The fragmentation behavior of all six dicaffeoylquinic acids (diCQA) has been investigated using LC-MS4. It is possible to discriminate between each of the isomers including those for which commercial standards are not available. For diCQA, the

Efficient synthesis of 1-, 4-, and 5-caffeoylquinic acid was achieved in three or four steps with suitably protected quinic acid precursors, in overall yields of 41%, 36%, and 60% [from quinic acid (1)]. 1-Caffeoylquinic acid was prepared by esterificatio
