Two new bergamotane sesquiterpene lactones, named expansolides C and D (1 2), together with two known compounds A B (3 4), were isolated from the plant pathogenic fungus Penicillium expansum ACCC37275. The structures of established by detailed analyses spectroscopic data, especially 1D-, 2D-NMR, HR-ESI-MS. In an in vitro bioassay, epimeric mixture 2) (in a ratio 2:1 at temprature bioassay) exhibited more potent α-glucosidase inhibitory activity (IC50 =0.50 ± 0.02 mm) as compared positive...
In this study, the dried fruits of Rubus chingii Hu (Chinese name: Fu-Pen-Zi; FPZ) were processed and by three methods—in shade, sun, oven. The composition regarding standard ingredient, color, antioxidant capacities investigated pro- post-processing. technique headspace–solid-phase-microextraction–gas-chromatography–mass spectrometry (HS-SPME-GC-MS) flavoromics used to analyze flavor-conferring metabolites FPZ. results obtained revealed that highest use value detected in FPZ shade. A total...
Background: Although chromatography and spectrometry-based methods have been used to analyse phenolic acids in Chinese traditional medicine Salvia miltiorrhiza Bunge (SMB), quantitative nuclear magnetic resonance (qNMR) has never previously fresh SMB root extracts. Objective: To establish a fast simple method of quantitating danshensu, lithospermic acid, rosmarinic salvianolic acid B content using 1 H-NMR spectroscopy. Method: Fresh was extracted 70% methanol aqueous solution quantitatively...
