Paclitaxel (PTX) is a complex diterpenoid anticancer drug whose separation from yew biomass poses a significant challenge. In this study, a new stationary phase comprising hydrogenated rosin (β-acrylo...
Comparison of diferent aroma active compounds of Sichuan Dark brick tea (Camellia sinensis) and Sichuan Fuzhuan brick tea using gas chromatography–mass spectrometry (GC–MS) and aroma descriptive profle tests
aroma active compounds Sichuan Dark brick tea Sichuan Fuzhuan brick tea GC–MS aroma descriptive profle tests
2024/7/31
Sichuan dark brick tea (Camellia sinensis) and Sichuan Fuzhuan brick tea have signifcantly diferent aroma characteristics although both of them have almost the same processing methods. Thus, these two...
Preparation of rosin-based polymer microspheres as a stationary phase in high-performance liquid chromatography to separate polycyclic aromatic hydrocarbons and alkaloids
rosin-based stationary phase alkaloids polycyclic aromatic hydrocarbons polymer microspheres
2024/3/8
Acrylpimaric acid ethylene glycol acrylate was used as the cross-linking agent to prepare rosin-based polymer microspheres through membrane emulsification-microsuspension polymerization. The prepared ...
Folate intake of the Dutch population according to newly established liquid chromatography data for foods
Folate folate intake consumption survey
2016/6/13
Determining folate intake is difficult because
existing folate data in food-composition tables are scarce and
unreliable.
