Purification Effect of PES-C Ultrafiltration Membrane Incorporated with Emodin on Acanthopanax Senticosus Injection

Abstract

A new PES-C/emodin ultrafiltration membrane was prepared by blending natural emodin with phenolphthalein polyethersulfone (PES-C) and was used to purify an acanthopanax senticosus injection in this study. Regarding the purified acanthopanax senticosus injection, its color became lighter, and its clarity increased. On the contrary, for an acanthopanax senticosus injection containing macromolecules, its color deepened, and its turbidity increased. Thermal stability of the purified acanthopanax senticosus injection was the best, followed by the original solution of the acanthopanax senticosus injection, and the acanthopanax senticosus injection containing macromolecules was the worst. The fingerprint spectrum of the purified acanthopanax senticosus injection was similar to the original solution of the acanthopanax senticosus injection, the relative peak area of each single peak was greater than 0.95, and the relative peak area of the total peak was greater than 0.96. Compared with the original solution of the acanthopanax senticosus injection, the histamine release amount and cell degranulation rate of the acanthopanax senticosus injection containing macromolecules increased, while those of the purified acanthopanax senticosus injection decreased, which reduced the risk of allergic reaction to a certain extent. “Inverse proof” confirmed that the acanthopanax senticosus injection containing macromolecules had certain liver and kidney toxicity, which indirectly proved that the liver and kidney toxicity of the purified acanthopanax senticosus injection was effectively reduced.
