Quantification of capsaicin by LC–ESI–MS/MS
An LC-ESI-MS/MS method through MRM was developed for the
selective detection and quantification of 1 and 3 at 11.22 and
12.35 min in the extract (Fig. 3). The selectivity and sensitivity of
(MRM) LC-ESI-MS/MS relies on the application of MRM in which
each ionized compound gives a distinct precursor-to-product ion
transition that is diagnostic for the presence of a particular comtR
