Objective: To investigate the chemical constituents of Epimedium brevicornum.
Method: The chemical constituents were isolated by using silica gel column chromatography and preparative TLC. The structures were identified on the basis of physical-chemical constants and spectral data.
Result: Five compounds were isolated and identified as hyperoside, icariin, epimedin B, epimedin C, inositol.
Conclusion: Compound I and III - V were isolated from the plant for the first time.

This study aimed to investigate the potential protective properties of a traditional Chinese medicine (TCM) herbal product, Siraitia grosvenorii granules (SGG) against PM2.5-induced lung injury, as well as their active constituents and underlying mechanisms. The chemical composition of SGG, such as wogonin (MOL000173), luteolin (MOL000006), nobiletin (MOL005828), naringenin (MOL004328), acacetin (MOL001689), were identified via ultra-high-performance liquid chromatography-Q Exactive (UHPLC-QE) Orbitrap/MS.

One new monomeric citrinin analog (1) and 42 known compounds (2-43) were isolated from Penicillium citrinum W22. The structure of 1 was determined by detailed analysis of the 1D and 2D nuclear magnetic resonance (NMR), HRESIMS, and time-dependent density functional theory (TD-DFT)-based electronic circular dichroism (ECD) calculation. Penicitrinol A (2) and methyl 2-(2-acetyl-3,5-dihydroxy-4,6-dimethylphenyl) acetate (11) significantly inhibited renin-angiotensin system-selective lethal 3 (RSL3)-induced ferroptosis with half maximal effective concentration (EC) values of 1.

Background: The composition of anaerobically digested sludge is inherently complex, enriched with structurally complex organic compounds and nitrogenous constituents, which are refractory to biodegradation. These characteristics limit the subsequent rational utilization of resources from anaerobically digested sludge. White-rot fungi (WRF) have garnered significant research interest due to their exceptional capacity to degrade complex and recalcitrant organic pollutants.

Predictive approaches and rules to connect and combine molecular circuit components are required to realize the potential of molecular electronics and develop miniaturized integrated circuits. To this end, we have recently demonstrated a bis(terpyridine)-based molecular breadboard with four conductance states formed by the superposition of five 2-5 ring circuits. Here, we develop a generic analytical/statistical model to describe break-junction data and use it to extract the conductance of the five embedded circuits in the bis-terpyridine-based molecular breadboard junction.

One new azaphilone derivative () from in ordinary medium, one new phthalide derivative (), a microbial transformation product of ingredients by , a pair of new austdiol enantiomers (+)- and (-)-, one new epsilon-caprolactone derivative (), and one new ophiobolin-type sesterterpenoid () from the in host medium were reported. The structures were determined by spectroscopic analysis and single-crystal X-ray diffraction. Compounds - could completely inhibit the germination of rice seeds at 50 μg/mL, which is higher than that of the positive control.
