Characterization and Quantification of Capsaicinoids and Phenolic Compounds in Two Types of Chili Olive Oils, Using HPLC/MS

Abstract

Chili olive oil is a popular addition to various foods in many countries. In a detailed study, the content of phenols and capsaicinoids in chili olive oil was determined using chili flakes and whole chilies. A total of 99.8% of the phenols in chili olive oil were secoiridoids, with elenolic acid, oleuropein aglycones, and ligostride aglycones being the most abundant. Chili olive oil with chili flakes contained higher levels of capsaicinoids (+21.6%) compared to whole chili olive oil. Capsaicin and dihydrocapsaicin accounted for about 95% of all capsaicinoids in the chili olive oil. The extraction rate of dry “Cayenne” chili was 7.1% in whole chili olive oil and 9% in chili olive oil with flakes, confirming that chili flakes are better extracted in olive oil. With the determination of 29 individual phenols and five individual capsaicinoids, the study provided a detailed insight into the secondary metabolites of chili olive oil and confirmed that it is a health source.

Biochemical and Yield Component of Hybrid Chili (Capsicum annuum L.) Resulting from Full Diallel Crosses

“…The results of this study (Table 5) showed that parent and hybrid chilies contain polyphenol compounds and were grown in a controlled environment in a greenhouse. Polyphenol contents in peppers were been reported in other studies [14,38], which indicated that the potential for polyphenols in hybrids is more significant than in this study. It was reported in previous studies that there is a correlation between capsaicin and polyphenol content [37].…”

“…Chili has a major compound, namely, capsaicin, that makes it spicy [7]. Recent research reports that chili peppers have other functional compounds including: total phenolic content [11], carotenoids [12], terpenoids [13], total flavonoids [14], antioxidant activity [15], and α-glucosidase inhibitory (AGI) activities [16]. α-glucosidase inhibition has an important role in helping patients with type 2 diabetes mellitus [17].…”
