- Herba Dendrobii has been documented in the Compendium of Materia Medica, with special efficacy in nourishing Yin and treating diabetes. However, the chemical profile of Dendrobium chrysanthum Lindl. has not been reported yet. The compositions were analysed with UPLC/Q-TOF-MS/MS. 53 compounds were tentatively characterised, and 14 compounds might be new compounds. Some novel lactones of poly-phenylpropanoids were firstly detected, and di-p-hydroxyphenylpropionic acidic p-coumaric acid lactone, a new compound of the first example, was obtained and identified. UPLC/Q-TOF-MS/MS was a feasible and efficient method to discover the unique compounds in complex matrices of D. chrysanthum.
