摘要：

Besides characterisation of desglucoanagalloside, anagallisins A, B, D and E, four new triterpenoid oligoglycosides isolated from the aerial part of Anagallis arvensis were respectively defined to be anagalligenin B 3-0-{beta-D-xylopyra-nosyl (1 --> 2) -beta-D-glucopyranosyl (1 --> 4) - [beta-D-glucopyranosyl-(1 --> 4) -beta-D-glucopyranosyl (1 --> 2)]-alpha-L-arabinopyranoside} (1), anagalligenone 3-0-{beta-D-xylopyranosyl (1 --> 2)-beta-D-glucopyranosyl (1 --> 4)-[beta-D-glucopyranosyl (1 --> 4) -beta-D-glucopyranosyl (1 --> 2)]-alpha-L-arabinopyranoside} (2), anagalligenone 3-0-{beta-D-xylopyranosyl (1 --> 2)-beta-D-glucopyranosyl (1 --> 4)-[beta-D-glucopyranosyl-(1 --> 2)]-alpha-L-arabinopyranoside} (4) and anagalligenin B-3-O-{beta-D-glucopyranosyl (1 --> 2)-[beta-D-glucopyranosyl (1 --> 4)]-alpha-L-arabinopyranoside} (5). The structural features were elucidated by a combination of fast - atom - bomardment mass spectrometry, strategic chemical degradation, and H-1 and C-13 NMR spectroscopy.
