Natural-derived porous nanocarriers for the delivery of essential oils.

Essential oils (EOs) are natural, volatile substances derived from aromatic plants. They exhibit multiple pharmacological effects, including antibacterial, anticancer, anti-inflammatory, and antioxidant properties, with broad application prospects in health care, food, and agriculture. However, the instability of volatile components, which are susceptible to deterioration under light, heat, and oxygen exposure, as well as limited water solubility, have significantly impeded the development and application of EOs.

Intestinal microbiota-mediated serum pharmacochemistry reveals hepatoprotective metabolites of Platycodonis Radix against APAP-induced liver injury.

The urgent need for new medications that regulate CYP2E1, CASP3, Nrf2, HO-1, TLR2, TLR4, STAT3, and NF-κB activities is paramount for the treatment of drug-induced liver injury (DILI), particularly from acetaminophen (APAP). Previous studies have suggested that platycosides of Platycodonis Radix exhibits hepatoprotective properties against APAP-induced liver injury (AILI), and their serum metabolites may be the effective agents. As the identify the serum metabolites of platycosides is a huge challenge, the mechanism whether platycosides exert effects through the serum metabolites regulating those targets still remain unclear.

Pickering emulsions embedded in Bletilla striata polysaccharide based nanogel for enhancing skin-whitening effect of essential oils.

To improve the retention time and skin-whitening efficacy of Atractylodes macrocephale essential oil (AMO), a novel Pickering emulsion based nanogel loaded with AMO (AMO-PEG) was successfully developed. This formulation employed nano-pearl powder (NPP) as the particle stabilizer for the Pickering emulsion and Bletilla striata polysaccharide (BSP) as the gel matrix. The pH, rheological properties, hardness, and elasticity of AMO-PEG were affected by the ratio of AMO-Pickering emulsion (AMO-PE) to BSP gel matrix.

A fragmentation study of disaccharide flavonoid C-glycosides using triple quadrupole mass spectrometry and its application for identification of flavonoid C-glycosides in Odontosoria chinensis.

Rationale: Flavonoid C-glycosides have a wide range of pharmacological activities. However, there are few mass spectrometric research on C,O-disaccharide flavonoid C-glycosides and di-C,O-saccharide flavonoid C-glycosides. Their low-energy collision-induced dissociation (ESI-CID-MS/MS) fragmentation pattern and differences have not been reported, and the fragment ion library is incomplete.

Epiphytic Patterns Impacting Metabolite Diversity of Rhizomes Based on Widely Targeted Metabolomics.

Nakaike, a fern widely distributed in China and some countries in Southeast Asia, is a commonly used herbal medicine in tonic diets and Chinese patented medicine. The metabolites of its dried rhizomes are easily affected by the epiphytic pattern, whether on rock tunnels (RTs) or tree trunks (TTs). The current research focused on rhizomes from these two patterns, RTs and TTs (further divided into subclasses TA, TB, TC, and TD, based on trunk differences) and conducted a widely targeted metabolomics analysis.
