2.6.3. Adsorption of Dencichine on Different Mass RCMs and RPMs

The RPMs (10, 15, 20, 25, 30, 35, 40 mg) were weighed with an analytical balance and placed into round 50 mL conical flasks. After adding 20 mL of dencichine solution, it was adsorbed for 5 h in an 80 rpm air constant temperature oscillator at 25 ◦C. The RCMs (75, 100, 125, 150, 175 mg) were weighed with an analytical balance. After adding 20 mL of dencichine solution, it was adsorbed for 5 h in an 80 rpm air constant temperature oscillator at 25 ◦C. The content of dencichine after adsorption was determined by HPLC. The dencichine adsorption amount of RCMs and RPMs was calculated based on Equation (4).
