Chemical composition and bioactivities of a water-soluble polysaccharide from the endodermis of shaddock

“…Total sugar content was determined by the phenol-sulfuric acid analysis using d-glucose as standard [13]. The protein contents in EPS were measured was analyzed by the method of Bradford using BSA as the standard [14].…”

Efficient method for the screening and identification of anti-diabetic components in the leaves of Olea europaea L.

“…13 Thus, the inhibition of a-amylase activity is considered to be an effective strategy to control diabetes, because the inhibitors of a-amylase are effective in delaying glucose absorption by breaking down long-chain carbohydrates. From this point of view, more researchers have focused on the search for more effective inhibitors of a-amylase from natural materials to use as anti-diabetic treatments, 14,15 such as polysaccharides from tea leaves, 16 hydrolysate from sardine muscle and isoflavones from soybeans. 17 It is time-consuming and difficult to screen natural hypoglycemic agents in complex mixtures.…”

Comparison of anti-diabetic effects of polysaccharides from corn silk on normal and hyperglycemia rats

“…Among the diabetic cases, Type 2 diabetes accounts for more than 90%. Diabetes is one of the most challenging diseases for health care professionals today, and its increasing prevalence has put a large burden on society and the public health sector [1,2]. It is reported that about 800 plants may possess anti-diabetic potential [1].…”
