To investigate the effects of caffeic acid ester fraction (Caf) from Erigeron breviscapus, mainly composed of dicaffeoylquinic acids (diCQAs), on microglial activation in vitro and focal cerebral ischemia in vivo. The production of nitric oxide (NO), tumor necrosis factor α
Five new quinic acid derivatives and two known 3-O-feruloylquinic acids were isolated from the roots of Scorzonera divaricata Turcz. The new compounds were elucidated as (-)-1,4-di-O-feruloyl-3-O-dihydrocaffeoylquinic acid, (-)-1-O-feruloyl-4-O- dihydrocaffeoylquinic acid, (-)-3,5-di-O-feruloylquinic acid, (-)-1-O-feruloyl-3-O-dihydro- caffeoylquinic acid, and (-)-1-O-feruloyl-5-O-dihydrocaffeoylquinic acid based on
