In addition, antioxidant activities of related polysaccharides were also evaluated. The results showed that the molecular weight of GBP11, GBP22, and GBP33 were 1.944 × 103 KDa, 5.167 × 103 KDa, and 45.98 KDa, singly, and they were mainly made up of glucose, galactose, arabinose, and rhamnose with a molar ratio of 62.2:1.98:3.84:1.24, 3.57:68.0:4.67:0.36 and 5.34:48.8:1.70:8.97, respectively. Moreover, GBP22, GBP, and GBP11 demonstrated the strongest free radical scavenging activity on DPPH, ABTS, and superoxide anion, showing that they have potential application value on the functional food and cosmetic industry. Practical applications Enzymatic hydrolysate of Ginkgo biloba leaves includes lots of carbohydrate, it will cause eutrophication and environment pollution if it is directly poured out. This research indicates that carbohydrate extracted from enzymatic hydrolysate of Ginkgo biloba leaves are made up of different polysaccharide monomers with various molecular weight and monosaccharide composition. Moreover, these polysaccharide monomers possess appreciating antioxidant activities. Therefore, this research could lay a foundation for the high-value application of polysaccharides in functional food and cosmetic industry, and provide theoretical reference for the treatment of waste water.
