Y. Goda et al., IDENTIFICATION OF MONOESTERIFIED CAPSANTHIN IN PAPRIKA (CAPSICUM-ANNUUM) - THE NATURE OF ESTERIFICATION OF CAPSANTHIN, Chemical and Pharmaceutical Bulletin, 43(7), 1995, pp. 1248-1250
Capsanthin esters were separated from paprika (Capsicum annuum) oleore
sin, and their structures were determined without saponification. The
major monoesterified capsanthin was identified as 3'-O-myristoylcapsan
thin. 3-O-Esterified capsanthins were not detected, although 3,3'-O-di
esterified capsanthins with saturated fatty acids were isolated. The r
esults suggest that the rate in esterification of fatty acid to the hy
droxyl group on the cyclopentane ring of capsanthin is different from
that on the cyclohexene ring.
