Ethyl acetate wash over the HP20SS column increases extract recovery. Samples of turmeric (Curcuma longa), paw paw (Asimina triloba), and tangerine (Citrus reticulata) extracts (30 mg) were subjected to HP20SS column chromatography with a water-MeOH system. The mass recovered without (open bar) or with (solid bar) an EtOAc wash was recorded. Data shown are average + standard deviation from three separate columns. Student’s paired t-test (two-tailed) was performed to compare the data using GraphPad Prism 5.0. Differences between data sets were considered statistically significant when p < 0.05 (** p < 0.01, *** p < 0.001).
