Abstract
A high molecular weight fructan was isolated from garlic and the structure determined by enzymatic, chemical and spectroscopic (NMR) methods. It was f ound that the garlic fructan belongs to the neokestose family. It has a (2 --> 1)-linked beta-D-Fruf backbone with (2 --> 6)-linked beta-D-Fruf side c hains. A structural model was postulated for a degree of polymerisation of about 58. This model was substantiated using an endo-inulinase purified fro m Aspergillus ficuum and by H-1 and C-13 NMR spectroscopy. (C) 2000 Elsevie r Science Ltd. All rights reserved.
