In this study, a high-performance thin-layer chromatography (HPTLC)-based method was developed for the quantification of five water-soluble vitamins, B2, B3, B6, B12, and C, using ethanol–water (70:30, v/v) as the mobile phase. The method was valid

This study reports on the analysis of eleven Jarrah (Eucalyptus marginata) honeys, of which nearly half (n = 5) were re-classified as Blackbutt (E. patens) honey on the grounds of the predominant flower pollen identified by melissopalynology. Based o
