Mucilage of malva nut fruit has been used as traditional medicine in Thailand. Our laboratory has succeeded in extracting malva nut gum (MNG) from malva nut seeds by using alkaline-extraction method. The extract had higher gelling properties compared to water-extracted MNG. This research was aimed to investigate the effect of MNG on the retardation of glucose diffusion in in vitro dialysis processes. The results showed that alkaline-extracted MNG significantly (p<0.05) reduced glucose content in dialysate compared to control containing no dietary fibre. MNG at 1% (w/w) concentration was more effective than that of 0.5% (w/w) concentration. The mixture of MNG and guar gum significantly (p<0.05) reduced glucose in dialysate by 50-82% compared to that of control. In starch digestion process, the mixture of MNG and guar gum showed greater reduction of glucose (3-7 folds) in dialysate at 15-30min.
锦葵果黏液在泰国被用作传统药物。我们的实验室已经成功地从锦葵果种子中用碱性提取法提取出锦葵果胶（MNG）。与水提 MNG 相比，提取物具有更高的胶凝性能。本研究旨在探讨 MNG 对体外透析过程中葡萄糖扩散延迟的影响。结果表明，与不含膳食纤维的对照相比，碱性提取的 MNG 显著（p<0.05）降低了透析液中的葡萄糖含量。1%（w/w）浓度的 MNG 比 0.5%（w/w）浓度的 MNG 更有效。MNG 与瓜尔胶的混合物与对照相比，显著（p<0.05）降低了 50-82%的透析液中葡萄糖含量。在淀粉消化过程中，MNG 与瓜尔胶的混合物在 15-30min 时使透析液中的葡萄糖（3-7 倍）减少。
