摘要：

A high-pressure liquid chromatographic (LC) procedure for the quantitation of sweet potato phenolics was developed. After extraction and sample cleanup, analyses were performed with a reverse-phase C-18 column using a methanol-sodium phosphate buffer system (pH 3.0). Individual phenolics were quantitated with a fixed wavelength detector operating at 313 nm. Only caffeoylquinic acid esters were identified. Chlorogenic acid and isochlorogenic acid were the most abundant components comprising 80% or more of the total. The phenolic content ranged from 14 to 51 mg/100-g sample (fresh weight) depending upon the cultivar. © 1979, American Chemical Society. All rights reserved.
