本実験では12種 (うち, 2種は2系統) の市販野菜を有色と淡色に大別し, クロロフィル, カロテノイド, ビタミンE, ビタミンCおよび無機質の含有量を分析して次の結果を得た.<BR>クロロフィルはニソジンを除くすべてからかなりのフェオフィチンの含有が認められ, これらは生長期から収穫期に至り, 相当量のクロロフィルが分解されたことを示す. クロロフィルの分解程度の測定が困難であり, また, 測定値の明確な基準がなく, 有色, 淡色の区分けには成り難いことが明らかとなった.<BR>以上の結果, β-カロテン当量から換算されるレチノール当量を有色, 淡色に区別する根拠になり得ることが分かった. なお, リコペンはトマト, ニンジンより検出され赤色を呈するが, レチノール当量にはならない.また, ピーマンより検出されたカプソルビン, カプサンチンも橙赤色であるが, レチノール当量にならない.<BR>ビタミンEはシソ, シュンギク, ニラ, パセリおよびホウレンソウなど有色の葉菜類に多い. トマト, ピーマン (果菜類) に少ないことがわかった. ビタミンCは未熟果の緑色の時期から蓄積されたものがかなりの含有量になったものと推定された.すなわち, クロロフィルの減少に伴いエンジオール基をもつビタミンCが増大することが明らかとなった.<BR>無機質としては, K, Caが他より桁違いに多く平均Kでは80%, Caでは18%と相対的に有色のものに多い. これについで, Mgが多く, 全般的に無機質含量は淡色よりも有色 (緑黄色) 野菜に多かった.

This research examined the contents and compositions of chlorophylls, carotenoidsvitamin E, vitamin C and metals in 12 species of vegetables that included six species ofdeep-colored vegetables and six species of light-colored vegetables.<BR>Concerning the chlorophyll contents, perilla and spinach belonging to the deep-coloredvegetables contained a large amount of chlorophyll (115-175mg/100g).On the otherhand, only a small amount of chlorophylls were found in cucumber, cabbage, snap beanetc.belonging to the light-colored vegetables.Moreover, pheophytin was detected in allthe examined vegetables except for carrot.<BR>Concerning the carotenoids, perilla and spinach, belonging to the deep-colored vegetables, also contained a large amount of β-carotene (1, 550-795IU/100g). On the otherhand, small amount of β-carotene were found in cucumber, cabbage, snap bean, tomatoand sweet pepper. Furthermore, lycopene, β-carotene, and phytofuluene were detectedin tomato and carrot. Moreover, in addition to ζ-carotene, α-carotene was detected inperilla, snap bean and carrot.About xanthophylls;capsanthin, capsorubin and luteinepoxidewere identified in sweet pepper, while violaxanthin, lutein, lutein epoxide andneoxanthin were detected in the other investigated vegetables.Furthermore, the α-and β-cryptoxanthins were detected in tomato and sweet pepper. The retinol potency calculated from the β-carotene content was found to be greater than 1, 000IU/100g inperilla, garland chrysanthemum, Chinese chive, carrot and parsley belonging to the deep-colored vegetables. On the other hand, the retinol potency in cabbage, cucumber andcelery was very low (80-5IU/100g).<BR>Concerning the vitamin E contents, it was found that perilla, garland chrysanthemum, leek, parsley and spinach, belonging to the deep-colored leaf vegetables contained largeamounts (4.6-2.2mg) of vitamin E, while tomato and sweet pepper, belonging to thefruit vegetables contained relatively small amounts (0.9-0.7mg) of vitamin E.Thedeep-colored vegetables such as garland chrysanthemum, leek, parsley and spinach contained82-36mg of vitamin C.The red fruit vegetables, tomato and sweet pepper alsocontained vitamin C which seemed to accumulate during the green color stage.<BR>Concerning metals, potassium and calcium were found to be the major component followedby magnesium in all the investigated vegetables.The deep-colored vegetablescontained relatively large amounts of the metals described above.Sodium was detectedas a relatively major component in garland chrysanthemum, spinach, celery and cabbage. Iron (Fe) was detected as a small component and copper (Cu) and zinc (Zn) were detected as very small components in all the investigated vegetables.
