Study on Adsorption and Sustained Release of Eucommia ulmoides Oliv. Leaf Extracts on Activated Carbon

摘要

Background: Due to its excellent adsorption capability, activated carbon(AC) has also been employed as a drug carrier. However, applications of the AC carrier in traditional Chinese medicine (TCM) have been rare. We selected the Eucommia ulmoides leaf extract as the drug of choice and AC as its carrier, to investigate the adsorption and sustained release behavior of the Eucommia ulmoides leaf extract on the AC.
