This study was conducted to determine the variation of phenolic compounds in the leaf and stem of 131 accessions of Lycium chinesis Miller. The levels of total phenolic compounds in the leaf of L. chinesis ranged between 8.8 to 14.9 mg g-¹ and among them 60% of the accessions belong between 11.6 and 13.5 mg g-¹ for the content of phenolic compounds in the leaf. The accession CB03286-89 contained the highest total phenolic compounds among the accessions tested, which was 1.7-fold higher than that of the lowest content accession CBP03310-250. In the stem, the total phenolic compound of 131 accessions of L. chinesis ranged from 6.8 to 12.4 mg g-¹, showing slightly lower level than that in the leaf. The content of (+)catechin was highest in the leaf and stem of accession CB03286-89 and Japan No.1, respectively. Myricetin was detected in the leaf of seven accessions (i.e. Geumsan jaerae, Japan No.1, China collection No.1, CL32-13, CB04329-13, China collection No.12 and CB03286-89) and in the stem of five accessions (i.e., Japan No.1, China collection No.1, China collection No.12, CB03286-89 and 99797). Accessions had a great influence on the content of phenolic compounds. So, accessions-specific phenolic compound profiles might be helpful for commercial use or production of phenolic compounds in L. chinesis.
