Abstract
Six novel fucose 3-O-acetylated saponins, with a quillaic acid aglycone, were isolated from a bark extract from the Quillaja saponaria Molina tree. In addition, a saponin with a novel aglycone (phytolaccagenic acid) and a novel fatty acyl group [(S)-2-methylbutanoyl] for Quillaja saponins was found. The compounds were characterised using NMR spectroscopy, mass spectrometry and chemical methods.
