【Abstract】 Objective:To study the influence of temperature and alcohol concentration on extraction efficiency on extraction anthraquinone glycoside from polygonum cuspidate. Methods: Anthhraquinone glycoside is extracted from polygonum cuspidate by using the methods that Polygonum cuspidatum was extracted by alcohol, then was adsorbed by polyamide and finally was desorbed by alcohol. Results: It was shown that extraction efficiency increased while temperature rosd. It also showed that extraction effciency increased while the alcohol concentration increased. Conclusion: To increase temperature and alcohol concentration is favorable to improve extraction efficiency.更多还原
