Abstract

|
The purpose of this study was to evaluate selected functional compounds and biological activities of 11 different pepper cultivars grown in rain-shelter and field. The selected compounds were capsaicinoids, polyphenolic and vitamin C. Antioxidant activities were measured by ABTS radical scavenging activity, reducing power and metal chelating effect. Antiproliferative activity was assessed by the measurement of the inhibition of HCT116, MCF 7 and NCI-H460 cancer cell proliferation. The contents of capsaicin, dihydrocapsaicin, polyphenolics and vitamin C from 11 cultivars grown in field were 0.0～268.3 ㎎/100 g, 0～55.1 ㎎/100 g, 635～878 ㎎/100 g and 4.1～8.2 ㎎/g, respectively. There were significant differences in the content of selected compounds among the cultivars, although no significant difference in rain-shelter and field was detected. Similar to the results from the selected compounds, there was no difference in antioxidant and antiproliferative activities between rain-shelter and field. This research provides basic information on functional compounds and biological activity of cultivation methods and pepper cultivars.
