Abstract:
AIM:To screen and verify the effective ingredient of traditional Chines medicine (TCM) Q0409 in improving learning and memory ability of mice.METHODS:The mouse learning and memory impairment model was induced by intraperitoneal injection of scopolamine.The mice in each group were given the corresponding drug by gavage at the same time for 14 d in succession.Morris water maze test was used to measure the learning and memory ability of the mice, and then the hippocampal tissue homogenate was taken to determine the activity of acetylcholinesterase (AChE).The animals were divided into 8 groups according to L8(27) orthogonal table.The variance analysis and factorial analysis were used to analyze the pharmacological effects of seven kinds of single herbal in TCM Q0409 and determine the screening ingredients.The animals were divided into 6 groups according to the results of the preliminary screening results, and further testing and validation of TCM Q0409 screening ingredients were performed to get the final simplified ingredients.RESULTS:Three medicinal herbs of Polygalae, Panax ginseng and Acori graminei rhizome were screened by the orthogonal results of Morris water maze test and the activity of AChE in mouse hippocampal tissues.The simplified ingredients of TCM Q0409 were obtained through the variance results of Morris water maze test and the activity of AChE in mouse hippocampal tissues.CONCLUSION:Polygala and ginseng were eventually determined as simplified ingredients of TCM Q0409 and it was verified that they improve the learning and memory ability of the mice with learning and memory impairment.
