Embodiment 1
[0016] Example 1: The influence of acidity on adsorption rate
[0017] Sample preparation
[0018] Precisely weigh 10g of the dried Guangdong Purple Pearl powder (passed through a 24-mesh sieve), place it in a 500ml round-bottomed flask, and extract twice with distilled water, each with 150ml of the corresponding solvent, the first extraction is 2 hours, the second Extract for 1.5 hours each time, filter with suction after each extraction, combine the filtrate and the lotion of the lotion residue, and appropriately concentrate them in a 50ml volumetric flask to obtain the Guangdong Zizhu extract.
[0019] The method for the determination of total flavonoids in the samples refers to the determination of the total flavonoids of Sophora japonica in the 2005 edition of the People’s Republic of China Pharmacopoeia.
[0020] In this embodiment, the pH values are respectively 2.0, 3.0, 4.0, and 5.0 for investigation. Measure 5ml each of the processed weak polar or non-polar macroporous ad...
Embodiment 2
[0023] Example 2 The influence of the amount of water used in washing and removing impurities on purity and yield
[0024] Measure 15ml of the processed non-polar or weakly polar macroporous adsorption resin, load it into a column, load 40ml of column solution (total flavonoids 7.8mg / ml), load the column at a flow rate of 1ml / min, repeat the adsorption once, and let stand for 24h Then, 0.5, 1, 2, 3, and 4 times the volume of the resin were used to rinse and remove impurities, and then eluted with 100 ml of 70% ethanol. The total flavonoid concentration of each part was measured separately, and the total flavonoid content and yield were calculated.
[0025]
[0026] Note: According to the existing technical content, if it is necessary to wash to colorless as mentioned in the references, it needs more than 4 times the resin volume to wash. From the data provided in this example, it can be seen that when the washing amount reaches 2-3 times the resin volume At that time, the impuritie...
Embodiment 3
[0027] Example 3 Comparison of adsorption rate between static adsorption and dynamic adsorption
[0028] Measure two portions of the processed weakly polar or non-polar macroporous adsorption resin, 5ml each, and add 25ml of Guangdong purple bead extract (total flavonoids 7.8mg / ml). One sample solution is statically adsorbed for more than 2 hours Method; another sample solution adopts dynamic adsorption method. After the adsorption is complete, the concentration of the unadsorbed sample solution is measured and the adsorption rate is calculated.
