Caffeoylquinic acids, found in many plant species, exhibit various biological and pharmacological activities. The stability of 3- and 4-O-caffeoylquinic acid decreases with increasing solution alkalinity, with 3-O-caffeoylquinic acid being more stable. Ultrasound facilitates the degradation and isomerization of these compounds.
Caffeoylquinic acids are existed in many plant species with various biological and pharmacological activities. 3O-caffeoylquinic acid and 4-O-caffeoylquinic acid are two isomers of caffeoylquinic acids, which may be degraded and transformed to their isomers in processing. The present paper found that the stability of 3- and 4-Ocaffeoylquinic acid had decreased with the increasing solution alkalinity. 3-O-caffeoylquinic acid was more stable than 4-O-caffeoylquinic acid at the same condition. During degradation, 3- and 4-O-caffeoylquinic acid were partially converted to their isomers. Additionally, ultrasonic effects on the degradation and isomerization of 3- and 4-O-caffeoylquinic acid at different pH were studied. Ultrasound facilitated the degradation and isomerization of these compounds. The degradation kinetics were described by the Weibull equation. The protective effect of ascorbic acid and epigallocatechin gallate were also explored. Ascorbic acid and epigallocatechin gallate could alleviate the degradation of 3- and 4-O-caffeoylquinic acid under certain conditions.
