Rp hplc diagram. A simple, rapid, precise and highly accurate RPHPLC method was developed and validated for determination of alphamangostin content extracted from PLGAmicrospheres Method was developed using a silicabased deactivated C18 column (46×100 mm, 3 μm) with a mobile phase of 7080 % v/v acetonitrile (A) and 01% v/v. The key difference between reverse phase and normal phase HPLC is that the reverse phase HPLC uses a nonpolar stationary phase and a polar mobile phase whereas the normal phase HPLC uses a polar stationary phase and a less polar mobile phase The normal phase HPLC is the oldest technique of HPLC that Tswett used in his separations of plant extracts;.

The elution order of solutes in HPLC is governed by polarity In a normalphase separation the least polar solute spends proportionally less time in the polar station ary phase and is the first solute to elute from the column. In RPHPLC, the primary mechanism dictating retention behavior is hydrophobic interaction between the nonpolar stationary phase ligand (eg C18) and the hydrophobic nature of the sample molecule (eg the carbon backbone) This is a weak, transient interaction between a nonpolar stationary phase and the molecules, which includes hydrophobic.
