Quantitative
determination of capsaicin in liniments by microemulsion liquid chromatography
Abstract
The
technique of quantitative determination of capsaicin in liniments by
microemulsion liquid chromatography method was proposed. Due to the absence of
the homogenization, extraction and filtration stages, the procedure of sample
pretreatment takes 5 minutes, what is much more rapid in comparison with the
variants, described in the literature (from 30 minutes to 12 hours). The full
time of the analysis (including the procedure of sample pretreatment) is 20
minutes. The graduation curve is linear in the range from 0,02 to 240 mg/l. the
limit of determination of capsaicin was 8 mkg/l.
