Research Progress on the Historical Evolution and Quality Formation of Dendrobium Officinale
Dendrobium officinale has always enjoyed the reputation of"the head of the nine immortal grasses in China",and is also one of the rare and endangered species."Dendrobium"in ancient and modern classics is the general name of Dendrobium plants.The term D.officinale first appeared in the Republic of China and was listed separately from the"Dendrobium"in the Chinese Pharmacopoeia in 2010.The origin of D.officinale is well documented in ancient and modern classics,with Anhui,Zhejiang,Guangdong,Jiangxi,Yunnan,Sichuan,and other regions being all suitable for its production.Evaluation on its quality the high-quality"Dendrobium"with"green stone","color gold","short and medium fruit or fine fruit","small and knotted stem"in the traditional Chinese medicine of all dynasties should refer to"D.officinale"and"D.huoshanense".Modern research has shown that light,temperature and humidity,endophytic fungi,enzymes,and genes are the main factors affecting the synthesis and accumulation of active components such as polysaccharides,total alkaloids,and total flavonoids in D.officinale.This article aims to provide an overview of D.officinale from the aspects of herbaceous research,origin evolution,quality evaluation,and factors affecting its quality formation,in order to provide important references for optimizing modern cultivation and planting modes of D.officinale and improving its quality.
