Structural characterisation of a water-soluble polysaccharide with high branches from the leaves of Taxus chinensis var. mairei

Medium optimization and structural characterization of exopolysaccharides from endophytic bacterium Paenibacillus polymyxa EJS-3

“…The bands in the region of 1500 and 1200 cm À1 were assigned to C-H deformation vibration (Hineno, 1977). The bands between 1128 and 1014 cm À1 corresponded to C-O-C and C-O-H stretching vibration (Wu, Wu, Zhou, & Pan, 2009). A characteristic absorption at 926 cm À1 was resulted from the stretching vibration of pyran ring (Schwanninger, Rodrigues, Pereira, & Hinterstoisser, 2004).…”

Chemical characterization and in vitro antitumor activity of a single-component polysaccharide from Taxus chinensis var. mairei

“…Therefore, the relationship between structure and activity was ambiguous, and was not conducive to the further development of these polysaccharidse. In our previous work, T1, a water-soluble polysaccharide from Taxus chinensis, was investigated regarding its structure (Wu, Wu, Zhou & Pan, 2009). As an extension of our research on the polysaccharides of Taxus chinensis, in the present study, we report on the extraction and purification of a major polysaccharide of Taxus chinensis using ion-exchange column and gel permeation column chromatography.…”

A Microwave-Assisted Simultaneous Distillation and Extraction Method for the Separation of Polysaccharides and Essential Oil from the Leaves of Taxus chinensis Var. mairei

“…The most well-known member of this class is taxol, which is an anti-cancer agent used in the clinic for the treatment of ovarian and breast cancers [2]. With the further study of Taxus, some the other bioactive components with human health benefits, such as, polysaccharide and essential oil were found and have attracted considerable attention throughout the world [3,4].…”

“…mairei possess potent antitumor, antidiabetic, and immunity enhancing activities [3,5,6]. milled and passed through 40 mesh, 60 mesh, 80 mesh, and 100 mesh sieves, in turn.…”
