Pharmacokinetics and tissue distribution of key sesquiterpene glycosides in Dendrobium nobile analyzed by UHPLC-Q-Trap-MS/MS.

Dendrobium nobile (D. nobile), a traditional herb known for its immunomodulatory and neuroprotective properties, contains characteristic alkaloids and sesquiterpene glycosides. While alkaloids have been extensively studied, research on sesquiterpene glycosides remains limited.

Quantitative analysis of six sesquiterpene glycosides from Dendrobium nobile Lindl. under different growth conditions by high-performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry in MRM mode.

Introduction: The sesquiterpene glycosides (SGs) from Dendrobium nobile Lindl. have immunomodulatory effects. However, there are no studies on the growth conditions affecting its contents and quantitative analysis methods.

Metabolites rapid-annotation in mice by comprehensive method of virtual polygons and Kendric mass loss filtering: A case study of Dendrobium nobile Lindl.

With significant advancements in high-resolution mass spectrometry, there has been a substantial increase in the amount of chemical component data acquired from natural products. Therefore, the rapid and efficient extraction of valuable mass spectral information from large volumes of high-resolution mass spectrometry data holds crucial significance. This study illustrates a targeted annotation of the metabolic products of alkaloid and sesquiterpene components from Dendrobium nobile (D.

Melatonin and Indole-3-Acetic Acid Synergistically Regulate Plant Growth and Stress Resistance.

Plant growth and development exhibit plasticity, and plants can adapt to environmental changes and stress. Various phytohormones interact synergistically or antagonistically to regulate these responses. Melatonin and indole-3-acetic acid (IAA) are widespread across plant kingdom.
