[Advances in research of chemical constituents and pharmacological activites of Ephedra].

ABSTRACT

The collected information is an attempt to cover the more recent developments in the phytochemistry and pharmacology of this genus. During the past years, alkaloids, flavonoids, volatile oils, organic acids, polysaccharides, tannins and phenolic constituents have been isolated from Ephedra. Pharmacological studies are described according to hypoglycemic effects, anticoagulated blood properties, depressurization, immunosuppressive activity, antioxidation and antivirus activity and so on. The information summarized here is intended to provid a rational foundation for the futher development and utilization of Ephedra which is rich in China.
