摘要: Two derivatives of shikimic acid were isolated from croziers of the dwarf tree fern, Dicksonia antarctica, and their structures were elucidated as 4-O-caffeoylshikimic acid and 4-O-(p-coumaroyl)-shikimic acid on the basis of mass spectrometric and NMR spectroscopic evidence....
Experiments prove that coumaroyl quinic acid and coumaroyl shikimic acid can be respectively catalyzed into chlorogenic acid and caffeoyl shikimic acid by adding an LjC3'H protein purified in vitro into an enzymatic reaction system, so that a theoretical foundation and a practical basis for developing...
