Abstract
Extensive chromatographic separation of the n-BuOH soluble fraction obtained from the stem and root barks of U. davidiana resulted in five hitherto unknown compounds together with a known one (-)-catechin 1. Structures of the five compounds were elucidated by chemical and spectroscopic analyses, to be (-)-catechin-7-O-gallate-5-O-(5aEuro(3)aEuro(3)-trans-caffeoyl)-beta-d-apiofuranoside-3-O-beta-d-apiofuranosyl-(1 -> 2)-beta-d-glucopyranoside 2, (-)-catechin-7-O-gallate-5-O-(5aEuro(3)aEuro(3)-trans-caffeoyl)-beta-d-apiofuranoside-3-O-beta-d-glucopyranoside 3, (-)-catechin-7-O-gallate-5-O-beta-d-apiofuranoside-3-O-(2aEuro(3)-O-galloyl)-beta-d-glucopyranoside 4, (-)-catechin-7-O-gallate-5-O-(5aEuro(3)aEuro(3)-trans-caffeoyl)-beta-d-apiofuranoside 5, and (-)-catechin-7-O-gallate-5-O-(5aEuro(3)aEuro(3)-trans-feruloyl)-beta-d-apiofuranoside 6.
