acidity as aqueous solution of hydrochloric acid (6 mol/l), where the pH value is controlled within 3-4; and taking the decompressed and concentrated volume of the filtrate as 1/3-1/4 of the volume of the filtrate before being concentrated. The step (iii) comprise: using the reagent for adjusting the alkalinity as aqueous solution of sodium hydroxide or potassium hydroxide (10%), where the pH value is controlled within 11; using the reagent for adjusting the acidity as aqueous solution of hydrochloric acid (6 mol/l), where the pH value is controlled to be 1; and using the boiled alkaline water as aqueous solution of sodium hydroxide or potassium hydroxide (5%), where the boiling time is controlled within 15-30 minutes, and the liquid-solid ratio of the added amount (ml) to the precipitate (g) is 6-8 times. The method comprises decoloring ethanol extract solution by adding the activated carbon with liquid-solid ratio of 0.1-1.0% at 50-60 degrees C, stirring to absorb for 15-60 minutes, and repeating the step for 2-3 times.
