Bozkus, Tugba Nigar; Deger, Orhan; Yasar, Ahmet published an article in 2021, the title of the article was Chemical characterization of water and ethanolic extracts of Turkish propolis by HPLC-DAD and GC-MS.Name: N,N-Diethylacetamide And the article contains the following content:
This study aims to determine the qual. and quant. contents of Turkish propolis collected from various regions of Turkey using high-performance liquid chromatog. with the diode-array detector (HPLC-DAD) and gas chromatog.-mass spectrometry (GC-MS) in water and ethanolic extracts In HPLC-DAD analyses, it was determined that water extract of Turkish propolis contains phenolic acids such as caffeic acid (204.00 渭g/mL), trans-cinnamic, chlorogenic, and caffeoylquinic acids, responsible for its antioxidant activity; whereas, the ethanolic extract of Turkish propolis contains chrysin (641.33 渭g/mL), caffeic acid phenethyl ester (630.67 渭g/mL), pinocembrin (572.67 渭g/mL), galangin (534.11 渭g/mL), naringenin (372.39 渭g/mL), and also kaempferol, trans-cinnamic acid, caffeic acid, myricetin, and quercetin. GC-MS analyses showed that ethanolic extract of propolis contains caffeic acid by Rtx-1 column and the water extract of propolis contains quinic acid and ferulic acid by Rtx-5ms column. Various sugar derivatives were detected by both columns in water and ethanolic extracts of Turkish propolis. HPLC-DAD can be considered as a more effective method than GC-MS for the chem. characterization of propolis. Water extract of Turkish propolis can be a good source of raw materials for various sectors, as it is both cheap and has less health risk than ethanolic extract, and is suitable for human use. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Name: N,N-Diethylacetamide
The Article related to water ethanolic extract propolis liquid gas chromatog mass spectrometry, Placeholder for records without volume info and other aspects.Name: N,N-Diethylacetamide
