Antioxidant Activity of a New Capsaicin Derivative from Capsicum annuum 

 -  Journal of Natural Products, 66(8), p.1094-1096, 2003 .
<br/><br/> A new capsaicin derivative, 6¢¢,7¢¢-dihydro-5¢,5¢¢¢-dicapsaicin (1), and a known capsaicin metabolite, ö-hydroxycapsaicin (2),1 were isolated from the fruit of Capsicum annuum. Their structures were established on the basis of spectroscopic evidence. Compound 1 showed almost the same antioxidant activity as capsaicin, but did not have a pungent taste. }
