Article Abstract
Objective: To study flavonoids in Scutellaria barbata and elucidate their structures.
Method: Compounds were isolated and purified by normal column chromatography, paper thin layer chromatography and Sephadex chromatography. The chemical structures were elucidated by ESI mass and NMR spectra.
Result: Five flavonoids were isolated from S. barbata and identified as apigenin (1), luteolin (2), ethyl-7-O-apigenin-glucuronate (3), apigenin-7-O-beta-glucoside (4), and apigenin-7-O-neohesperidoside (5), in addition to benzyaldehyde (6).
Conclusion: Flavonoidglycoside (3), (4) and (5) were isolated from S. barbata for the first time.

Five new secoiridoids, gentianopsins A-E (1-5), along with two known analogues (6 and 7) were isolated from the whole plants of the medicinal herb Gentianopsis barbata. Their structures were elucidated by a comparison of extensive spectroscopic analysis (1D and 2D NMR, and HRMS) and quantum chemical calculations. Gentianopsins A (1) and B (2) represented two unusual skeletons of trihomo-secoiridoids.

The efficient removal of lead ions at low concentrations is paramount in combating the significant threat posed by water pollution resulting from industrial activities and population growth. In this study, electrospun /PAN fibers were developed to efficiently remove lead(II) ions from water. The morphology, structure, and mechanical properties of the fibers were examined, highlighting that the augmentation of the surface area through the conversion of into the polymer fibers facilitates increased metal bonding sites during sorption.

Since usnic acid was first isolated in 1844 as a prominent secondary lichen metabolite, it has been used for various purposes worldwide. Usnic acid has been claimed to possess numerous therapeutic properties, including antimicrobial, anti-inflammatory, antiviral, anti-proliferative, and antipyretic activities. Approximately two decades ago, crude extracts of usnic acid or pure usnic acid were marketed in the United States as dietary supplements for aiding in weight loss as a "fat-burner" and gained popularity in the bodybuilding community; however, hepatotoxicity was documented for some usnic acid containing products.
