Abstract

Fruiting body of Tremella aurantialba cultivated in Lanzhou was used for experimental material.Tremella aurantialba pure polysaccharide (TAPP), an acidic heteropolysaccharide, was obtained from the material, with uniform molecular weight distribution (Mw=1.54×106 Da).Monosaccharide composition indicated that TAPP was composed of Man, GlcA, Glc, and Xyl with the ratio of 55.20∶9.76∶14.81∶20.23, and included a little Gal and GalA.The experiences of Fourier transform infrared spectroscopy, Congo red, scanning electron microscope, and thermogravimetric analysis showed that TAPP contained β-glycosidic bonds and helical structure, surface micromorphology presented lamellar and irregular aggregation, and it had good chemical stability below 170 ℃.The activity analysis showed that the inhibition of TAPP on α-amylase and α-glucosidase was positively correlated with concentration.The inhibitory effect on α-glucosidase was more significant, and the inhibition rate reached (93.32±1.09)% at TAPP concentration of 2.0 mg/mL.Its inhibition rate was similar to the effect of acarbose (P<0.05).It could significantly improve the insulin resistance of HepG2-IR model cells induced by palmitic acid when the concentration of TAPP reached 75 μg/mL (P<0.05).The results of this study provide theoretical supports and basis for further development and utilization of Tremella aurantialba resources in Lanzhou.
