This study aims to evaluate the in vitro vasorelaxant effect of C. nobile aqueous extract. We use aortic ring isolated from Wistar rats and aqueous C. nobile extract at doses of 5, 10 and 20 mg/ml. Incubation of aqueous C. nobile extract for 30 minutes produced a significant shift of the dose-response curve to norepinephrine (NE) (10(-8) to 10(-5) M) (p < 0.001). This study demonstrates that aqueous C. nobile extract possesses in vitro vasorelaxant effect.

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.

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.

The aim of our study is to evaluate anti-inflammatory effect of Chamaemelum nobile. Aqueous extracts were administrated to Wistar rats in bronchial-inflammation experimentally induced by an allergen and ovalbumin, administered intraperitoneally / intranasally (20mg/kg/day). Experimentation showed disturbances in bronchoalveolar fluid with increased leukocyte and lymphocyte levels as well as IL-4 concentration in the lungs and erythrocytes associated with high lipid peroxidation.

With respect to the Parkinson's disease (PD), herein, we aimed at synthetizing and characterizing two novel macromolecular conjugates where dopamine (DA) was linked to N,O-carboxymethyl chitosan or O-carboxymethyl chitosan, being both conjugates obtained from an organic solvent free synthetic procedure. They were characterized by FT-IR, H NMR spectroscopies, whereas thermal analysis (including Differential Scanning Calorimetry and Thermal Gravimetric Analysis) revealed good stability of the two conjugates after exposure at temperatures close to 300 °C. Release studies in simulated nasal fluid elucidated that a faster release occurred since O-carboxymethyl chitosan-DA conjugate maybe due to the less steric hindrance exerted by the polymeric moiety.
