Pachymaran Hydroxypropylation and Applied Research
Abstract: Hydroxypropylation Pachymaran was obtained by the method of propylene oxide under alkaline conditions . The degree of substitution was obtained from elemental analysis, which was 0.33,and the Solubility Viscosity of Hydroxypropylation parchymaran. In addition, the Hydroxypropyl groups in the parchymaran derivative was investigated by FT-IR analysis。The physiological properties of Hydroxypropylation parchymaran were characterized。Hydroxyl radical capacity of Hydroxypropylation parchymaran was examined by the method of Feton reaction,showing the effects of hydroxyl radical scavenging rate to strengthen. Moreover, the Hydroxypropylation parchymaran showed higher bile acid binding activity than native glucan.
Key words: pachymaran; Hydroxypropylation; FT-IR; bile acid binding; Viscosity
