Chemical Differentiation of Dendrobium officinale and Dendrobium devonianum by Using HPLC Fingerprints, HPLC-ESI-MS, and HPTLC Analyses

<div>Typical HPLC chromatograms of extracts from dried stems of D. officinale and D. devonianum. Fifteen common peaks were found in D. officinale stems and D. devonianum stems, and obvious differences were shown in 20 min to 40 min in their fingerprint, indicating that the HPLC fingerprints could serve as an efficient quality control tool for differentiating D. officinale and D. devonianum.</div>
