title: Galloyl and hexahydroxydiphenoyl esters of phenylpropanoid glucosides, phenylpropanoids and phenylpropanoid glucosides from rhizome of Balanophora fungosa.
abstract: Five new galloyl and (S)-hexahydroxydiphenyl (HHDP) esters of phenylpropanoid glucosides; 1-O-(E)-coumaroyl-3-galloyl-4,6-(S)-HHDP-beta-D-glucopyranose (21), 1-O-(E)-coumaroyl-3,4,6-trigalloyl-beta-D-glucopyranose (22), 1-O-(E)-caffeoyl-3,4,6-trigalloyl-beta-D-glucopyranose (23), 1-O-(E)-cinnamoyl-3-galloyl-4,6-(S)-HHDP-beta-D-glucopyranose (24), and 1-O-(E)-cinnamoyl-4-galloyl-beta-D-glucopyranose (25), together with twenty known compounds which were identified as four triterpenes (1, 2, 3, 5), one steroid (4), one lignan (6), three phenylpropanoids (7, 8, 14), five phenylpropanoid glucosides (10, 12, 13, 15, 16), five galloyl and HHDP esters of phenylpropanoid glucosides (11, 17-20), and one bischroman (9). Their structures were determined on the basis of 1D and 2D spectroscopic data.
