Construction method and detection method for atalantia buxjfolia medicinal material finger-print

The invention relates to a construction method and a detection method for an atalantia buxjfolia medicinal material finger-print. The construction method comprises the following steps: precisely weighing atalantia buxjfolia medicinal material powder, precisely adding methanol, carrying out reflux extraction or ultrasonic extraction for 45-60 minutes, and filtering to obtain a test solution; and precisely sucking the test solution, injecting the test solution into a high performance liquid chromatograph and testing the test solution to obtain the atalantia buxjfolia medicinal material finger-print consisting of 18 characteristic peaks. The atalantia buxjfolia medicinal material finger-print has 18 characteristic peaks capable of relatively comprehensively representing the physical and chemical characteristics of the atalantia buxjfolia medicinal material, so that the atalantia buxjfolia medicinal material can be accurately and intuitively identified, and moreover, the method has the advantages of being simple to operate, stable in result, high in precision, good in reproducibility and the like.
