A total of 181 compounds were reported for the first time in this fruit, 119 and 163 compounds were identified as headspace volatiles and fruit volatiles, respectively. Ethyl butyrate, ethyl hexanoate, β-caryophyllene and selin-11 -en-4α-ol were the major compounds. Esters (69.5%) and terpenes (60.8%) were the major classes of compounds found in the headspace volatiles and fruit volatiles.

Volatile compounds of capsicum frutescens L. cultivars from Colombia / C. E. Quijano in The journal of essential oil research, Vol. 22 N° 6 (Novembre/Décembre 2010)

One-hundred-seventy-two volatile compounds were identified in the cultivars, representing 30.26 mg/kg, 22.36 mg/kg and 68.26 mg/kg for Cesari amarillo, Cesari morado and Pajarito cultivars, respectively. Isohexyl isohexanoate, isohexyl isovalerate and isohexyl 2-methylbutyrate were the major compounds in Cesari amarillo and Cesari morado; while in the Pajarito cultivar the majors were isohexyl isovalerate and hexyl isovalerate. Cesari amarillo and Cesari morado have many similarities among them in comparison with the Pajarito cultivar, not only in the total amount of volatiles, but also in the individual distribution of major compounds.
