Comparative study of UPLC–MS/MS and HPLC–MS/MS to determine procyanidins and alkaloids in cocoa samples

Comparison of Two Methods, UHPLC-UV and UHPLC-MS/MS, for the Quantification of Polyphenols in Cider Apple Juices

“…Because of the high number of samples, a fast phenotyping method was required and the UHPLC method seemed to be the most appropriate. Faster methods have been recently proposed to quantify polyphenols using more powerful chromatographic systems such as UHPLC coupled with a UV detector [15,16] or a mass analyzer [16,17].…”

Chromatographic separation techniques and data handling methods for herbal fingerprints: A review

“…Over the last few years, in many papers UHPLC fingerprints of herbal products were developed rather than the conventional HPLC approach [100][101][102][103][104][105][106][107][108][109][110][111][112]. Comparative studies between HPLC and UHPLC analyses on Hoodia, Cocoa, and Niu Huang Jie Du Pill samples reported a decreased analysis time by a factor up to eight without loss of information [102,111,112].…”

“…Comparative studies between HPLC and UHPLC analyses on Hoodia, Cocoa, and Niu Huang Jie Du Pill samples reported a decreased analysis time by a factor up to eight without loss of information [102,111,112]. In reference [113], UHPLC-DAD-TOF/MS analyses were performed on Danggui Buxue Tang samples allowing for the unambiguous identification of 39 constituents.…”

Determination of Antioxidant Compounds in Foodstuff

“…Several studies describe UPLC as being more sensitive than HPLC in the detection and quantification of antioxidant compounds from natural fi matrices such as ascorbic acid [203], vitamin E [204], procyanidins [205] and isoflavonoids [206]. fl High performance liquid chromatography-electrospray ionization mass spectrometry (HPLC/ESI-MS) is another chromatographic technique recently used for the detection and quantification of individual antifi oxidants [90].…”
