Antioxidant activity and potential hepatoprotective effect of polysaccharides from Cyclina sinensis

Characterization and biological activities of a novel polysaccharide isolated from raspberry ( Rubus idaeus L.) fruits

“…3. The intense broad band around 3430 cm −1 and the weak absorption band at about 2932 cm −1 were due to O H and C H stretching vibration, respectively (Jiang et al, 2013). Furthermore, the absorption peaks of 1732 and 1621 cm −1 were attributed to the absorption of ester carbonyl ( COOR) groups and carboxylate ion stretching band ( COO ), respectively , which was consistent with the result of carbazole-sulphuric acid reaction.…”

Optimized ultrasonic-assisted extraction of polysaccharides fromCyclina sinensisand evaluation of antioxidant activities in vitro

“…In addition, it has been reported that C. sinensis can be used for the treatment of asthma, inflammation and dental ulcer in traditional Chinese medicine (Wang et al, 2007). The latest study reported that the heat-extracted polysaccharides from C. sinensis (PCS) had potential hepatoprotective effects in vivo (Jiang, et al, 2013). However, to the best of our knowledge, there were no reports of systematic studies on ultrasonic-assisted extraction and biological activities of PCS compared with those of some other bivalvia species such as Mactra veneriformis, Mytilus coruscus and Hyriopsis cumingii (Xu et al, 2008;Qiao et al, 2009;Luan, Wang, Wu, Jin, & Ji, 2011).…”

A polysaccharide from Huaier induced apoptosis in MCF-7 breast cancer cells via down-regulation of MTDH protein

“…The results were consistent with the results of chemical analyses. The characteristic intense broad band at 3434.24 cm −1 was assigned to the hydroxyl O-H stretching vibration and the weak signal at 2924.52 cm −1 was attributed to C-H stretching vibration (Jiang, et al, 2013). Bands visible at approximately 1428.12 and 1374.47 cm −1 were ascribed to the angle vibration of C-H bond (Chen et al, 2008;Shao et al, 2014), whilst a band at 1043.11 cm −1 was indicative of the presence of non-symmetric C-O-C stretching vibration (Ding et al, 2012).…”
