Research Situation of Polysaccharides of Dendrobii Officinalis Caulis

摘要

This study was conducted to investigate the changes of polysaccharides content in Dendrobii Officinalis Caulis and its pharmacological action. The results showed that different growth years,different periods,different habitats and different external factors had influences on the change of polysaccharide content in Dendrobii Officinalis Caulis. Dendrobii Officinalis Caulis has certain effects of enhancing immunity,resisting fatigue and oxidation,promoting digestion and salivation secretion,reducing blood sugar and blood pressure,resisting tumor and liver injury,and relaxing bowels. Dendrobii Officinalis Caulis polysaccharides are the main effective components in Dendrobii Officinalis Caulis. The control of Dendrobii Officinalis Caulis polysaccharide content is of great significance to the assurance of the yield and quality of Dendrobii Officinalis Caulis material.
