Structure and antioxidant activity study of sulfated acetamido-polysaccharide from Radix Hedysari

Purification and characterization of a glucan from Bacillus Calmette Guerin and the antitumor activity of its sulfated derivative

“…In recent years, polysaccharides have aroused the interest of many researchers, owing to their broad spectrum of biological activities, such as immunomodulation, antitumor, antioxidation, hypoglycemic activity and so on (Dang et al, 2013;Wang et al, 2014;Sun, Wang & Zhou, 2012;Zhu et al, 2013). Much evidence has indicated that chemical modifications and structural improvements of polysaccharides can bring stronger or new biological activities.…”

Structural characterization of a polysaccharide from Chrysanthemum morifolium flowers and its antioxidant activity

“…4 and Fig. S1) and literature values (Dang et al, 2013;Li, Dobruchowska, Gerwig, Dijkhuizen, & Kamerling, 2013;Nie et al, 2011;Shang et al, 2012;Sun, Cui, Tang, & Gu, 2010;Xu, Dong, Qiu, Cong, & Ding, 2010). In the anomeric region of 1 HNMR, the resonances at 5.05 ppm and 4.99 ppm were assigned to terminal ␣-Glcp in different chemical environments, and 4.80 ppm was ascribed to 1, 4, 6-linked ␤-Manp.…”

Structural elucidation of a polysaccharide from Chrysanthemum morifolium flowers with anti-angiogenic activity

“…3C and D. The signals were assigned according to the HSQC, HMBC, 1 H-1 H COSY (Fig. S1) and literatures values [19][20][21], and the results were listed in Table 3. In the anomeric region of 1 H NMR spectrum, 5.15 ppm and 5.12 ppm were from 1,5-linked ␣-Araf and T-linked ␣-Araf, respectively.…”
