In another study, when astaxanthin was compared to the three other carotenoids (beta-carotene,
capsanthin, and bixin), astaxanthin was found to be the most active in preventing the reproduction of human leukemic cells.
Oleoresins contain a significant amount of esters of capsorubin,
capsanthin, cryptoxanthin, zeaxanthin, and other carotenoids [70, 71], used in foodstuff and cosmetics, and serve as a source of the pungent component capsaicin for pharmaceutical products [72, 73] or self-defense weaponry [74].
The free radicals produced by irradiation led to chemical reactions, such as ferrous ions in heme oxidized to ferric iron, and
capsanthin in pepper powder was decomposed into other chemicals.
Capsanthin, capsorubin, cryptoxanthin, and zeaxanthin are the major carotenoids present in Capsicum (NADEEM et al., 2011).
Chilies have a strong spicy taste that comes to them from the active alkaloid compounds: capsaicin,
capsanthin and capsorubin.
Capsanthin, which is presumed to be the major active constituent of red pepper, has an acidic hydroxyl group on its aromatic ring which could be neutralized by alkali thereby increasing its release (Liu, 2009).
If some varieties of chillies are famous for red color because of the pigment '
capsanthin,' others are known for biting pungency.
The required egg colour density is controlled both by the dietary concentration of yellow (lutein, zeaksantin and apo-ester) and red pigmentors (cantaxhantin, citranaxhantin and
capsanthin) (Chen and Yang, 1992; Lai et al., 1996).
The red peppers contained a higher level of beta-carotene,
capsanthin, quercetin, and luteolin.
