D(+)-Raffinose crystallises from H2O, 90% aqueous EtOH or MeOH as the pentahydrate. The anhydrous sugar has m 132-135o. It has RF 0.8 on TLC (Silica Gel, and 1:3:3 CHCl3/butanone:/MeOH). The undecaacetate has been purified through an alumina column by elution with CHCl3, and recrystallised from EtOH/MeOH/H2O (3:2:5), with m 99-100o, [] D +92.8o (c 5.14, EtOH).
