Objective To study the preparation technology anddetermination of compound tetrahydropalmatine pain relief gel. MethodsOrthogonal test was performed to determine the prescription ratio of thegel. RP-HPLC method was adopted. The determination was performed onEclipce XDB-C18 ( ${200}\mathrm{\;{mm}}\times {4.6}\mathrm{\;{mm}},{5\mu}\mathrm{m}$ ) column with mobile phase consisted ofmethanol-0.6% glacial acetic acid (pH 6.0) 30 : 70 . The detectionwavelength was ${280}\mathrm{\;{nm}}$ , the flow rate was $1\mathrm{\;{mL}}/\mathrm{{min}}$ .Results With $1\mathrm{\;g}$ carbomer ${940},{20}\mathrm{\;g}$ propyleneglycol, $8\mathrm{\;g}$ glycerol, ${0.5}\mathrm{\;g}$ triethanolamine as thegel matrix, the linear ranges of tetrahydropalmatine and imperatorinwere ${16.1}\sim {96.6}\mathrm{{\mug}}/\mathrm{{mL}}\left({r ={0.9999}}\right)$ and ${10.4}\sim {62.4}\mathrm{{\mug}}/\mathrm{{mL}}$ $\left({r={0.9999}}\right)$ , respectively. The average recoveries were99.13%(RSD was 0.79%) and 99.26%(RSD was 0.82%), respectively.
