Description General description Dihydrocapsaicin belongs to the capsaicinoid group of compounds which are responsible for the pungency of capsicum fruits. Application Dihydrocapsaicin has been used as a reference standard for the identification of dihydrocapsaicin in blood and tissue samples by high performance liquid chromatography (HPLC) combined with tandem mass spectrometry (MS) and in tomato-based salsas by enzyme immunoassay (EIA) and LC with fluorescent detection. It may be used as a reference standard for the determination of dihydrocapsaicin in Capsicum fruit samples by HPLC equipped with a Surveyor photodiode array (PDA) detector and in rat plasma by HPLC-triple quadrupole MS with electrospray ionization (ESI) in selected reaction monitoring (SRM) mode. Biochem/physiol Actions VR1 vanilloid receptor agonist. Linkage Capsaicin analog.
