HPTLC determination of xanthohumol in Hops (Humulus lupulus L.) and Hop Products
Kac, Javor ; Mlinarič, Aleš ; Umek, Andrej, 1951-
A sensitive thin layer chromatography method has been developed for the quantification of xanthohumol in hops (Humulus lupulus L.) and hop products. Chromatographic separation was performed on silica ...gel 60 HPTLC plates with toluene-dioxane-acetic acid, 77 + 20 + 3 (vžv), as mobile phase. The plates were scanned densitometrically at = 368 nm. The method was validated for precision, repeatability, and accuracy. It was found to be precise - intra-dayand inter-day RSD were 1.7 % and 2.3 %, respectively. Instrumental precision and repeatability of the method were found to be 0.38 and 1.5 (%CV),respectively. The accuracy was checked by studying the recovery at threelevelsč average recovery was 103.9 %. The method was used for the estimation of xanthohumol in hop extracts and xanthohumol-enriched beer and was confirmed to be suitable for this purpose.
