• 説明

  D-(+)-Raffinose is a trisaccharide composed of galactose, glucose, and fructose that occurs naturally in a variety of vegetables and grains. It is hydrolyzed to galactose and sucrose by α-galactosidase.

• 使用

  D-(+)-Raffinose is a trisaccharide built from 1 mol each of D-galactose, D-glucose, and D-fructose which are obtained from it by acid hydrolysis. Invertase splits it into melibiose and saccharose. D- (+)-Raffinose occurs in Australian manna; in cottonseed meal.

• 調製方法

  Raffinose occurs naturally in Australian manna, cottonseed meal, and seeds of various food legumes. It can be isolated from beet sugar molasses through sucrose separation, seed-crystallization, and filtration.

• 応用例（製薬）

  Raffinose is a trisaccharide carbohydrate that is used as a bulking agent, blood substitute, stabilizing agent, and water scavenger in freeze-drying where it acts as a stabilizer for freeze-dried formulations. It is also used as a crystallization inhibitor in sucrose solutions.

• 安全性

  Raffinose is a naturally occurring trisaccharide investigated for use in freeze-dried pharmaceutical formulations. It occurs in a number of plants that are consumed widely.

• 貯蔵

  Raffinose is stable under ordinary conditions of use and storage. Excessive heat should be avoided to prevent degradation. Thermal decomposition products are carbon monoxide and carbon dioxide.

• 純化方法

  fructo-furanose [17629-30-0 (5H2O), 512-69-6 (anhydrous)] M 594.5, m 8 0o, 80 -82o, +124o (c 10, H2O), [ ] D +105o (c 1 for pentahydrate, H2O), pK 1 12.40, pK 2 13.44, pK 3 13.52. 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).

• 不和合性

  Raffinose is incompatible with strong oxidizers.

• 規制状況(Regulatory Status)

  Raffinose is a naturally occurring trisaccharide and is consumed as part of a normal diet.
