This is my capsaicin standard
run on HPLC, any reason why im getting two peaks?
Homework Answers
The second peak is due to the dihydrocapsaicin.Since the molecular structure of both capsaicin and dihydrocapsaicin are very similar the maximum absorption wavelength are determined.Identification of compound can be achieved by retention time and absorption spectrum.
