Research progress on the extraction,separation,and purification of chemical constituents from Dendrobium species
Dendrobium has long been referred to as the"gold in medicine"and is highly valued as a key component of traditional Chinese medicine.It is primarily the stems of Dendrobium that are used,containing a variety of compounds such as polysaccharides,alkaloids,flavonoids,bibenzyl analogs,phenolics,phenylpropanoids,alkenes,phytosterols,amino acids,trace elements,and volatile oils.Although the leaves and flowers of Dendrobium also contain numerous chemical constituents,the methods for separating and purifying these components are still not fully developed.This limitation has hindered the comprehensive utilization and development of Dendrobium.This review analyzes a substantial body of recent literature on Dendrobium species and explores their effective components,as well as the methods for extraction,separation,and purification of the stems,flowers,and leaves.Findings from this review help provide essential technical support for the comprehensive utilization of Dendrobium species and the future development of the Dendrobium industry.
