This was aim to study the changes of components by different parts and maturity of tomato. Tomato include the green pigment chlorophyll, the yellow pigment -carotene. the red pigment lycopene and the other component. These colors of tomatoes are reported to have important functional roles to promote health in human. The main objective of this study was to define changes in the content of the four tomato maturation that is ascorbic acid, chlorophyll, carotene, lycopene. A ascorbic acid contents of tomato fruits was the highest at 50th day. Chlorophyll contents of tomatoes fruits was the highest at 10th days after flowering. a-carotene contained low-quantity while all growth period. b-carotene contained the highest at 50th days after flowering, 1036.97mg. Lycopene contained the highest at 50th days after flowering, 5800mg.

This was aim to study the changes of components by different parts and maturity of tomato. We found that orally fed tomatine which induced a significant reduction in cholesterol in hamster in contrast to potato glycoalkaloids, the safety of tomatine was supported by our observation that pickled green tomatoes consumed widely in many countries has a high tomatine content. The tomatoes harvested during the first stage(10 days after flowering) contained tomatine 6333.49 ㎍ per 100 g and dehydrotomatine and α-tomatine in a ratio of about 1:13.8. The tomatine content then decreased by about 85% during stage 2(20 days after flowering) an dehydrotomatine contene dropped to a value near zero during stage 3, 4. It then the tomatine content dropped to a value near zero during the final stage(50 days after flowering). With respect to health benefits at all stages of maturity, unripe tomato contain chlorophyll and α-tomatine should consumed.

한국산 재배종 감자의 기관, 품종, 부위, 중량별 Glycoalkaloid의 변화

The concentration of potato(S0lanum tuberasum L.) glycoakaloids(PGA) (i.e., a-chaconine and α- solanine) in Korean cultivated potato pbnt, and in the different varieties, parts and t&&~ of the potato tubes, were clewmud ky highpedormance llqwd chrornatopphy(l-PLC). The hghest concentrations of PGA in potato plants were found in the roots, fdfaued by the stems and leaves. A hge quantity of PGA existed in the periderm of Adantic potatoes, whereas Irish W a contained the lowest amount in five culthated potato tubers. M cobbler potatoes were divided into three parts and the PGA content in each partwasdetennined. Ituasfound that both of the end parts of the potatoes contained higher PGA than the middle part. The FGA contents in four different sizes of potatoes increased toward the smaller size. The significantly tugh lewd of PGA was contained in the smallest size potato tubers, which have been used widely for Korean cooking.
