Merits of bioactivity and products of Dendrobium officinale and other related species.

The genus Dendrobium is a renowned traditional Chinese medicinal plant and one of the most extensively studied and widely applied species within the Dendrobium genus, possessing significant medicinal value and industrial development potential. This paper reviews the resource distribution and quality correlation, development trends, chemical constituents, biological activities, clinical applications, and current product development status of Dendrobium officinale and other medicinal plants within the Dendrobium genus. It highlights the structural characteristics and pharmacological effects of key active components such as polysaccharides, alkaloids, and dibenzyl compounds, summarizes their mechanisms of action in immune regulation, antioxidant properties, and eye health protection, and supplements the influence of different origins and cultivation models on active components. The paper also provides an outlook on the current status of product development and future trends.
