摘要： The objective of this study was to investigate how parts and maturity of Brasenia schreberi could affect its chemical composition and bioactivities. Among different parts of B. schreberi, G-BS sample contained the highest total carbohydrate content (589.1 +/- 11.07 mg/g) and total polyphenols content (mg GA/g), while it had relatively low HO center dot (IC50 = 3.42 +/- 0.12 mg/ml), DPPH (IC50 = 4.39 +/- 0.24 mg/ml) and ABTS free radical (IC50 = 1.66 +/- 0.05 mg/ml) scavenging activity. Principal components analysis showed that mucilage covered B. schreberi was significantly different from the plant itself. Galactose (61.56 +/- 3.29 mg/g), fucose (36.45 +/- 0.68 mg/g), and arabinose (27.08 +/- 0.27 mg/g) were three top abundant monosaccharides in G-BS sample. G-BS contained about 57% of polysaccharides and it showed potential hypoglycemic activities as it exhibited comparable alpha-amylase (IC50 = 3.35 mg/ml) and alpha-glucosidase (IC50 = 1.94 mg/ml) inhibitory activity to acarbose. G-BS might be a good source of polysaccharide that can be used as functional supplement. Practical applications As parts and maturity can affect chemical composition and bioactivity, present results help guide potential application of B. schreberi. The study will help food industry to develop B. schreberi polysaccharide-based products as a functional additive or pharmaceutical supplement.
