HPLC–ELSD/PDA combined with HPSEC–MALLS–RIDmolecular weightquality markers (Q-marker)red ginseng polysaccharidesRed ginseng (RG) has been extensively utilized in Asian countries due to its pharmacological effects. For the quality evaluation of RG, small molecules, such as ginsenosides, have been ...
We present a green, eco-friendly, novel, sensitive, rapid, robust, and three simple methods including the HPLC-PDA, HPLC-FLD, and HPLC-ELSD approach for the simultaneous determination of MEL in various products. The mobile phase of all the HPLC methods consists of only water and an ethanol...
HPLC-ELSDLC-MSOptimized extractionSyzygium formosumSyzygium formosum (SF) leaves have been used for thousands of years in traditional Vietnamese medicine for the treatment of allergy or skin rash. However, the role of the phytochemical profile of SF leaves on their activities is poorly understood....
HPLC–ELSD/PDA combined with HPSEC–MALLS–RID could be used to determine the contents of disaccharides, molecular weights, and compositional monosaccharides of RG polysaccharides, which could be used for quality control, and this is a new view on the sugar marker to quality differentiation of ...
The content of the chikusetsusaponin IVa was detected 0.216±0.004mg/freeze-dried extract g (PDA) and 0.203±0.004mg/ freeze-dried extract g (ELSD). The established HPLC assay could be used as a basis for quality assessment of products containing D. lablab and/or D. lablab....
