Method for determining chlorogenic acid, caffeic acid and 4-methoxysalicylaldehyde contents in streptocaulon griffithii hook by using QAMS method

The invention belongs to the chemical technology field and especially relates to a method for determining chlorogenic acid, caffeic acid and 4-methoxysalicylaldehyde contents in streptocaulon griffithii hook by using a QAMS method. The determination method adopts an HPLC method, and the chlorogenic acid is taken as an internal reference substance so as to establish a relative correction factor with the caffeic acid and the 4-methoxysalicylaldehyde. The relative correction factor is used to calculate the contents of the caffeic acid and the 4-methoxysalicylaldehyde in the streptocaulon griffithii hook. The determination method uses only one reference substance to achieve simultaneous measurement of multiple components, detection cost of buying the reference substance with a high price is reduced, and simultaneously, quality of traditional Chinese medicine is simply and comprehensively controlled, and work efficiency of simultaneous measurement of multiple components is improved. 本发明属于化学技术领域，具体涉及一种采用一测多评法测定古羊藤中
