Two new triterpenoid saponins, namely camsinsaponins A and B (1, 2), along with two known congeners (3, 4) were isolated from Camellia sinensis flowers. Their structures determined by extensive spectroscopic data. All compounds assessed for antifungal bioactivity against Candida albicans, glabrata, tropicalis. Compounds 1–4 showed excellent inhibitory effects. Notably, in regard to 1 2, their MIC values C. albicans close those of the positive control, fluconazole. Furthermore, elements on...
Understanding of the penetration behaviors pesticides in fresh produce is great significance for effectively applying and minimizing pesticide residues food. There lack, however, an effective method that can measure penetration. Herein, we developed a novel real-time situ monitoring spinach leaves based on surface-enhanced Raman scattering (SERS) mapping. Taking advantage penetrative gold nanoparticles (AuNPs) as probes to enhance internalized signals situ, have successfully obtained...
A total of 98 compounds including 20 aldehydes, eight arenes, six acids, 17 alcohols, 13 ketones, nine esters, methoxyphenolics, three alkenes, seven alkanes, and other components were tentatively identified in Chinese dark teas (CDTs) using gas chromatography-mass spectrometry. Multivariate statistical analysis revealed that from Yunnan Guangxi provinces could be classified into one group, CDTs belonged to the cluster. The diagnostic volatile being responsible for CDTs' discrimination...
A model system consisting of a nonsystemic pesticide (ferbam), engineered gold nanoparticles (AuNPs) and plant tissue (tea leaves) was investigated using surface enhanced Raman spectroscopy (SERS). Ferbam has no ability by itself to penetrate into tea leaves. When AuNPs were placed with ferbam onto the leaves, however, SERS signal ferbam-AuNPs complex observed inside Within 1 h, rapidly penetrated leaf depth approximately 190 μm, about (1)/3 (1)/2 leaf's thickness. The rate penetration...

Abstract Environmental and plant factors (soil condition, variety, season, maturity) exposure risks of aluminum (Al), manganese (Mn), lead (Pb), cadmium (Cd), copper (Cu) in tea leaves were investigated. The concentrations these metals could not be predicted by their total the soil. During any one there differences Al, Mn, Cd levels between varieties. Seasonally, autumn and/or summer had far higher Pb, than did spring tea. Tea leaf maturity positively correlated with Cd, but negatively Cu....
