Gilck, H; Thanbichler, A; Sellmair, J; Beck, E: A simple method for the isolation of Crystalline D-Hamamelose, Carbohydr. Res., 39, 160-161 (1975), doi:10.1016/S0008-6215(00)82651-8
Abstract:
Isolation of n-hamamelose from the bark of witch-hazel (Hamamelis z.Grginiana L.) according to the procedure of Freudenberg and Bluemmel’ gives a syrupy product. Crystalline D-hamamelose has been prepared by chemical synthesis2; however, for large-scale preparations, the procedure is rather complicated. We now report a simple method for the isolation of crystalline D-hamamelose in good yield from the bark of witch-hazel
