CHEMCALCONSTITUENTS OF LONICERA MAGRANTHOIDES HAND. -MAZZ PART V. ISOLATION AND STRUCTURES OF MACRANTHOIN F AND G

    Abstract
  • Lonicera macranthoides Hand. -Mazz of Caprifoliaceae is the sources of Jinyinhua, which is a well known antipyretic and antidote in traditional Chinese medicine. Chemical studies led us to isolate 11 new compounds.Further purification of a bioactive fraction from the EtOAc soluble portion yielded two new compounds named macranthoin F and G,Their structures wereelucidated as methyl 3,4-O-dicaffeoylquinate(Ⅰ)and methyl 3,5-O-dicaffeoylquinate(Ⅱ).
