Chromatographic medium-dependent sample recovery of plant extracts. Samples of cranberry (Vaccinium macrocarpon), paw paw (Asimina triloba), and pomegranate (Punica granatum) extracts (30 mg; 150 μL stock solution) were subjected to HP20SS (striped bar) and Si gel (solid bar) column chromatography. The amount of recovered sample was presented as “% Sample Recovery.” As a control for drying-associated sample loss, extract samples were placed in vials, dried, and the dried materials served as sample recovery control (open bar). Data shown are average + standard deviation from three separate columns or vials, as appropriate. One-way ANOVA with the Bonferroni post hoc test was applied to analyze the data using GraphPad Prism 5.0 and differences between data sets were considered statistically significant when p < 0.05.
