Five new sucrose esters from the whole plants of Phyllanthus cochinchinensis

Chemical investigation of the whole plants of Phyllanthus cochinchinensis (Euphorbiaceae) led to the isolation of five new sucrose benzoyl esters, 3,6′-di-O-benzoylsucrose (1), 3,6′-di-O-benzoyl-2′-O-acetylsucrose (2), 3,6′-di-O-benzoyl-4′-Oacetylsucrose (3), 3,6′-di-O-benzoyl-3′-O-acetylsucrose (4) and 3-O-benzoyl-6′-O-(E)-cinnamoylsucrose (5), together with two known secoiridoid glycosides, jasminoside (6) and jaslanceoside B (7). Their structures were established on the basis of detailed spectroscopic analysis and chemical method.
