ABSTRACT
<p><b>OBJECTIVE</b>To prepare the cubic phase gel containing capsaicin and characterize its properties.</p><p><b>METHOD</b>The cubic phases gel composed of glycerol monoolein, capsaicin and water was made by self-emulsion technology. The characterization of cubic phase gel was carried out by cross-polarizing light microscopy (CPLM) and Small Angle X-Ray Scattering (SAXS). The capsaicin content was determined by HPLC analysis.</p><p><b>RESULT</b>Under CPLM, cubic phase gel showed dark background. SAXS scattering spectra showed the scattering peaks at 0.1096, 0.1334, 0.1557, 0.1883 A(-1) which was compatible with q1q2q3q4 = mean square root of 2 mean square root of 3 mean square root of 4 mean square root of 6. It was well known that the scattering vector ratio was the characteristic of cubic phase and the internal structure was confirmed to be Pn3m (Q224). The linear range for capsaicin determination was 3.25 x 10(-4) - 2.08 x 10(-2) g x L(-1) (R2 = 1). The average recovery was 97.53% with RSD of 2.9% (n=9).</p><p><b>CONCLUSION</b>CPLM and SAXS technology are suitable to characterize the cubic phase gel The determination of the capsaicin content by HPLC is simple and reproducible.</p>
