Objective: To establish an FTIR method for the analysis of Dendrobium.
Method: Using fourier transform infrared spectrometer to record the characteristic spectra of eleven samples of Dendrobium, and to compare the spectra by PCA (principal component analysis).
Result: The FTIR spectra of the upper part of the stem displayed significant differences between fresh and dried samples of Dendrobium. On the other hand, differences were observed in the spectra of the middle and lower parts of stems of D. guangxieuse when compared to other species.
Conclusion: The method of applying PCA to FTIR analysis is a rapid and dependable method for comparing samples of Dendrobium.

The identification of natural active compounds is typically a cumbersome and time-intensive process due to the necessity for elaborate sample pretreatment, leading to inefficiencies. Although recent advancements have introduced methods for targeted screening of these active compounds, they still demand intricate sample handling, and in severe cases, critical active compounds may be lost or degraded beyond detection. This study capitalizes on the novel discovery that FeO magnetic nanoparticles (MNPs) can be stably immobilized onto a magnetized steel probe of the electrostatic field induced spray ionization mass spectrometry (EFISI-MS) platform.

Introduction: With its distinctive evolutionary rate and inheritance patterns separate from the nuclear genome, mitochondrial genome analysis has become a prominent focus of current research. Rolfe, a species of orchid with both medicinal and horticultural value, will benefit from the application of the fully assembled and annotated mitochondrial genome. This will aid in elucidating its phylogenetic relationships, comparative genomics, and population genetic diversity.

Objective: Dendrobin A, a typical active ingredient of the traditional Chinese medicine Dendrobium nobile, has potential clinical application in cancer treatment; however, its effect and mechanism in anti-hepatocellular carcinoma (HCC) remain unsolved.
Method: The effects of Dendrobin A on the viability, migration, invasion, cycle, apoptosis, and epithelial-mesenchymal transition of HepG2 and SK-HEP-1 cells were verified by in vitro experiments. mRNA sequencing was performed to screen the differentially expressed genes (DEGs) of HCC cells before and after Dendrobin A treatment, following GO enrichment and KEGG signaling pathway analyses.
