Objective: To study the correlation of plasma concentration before and after ultrafine grinding and Corydalis Decumbentis Rhizoma bioavailability by oral administration in mice. Method: Acetic acid induced writhing response was used to observe analgesic effect in mice and the blood contained in the amount of alkaloids. Result: By ultrafine grinding of Corydalis Decumbentis Rhizoma
stronger inhibitory effect on acetic acid induced writhing response was fund compared with the ordinary pieces
alkaloid content in the blood was higher than ordinary pieces. Conclusion: Ultrafine grinding can improve the bioavailability of Corydalis Decumbentis Rhizoma.
