Carotenoid contents in the fruits of a Korean red pepper (Capsicum annum var. subicho) were investigated at different ripening stages such as green, first and second colour break, and red. The individual carotenoids were separated as capsanthin, lutein, zeaxanthin, β-cryptoxanthin, a-carotene, β- carotene and lycopene by reverse-phase HPLC and identified with their authentic standards. The red mature fruits had the highest total carotenoid content (1177.5 mg·kg-1), while the green fruits had low levels (149.9 mg·kg-1). Massive increases in capsanthin, zeaxanthin, and β-carotene, and decreases in lutein and a-carotene were observed during maturation. Immature and mature seeds and placenta were also examined. The seeds had low carotenoid contents, regardless of maturity but the placenta underwent a massive increase in carotenoid levels upon maturation (from 73.1 to 980.3 mg·kg-1) due to elevations in all carotenoids measured, particularly capsanthin and ß-carotene. Unusually, the placenta contained 41.2 mg·kg-1 lycopene whereas other tissues did not express lycopene at all. Examination of other pepper plant tissues revealed very high carotenoid levels in the leaves (2316.4 mg·kg-1).

한국에서 재배되고 있는 고추(수비초) 과실을 성숙단계별 및 부위별로 채취하여 카로티노이드(capsanthin, lutein, zeaxanthin, β-cryptoxanthin, α-carotene, β-carotene and lycopene)의 함량변화를 관찰하였다. 풋고추에서 붉은 고추 단계까지 4단계로 채취된 시료를 사용하였으며 역상칼럼을 장착한 HPLC를 활용하여 정량한 결과 풋고추(149.9 mg·kg-1)에서 붉은고추 (1177.5 mg·kg-1)로 이동 할수록 총 카로티노이드 함량의 급격한 증가를 확인하였으며 lutein과 α-carotene은 오히려 감소하는 경향을 나타냈다. 고추의 종자에서는 성숙단계와 상관없이 낮은 카로티노이드의 함량을 나타냈으나 태좌부에서는 73.1에서 980.3 mg·kg-1으로 높아지는 경향을 나타냈는데 이는 주로 capsanthin과 β-carotene의 함량 증가 때문인 것으로 확인되었다. 꽃과 줄기보다는 잎에서 높은 카로티노이드 함량을 나타냈으며, 특히 lutein은 다른 카로티노이드 성분보다도 꽃, 줄기, 잎에 있어서 각각 56.4, 538.2 및 1538.1 mg·kg-1의 순으로 가장 높은 비중을 나타냈다.
