Effects of restoration years on soil stoichiometric ratios in subtropical secondary forests.

Soil stoichiometric ratios serve as valuable indicators for the composition and quality of soil organic matter. While available studies predominantly examine the soil stoichiometric ratios of carbon (C), nitrogen (N), and phosphorus (P), limited attention has been paid on the influence of forest restoration on soil stoichiometric ratios of potassium (K), calcium (Ca), and magnesium (Mg). We analyzed soil K, Ca, and Mg content, as well as elemental stoichiometric ratios, in secondary forests with varying restoration periods (5, 8, 21, 27 and 40 years) and a natural forest, in order to examine the impact of forest restoration on soil stoichiometry.

Investigating the Use of Magnetic Nanoparticles As Alternative Sintering Agents in Selective Laser Sintering (SLS) 3D Printing of Oral Tablets.

Selective laser sintering (SLS) is a single-step, three-dimensional printing (3DP) process that is gaining momentum in the manufacturing of pharmaceutical dosage forms. It also offers opportunities for manufacturing various pharmaceutical dosage forms with a wide array of drug delivery systems. This research aimed to introduce carbonyl iron as a multifunctional magnetic and heat conductive ingredient for the fabrication of oral tablets containing isoniazid, a model antitubercular drug, via SLS 3DP process.

Bioactive phenolic acid-substituted glycoses and glycosides from rhizomes of .

Two rarely phenolic acid-substituted alloses () and one new glucoside (), as well as nine known compounds () were isolated from rhizomes of (L.) J. Sm.

A Tri-O-Bridged Diels-Alder Adduct from Cortex Mori Radicis.

Sanggenon X, an unusual tri--bridged Diels-Alder adduct, was isolated from Cortex Mori Radicis. Its structure was established by spectroscopic analysis, including NMR and HR-MS (High Resolution Mass Spectrometry). Sanggenon X contained three -bridged rings, where the oxygenated bridgeheads were all quaternary carbons.

Hepatoprotective hemiterpene glycosides from the rhizome of Cibotium barometz (L.) J. Sm.

Five previously undescribed hemiterpene glycosides, cibotiumbarosides E-I, and two known hemiterpene glucosides, were isolated from the rhizome of Cibotium barometz (L.) J. Sm.

Bioactive Benzofuran Derivatives from Cortex Mori Radicis, and Their Neuroprotective and Analgesic Activities Mediated by mGluR₁.

Four new benzofuran-type stilbene glycosides and 14 known compounds including 8 benzofuran-type stilbenes and 6 flavonoids were isolated from the traditional Chinese medicine, Cortex Mori Radicis. The new compounds were identified as (9)-moracin P 3'--α-l-arabinopyranoside (), (9)-moracin P 9--β-d-glucopyranoside (), (9)-moracin P 3'--β-d-glucopyranoside (), and (9)-moracin O 10--β-d-glucopyranoside () based on the spectroscopic interpretation and chemical analysis. Three benzofuran-type stilbenes, moracin O (), R (), and P () showed significant neuroprotective activity against glutamate-induced cell death in SK-N-SH cells.

[Quality standard study on Mori Cortex liquid extract].

A reasonable and practicable quality standard was developed for mori liquid extract from different sources by TLC, HPLC and fingerprint technology. In TLC method, the compounds were separated on polyamide film using glacial acetic acid-water (1: 3) as mobile phase at a UV wavelength of 365 nm. All qualified samples had the spots of the same color as the control herb and substance.
