Research progress and predictive analysis of quality markers in Tibetan medicinal materials of Gymnadenia genus
The Tibetan medicinal materials of the Gymnadenia genus of Orchidaceae include Gymnadenia conopsea(L.)R.Br.,G.orchidis Lindl.,G.crassinervis Finet and G.bicornis T.Tang,G.emeiensis K.Y.Lang,which can be used as Shouzhangshen of Tibetan medicinal materials and have the effects of accelerating blood circulation,replenishing kidney essence.In recent years,it has been found that G.conopsea and G.orchidis have the pharmacological activities of preventing and treating Alzheimer's disease,anti-tumor and hypoglycemic activity.In this paper,the traditional application,chemical composition and pharmacological activity of Gymnadenia genus plants were reviewed.Furthermore,the quality markers of Gymnadenia genus plants were predicted and analyzed,to provide reference for the development and utilization of the Tibetan medicinal materials of Gymnadenia genus and quality standard research in the future.
