Abstract:

To confirm the optimal harvesting time, the dynamic changes of alkaloids and polysaccharides in mass fraction in Dendrobium nobile Lindl were determined in March, September, October, November, and December and high mass fraction of polysaccharides were determined in October and November. The most appropriate harvest time is from October to November.

Key words: Dendrobium nobile Lindl, alkaloids, polysaccharides, harvest time
