D(+)-Raffinose pentahydrate C화학적 특성, 용도, 생산

개요

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.

용도

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.

생산 방법

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.

Pharmaceutical Applications

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.

Safety

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.

저장

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.

Purification Methods

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).

비 호환성

Raffinose is incompatible with strong oxidizers.

Regulatory Status

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