Yield and composition of water soluble polysaccharides (mg/fruit)... 

Xanthan Gum. Xanthan gum is produced by the bacterium Xanthomonas campestris. Commercial productions started in 1964. Xanthans are water-soluble polysaccharide polymers with the following repeating units [502], as given in Table 17-5 and Figure 17-6. 

Dissolving from 0.2% to 1.0% by weight of a water-soluble polysaccharide in an aqueous solution... 

The glycoproteins and water-soluble polysaccharides contain mainly galactan with some araban.95...

Other chemical constituents include water-soluble polysaccharides, designated as panaxanes (Gruenwald et al. 1998). Acetylenic constituents include panaxynol, panaxydol, and panaxtryol (Matsunaga et al. 1995). 

For the reasons stated above, deep intrusion of degrading microbes into polysaccharide-plastic films is demonstrably and theoretically improbable. Since starch removal does occur when the films are buried in soil, the primary mechanism must be microbial production of amylase in or near a pore, diffusion of the enzyme into pores and diffusion of soluble digestion products back to the surface where they are metabolized (Figure 3). This mechanism would be the only choice when the pore diameter is too small to admit a microbial cell (i.e., at diameters < 0.5 /im). An alternative mechanism could be diffusion of a water-soluble polysaccharide to the film surface, at which point degradation would occur. None of the materials used in these investigations showed loss of starch even when soaked in water for extended periods with microbial inhibitors present. Therefore, diffusion of amylase to the substrate rather than diffusion of the substrate to the film surface is the more likely mechanism.

The three most widely used species of Echinacea are Echinacea purpurea, E pallida, and E angustifolia. The chemical constituents include flavonoids, lipophilic constituents (eg, alkamides, polyacetylenes), water-soluble polysaccharides, and water-soluble caffeoyl conjugates (eg, echinacoside, chicoric acid, caffeic acid). Within any marketed echinacea formulation, the relative amounts of these components are dependent upon the species used, the method of manufacture, and the plant parts used. Epurpurea has been the most widely studied in clinical trials. Although the active constituents of echinacea are not completely known, chicoric acid from E purpurea and echinacoside from E pallida and E angustifolia, as well as alkamides and polysaccharides, are most often noted as having immune-modulating properties. Most commercial formulations, however, are not standardized for any particular constituent. 

Keep volumes of buffer as small as possible to minimize losses of water-soluble polysaccharides from the cell walls. Record total buffer used. 

It should be appreciated that the water-soluble polysaccharides obtained during cell wall isolation are part of the cell wall and are to be treated as such. Take care with older isolation procedures as the water-soluble fractions were often discarded. 

Main actives Water-soluble polysaccharides and glycoproteins, volatile oil (up to 2%), caffeic and ferulic acid derivatives including cichoric acid (0.6-2.1%), alkamides (0.01-0.04%), polyynes and pyrrolizidine alkaloids. 

In recent years factors such as alkylresorcinals (8), trypsin inhibitors, (9,10) and water-soluble polysaccharides have been implicated in the poor feeding quality of rye. Investiga-...
