Comparative metabolomic analyses of Dendrobium officinale Kimura et Migo responding to UV-B radiation reveal variations in the metabolisms associated with its bioactive ingredients

Background Dendrobium officinale Kimura et Migo , a member of the genus Dendrobium , is a traditional Chinese medicine with high commercial value. The positive roles of UV-B radiation on active ingredient metabolism in various medicinal plants have been studied. However, the metabolic responses of D. officinale stems to UV-B treatment is largely unknown. Methods An untargeted metabolomics method was used to investigate the metabolic variations...
