AI Article Synopsis

  • The study aimed to compare the chemical compositions of Dendrobium candidum and Dendrobium nobile using high performance liquid chromatography-mass spectrometry.
  • The findings revealed that D. nobile had a significantly higher relative area of alkaloids (41.87%) compared to D. candidum (2.34%), indicating notable differences in alkaloid content between the two species.
  • Despite D. nobile having more alkaloids, D. candidum exhibited a higher quality in terms of specific chemical compositions, suggesting it may be more favorable for certain applications.

Article Abstract

Objective: To compare the chemical compositions between Dendrobium candidum (D. candidum) and Dendrobium nobile (D. nobile).

Method: Relative area and content of every chromatographic peak in the ammonic chloroform extracts of D. candidum were compared with those of D. nobile with high performance liquid chromatography-mass spectrometry.

Results: The relative area of alkaloids accounted for 2.34% and 41.87% in D. candidum and D. nobile, respectively. The relative area of 25 identical compositions took up 97.12% in the total area of D. candidum and 50.09% in that of D. nobile, and contents of 23 composition were higher in D. candidum than those in D. nobile.

Conclusions: The quantity and contents of alkaloids are remarkably different between D. candidum and D. nobile. However, D. candidum has a higher quality than D. nobile in terms of the same chemical compositions.

Polyphenols, natural compounds abundant in phenolic structures, have received widespread attention due to their antioxidant, anti-inflammatory, antibacterial, and anticancer properties, making them valuable for biomedical applications. However, the green synthesis of polyphenol-based materials with economical and environmentally friendly strategies is of great significance. In this study, a multifunctional wound dressing was achieved by introducing polyphenol-based materials of copper phosphate-tannic acid with a flower-like structure (Cu-TA NFs), which show the reactive oxygen species scavenging performance.

The radiogenic isotopic compositions of basaltic Martian meteorites (shergottites) and clinopyroxene/olivine cumulate meteorites (nakhlite/chassignites) are used to define the global evolution of Mars. However, the two main groups of meteorites demonstrate that their sources underwent divergent styles of magmatic evolution. The shergottites portray a planet that differentiated ~4.

Copper(II) oxide nanoparticles (CuO NPs) are used in different industries and agriculture, thus leading to their release to the environment, which raises concerns about their ecotoxicity and biosafety. The main toxicity mechanism of nanometals is oxidative stress as a result of the formation of reactive oxygen species caused by metal ions released from nanoparticles. Bacterial biofilms are more resistant to physical and chemical factors than are planktonic cells due to the extracellular polymeric matrix (EPM), which performs a protective function.

Increasing aquaculture production requires high-density farming, which induces stress, necessitating supplements to mitigate its effects and ensure fish health. The aim of this study was to examine how CaNa2EDTA (EDTA) affects the growth, immune response and antioxidant activity in Nile tilapia (Oreochromis niloticus). The fish were raised at three different stocking densities: low (LD = 2.

Fibrillation of the amyloid beta (Aβ) peptide has often been associated with neurodegenerative pathologies such as Alzheimer's disease. In this study we examined the influence of several potential compositions of the lipid membrane on Aβ fibrillation by using liposomes as a basic model membrane. Firstly, it was revealed that Aβ fibrillation kinetics were enhanced and had the potential to occur at a faster rate on more fluid membranes compared to solid membranes.
