Abstract：The contents of 8 kinds of active ingredients ( 6 kinds of chlorogenic acids and 2 kinds of fla-vonoids ) in the leaves of Lonicera japonica Thunb .from different regions were simultaneously determinated by HPLC method and made significance analysis using SPSS software .Then the grey correlation degrees between the contents of active ingredients and climate factors were analyzed by GTMS 3 .0 system software .The results showed that the active ingredient contents in the leaves of Lonicera japonica Thunb .from different regions were significantly different .The quality of Lonicera japonica Thunb .from Shandong was the best , followed by Hebei and Henan .The sunshine duration , rainfall and relative humidity were the main climate factors affecting the active ingredient contents in leaves of Lonicera japonica Thunb..
