Objective: This study was conducted to evaluate the percutaneous absorption of aconitine and mesaconitine in extracts of Radix Aconitum kusnezoffii.
Methods: The extracts of Radix Aconitum kusnezoffii were collected by using Franz diffusion cells after permeation through the skin of rats. Then rate constants of skin permeation of aconitine and mesaconitine were determined by high-performance liquid chromatography (HPLC).
Results: Under the condition that the concentrations of azone and propylene glycol were both 4%, the cumulative doses of skin permeation (Q) of mesaconitine and aconitine in the extracts of Radix Aconitum kusnezoffii (600 mg/ml) for 24 hours were 165.819 and 487.747 microg/cm(2) respectively, and their rate constants of skin permeation were 18.391 and 78.805 microg.cm(-2).h(-1) respectively.
Conclusion: The aconitine and mesaconitine in the extracts of Radix Aconitum kusnezoffii can penetrate well through the skin of rats. Propylene glycol and azone can promote this penetration effects. The formula of skin permeation of mesaconitine and aconitine is in accordance with Higuchi equation and there is a linear relationship between Q and t(1/2).

Thunberg is a perennial herbaceous plant of the genus that belongs to the Apiaceae family and is effective in improving inflammation, gout, and dizziness. However, the skin pruritus improvement effect and mechanism of action of Thunberg root extract (PJRE) have not yet been reported. We investigated the effects of PJRE on the regulation of pruritus and inflammatory responses in compound 48/80 (C48/80)-treated mice, phorbol 12-myristate 13-acetate (PMA)/A23187-induced human skin mast cells, and LPS-stimulated mouse macrophages.

Chemical investigations of the -butanol extract of the roots of were carried out using column chromatography, flash, semi-preparative HPLC, and chiral HPLC. Five unidentified compounds, including two prenylated coumarin glucosides, two prenylated furanocoumarin glucosides, and a benzofuran glucoside, together with twelve known compounds, were isolated from the -butanol fraction of extract. The structures of these compounds were identified by HRMS, NMR, UV, ECD in combination with quantum chemical calculations, and comparison with the literature.

Turmeric (Curcuma longa) exhibits anti-obesity properties, yet its low water solubility limits bioavailability. In this study, a water-dispersible turmeric rhizome extract (WDTE) was developed using nano-dispersion technology with maltodextrin as a wall material and characterized by UPLC-QTOF-MS, dynamic light scattering, and zeta potential analysis. The WDTE contained 10 identified metabolites, including five diarylheptanoids such as curcumin, demethoxycurcumin, and bisdemethoxycurcumin, with curcumin quantified at 7.

The effect of mixed potable and wastewater (WW) irrigation on leafy vegetables cultivated in southern Tehran, Iran, was investigated in 2022. Eight species-spinach (Spinacia oleracea), scallion (Allium fistulosum), radish (Raphanus sativus), cress (Lepidium sativum), basil (Ocimum basilicum), purslane (Portulaca oleracea), cilantro (Coriandrum sativum), and savory (Satureja hortensis)-were grown in calcareous loamy soil under greenhouse conditions using five irrigation regimes (0%, 25%, 50%, 75%, and 100% WW) applied every 2 days. Soil salinity, DTPA-extractable Co, Cu, Ni, and Zn, plant growth traits, and health risk indices-transfer factor (TF), bioaccumulation factor (BAF), average daily dietary intake (ADD), hazard quotient (HQ), and cancer risk (CR)-were determined for children and adults.
