Anti-hyperglycemic effect of the polysaccharide fraction isolated from mactra veneriformis

Lingchong WANG, Hao WU, Nian CHANG, Kun ZHANG

《化学科学与工程前沿（英文）》 2011年第5卷第2期页码 238-244 doi: 10.1007/s11705-010-0002-2

摘要： Total macromolecule extract was obtained from the soft body of by the coupling techniques of decoction and alcohol precipitation. The extract was deproteinized with an ion exchange column, and resulted in the purifying of the crude polysaccharide fraction. It was found by chemical analysis that the crude polysaccharide part is composed of abundant polysaccharides (>95%) and few proteins (<1%). Furthermore, only one type of monosaccharide, glucose, was detected from its hydrolytes by thin-layer chromatography, indicating that the polysaccharides might be analogs of glucosan. The anti-hyperglycemia effects of the crude polysaccharide part were preliminarily investigated using several pharmacological methods in normal and diabetic mice. Animal experimental results showed that the crude polysaccharide fraction exhibited proper glycemia inhibition activity, and 300 mg/kg-weight dose has the optimal effect among all the studied doses. It is concluded that the crude polysaccharide fraction can be explored as a novel health product that possesses potential as an anti-hyperglycemic agent.

摘要：

胆固醇和葡萄糖稳态异常在心血管疾病、脑血管疾病、中枢神经系统疾病和癌症等多种疾病的发生发展中起着至关重要的作用。越来越多的研究表明，体内脂肪堆积过多与2型糖尿病或胰岛素抵抗有关，高胆固醇和高血糖将加重上述疾病的发展进程。因此，稳定患者的血脂和血糖水平是改善心脑血管和中枢神经系统疾病患者症状的主要策略。中药（CHM）在中国已有两千多年的历史，建立了独特的中医理论，积累了丰富的临床经验。此外，中药在国内外广泛应用于心脑血管疾病的治疗和预防，具有防治高脂血症、糖尿病和高血压等疾病的优势。然而，中药在西方国家的使用仍然相当有限，部分原因是对其多种复杂成分的了解不完整，药理机制不确定。本文就中药生物活性成分及其制剂治疗高脂血症和高血糖症的作用、分子机制和临床研究进展进行综述和讨论。
