Abstract
Four new estersaponins were isolated from Hacquetia epipactis. Using G C-MS, FAB-MS and various 2D-NMR techniques they were identified as 3-O -{beta-D-glucopyranosyl-(1 --> 2)-[alpha-L-arabinopyranosyl-(1 --> 3)] -beta-D-glucuronopyranosyl-(1 ->)}-21-acetyl-22-(2-methylbutyryl)-barr ingtogenol C (hacquetiasaponin 1), the corresponding 1-(2-acetoxy-2-me thylbutyryl)-22-acetyl-derivative (hacquetiasaponin 2), 3-O-{beta-D-gl ucopyranosyl-(1 --> 2)-[alpha-L-arabinopyranosyl-(1 --> 3)]-beta-D-glu curonopyranosyl-(1 >)}-21-acetyl-22-(2-methylbutyryl)-R(1)-barrigenol (hacquetiasaponin 3) and its corresponding 1-(2-acetoxy-2-methylbutyry l)-22-acetyl-derivative (hacquetiasaponin 4).
