TLC method is provides a chromatographic plant extract
fingerprint. In our study the capsaicin spot was
analogous to the reference spot confirming the
qualitative test. The HPLC chromatogram was obtained
with a commercial capsaicin using absorbance at 280 nm.
The sample gave a chromatogram of capsaicin and
dihydrocapsaicin along with minor amounts of the other
capsaicinoids
