Preparation and purification of novel phosphatidyl prodrug and performance modulation of phosphatidyl nanoprodrug

“…If the proportion of sample to adsorbent is greater than 10 mg/g (Table 3), this would lead to overload. Normally, separation efficiency will decrease concomitant with an increase in the ratio of sample to adsorbent, due a reduction in the available interaction surface area (Melwita et al 2011). The results shown in Table 3 indicate that the optimal loading amount on the silica gel column was 10 mg/g, which gave a recovery of 44.02% ± 0.02%.…”
