Dendrobium represents one of the most important orchid genera, ornamentally and medicinally. Dendrobiums are sympodial epiphytic plants, which is a name they are worthy of, the name coming from Greek origin: "dendros", tree, and "bios", life.

Dendrobium species, commonly known as "Shihu" or "Huangcao," represents the second largest genus of Orchidaceae, which are used commonly as tonic herbs and healthy food in many Asian countries. The aim of this paper is to review the history, chemistry, and pharmacology of different Dendrobium species on the basis of the latest academic literatures found in Google Scholar, PubMed, Sciencedirect,...

Chromatographic separation of a methanol extract prepared from the whole plant of Dendrobium brymerianum led to the isolation of eight phenolic compounds. Among the isolated compounds (1-8), moscatilin (1), gigantol (3), lusianthridin (4), and dendroflorin (6) showed appreciable cytotoxicity against human lung cancer cell lines with IC50 values of 196.7, 23.4, 65.0, and 125.8 μg/mL, respectivel...

A protocol for regeneration of an endangered medicinal orchid Dendrobium crepidatum was established mainly via indirect protocorm like body (PLBs) formation. The PLBs procured from in vitro growth cultures assessed ½ MS medium alone and combinations with 6-Benzyl amino purine (BAP), Kinetin (Kn) α-Naphthalene acetic acid (NAA). calli were induced longitudinally bisected segments PLBs. optimum p...

From the aerial parts of Dendrobium secundum, a new bibenzyl, namely 4,5,4'-trihydroxy-3,3'-dimethoxybibenzyl, was isolated, along with four known compounds which included brittonin A, moscatilin, syringaresinol, and ferulic acid. All of these isolates showed appreciable DPPH free radical scavenging potential, except for brittonin A, which was devoid of activity.
