Abstract:
OBJECTIVE: To optimize the ethanol extract technology of Liaojin membranes. METHODS: Alcohol extract rate and Emodin content were taken as the indexes for investigation and orthogonal test was carried out to investigate the effects of three extracting factors (alcohol density, alcohol amount and extracting time) on the extract technology. RESULTS: The optimum extract technology was A2B2C2, i.e. adding 70% alcohol which was 6 times the quantity of medicine and extracting twice (1.5h the first time and 1h the second time). CONCLUSION: The optimized ethanol extracttechnology for Liaojin membranes is simple, rapid and accurate, and serves as theoretic basis for the industrialized production of this preparation.
