Capsaicinoids quantification in chili peppers cultivated in the state of Yucatan, Mexico

Capsaicinoids content and proximate composition of Mexican chili peppers (Capsicumspp.) cultivated in the State of Chihuahua

“…In these varieties, capsaicin concentration ranged between 22 mg/kg and 66.87 mg/kg, and dihydrocapsaicin concentration between 36 mg/kg and 77.12 mg/kg. These results support the findings by Cisneros-Pineda et al (2007), and Garces-Claver et al (2006) who found that some C. annuum cultivars contain higher concentrations of dihydrocapsaicin than the amounts found in C. chinense (Habanero). Ancho pepper showed a low capsaicinoids' concentration with a similar content of capsaicin and dihydrocapsaicin (42.82 mg/kg and 42.19 mg/kg, respectively).…”

“…These findings validate research by Cisneros-Pineda et al (2007) who found that capsaicinoids content is higher in ripe than in unripe peppers. The difference between the two is that Chipotle is smoked ripe (when the fruit reaches its red color) and Meco is smoked unripe (fresh state, or green).…”

“…The capsaicinoids extraction method used in this study was an adaptation of the method reported by Cisneros-Pineda et al (2007) using methanol instead of acetone (Kurian & Starks, 2002;Ornelas-Paz et al, 2010). Dried tissue of solid pepper samples were blended to a fine powder and 0.6 g of powdered chili pepper sample were mixed with 10 mL of methanol high-performance liquid chromatography (HPLC) grade.…”

Computer Aided Design of Molecular Imprinted Polymer for Selective Recognition of Capsaicin

“…It can be understood easily if we see the structure of capsaicin (Fig. 1) on the hydrophilic site that gives contribution to this descriptor [3]. Amine contributes one hydrogen donor atom because it is always available in the side chain of capsaicinoid compounds.…”

“…Present methods for analysis capsaicinoid are gas chromatography [3], reversed-phase highperformance liquid chromatography (HPLC) [4], micellar electrokinetic chromatography (MEKC) [5], HPLC coupled with mass spectrometry [6], and capillary electrophoresis [7]. However, all these methods, sometimes give several problems such as detection limits, very laborious, lengthy analysis, expensive or the requirement of tedious pretreatment.…”
