Isolation and characterization of the xylans of the cotton plant

  • Published:
Chemistry of Natural Compounds Aims and scope

Summary

1. The specific rotations and molecular weights of the xylans isolated from the stems, boll valves, and seed husks of the cotton plantGossypium hirsutum (family Malvaceae) have been determined.

2. The homogeneity of the xylan preparations has been shown by their fractionation by precipitation from aqueous solutions with increasing concentrations of ethanol and by gel filtration on Sephadex G-75.

3. Dextrorotatory xylans have been isolated from the plants and the simultaneous presence of the optical isomers of the xylans in the one plant has been established for the first time.
