在空气、空气+10ppm C2 H4或10%O2 + 10%CO2受控气氛（CA）中储存的欧芹叶中监测色素。叶绿素a和B，用HPLC测定，急剧下降，在叶片中举行的空气或空气+ 10 ppm C2 H4。在10%O_2和10%CO_2的CA中，叶片的下降较小。叶绿素a的氧化产物，10-羟基叶绿素a，没有积累和叶绿素积累最低限度。叶黄素减少，但新的色素，怀疑是酯化叶黄素，形成与叶变黄。无论是叶绿素降解或叶黄素产品的途径被C2 H4或CA改变。
Pigments were monitored in parsley leaves stored in air, air + 10 ppm C2H4, or 10% O2 + 10% CO2 controlled atmosphere (CA). Chlorophylls a and b, as determined with HPLC, decreased sharply in leaves held in air or air + 10 ppm C2H4. The decrease was less in leaves held in 10% O2 and 10% CO2 CA. The oxidized product of chlorophyll a, 10-hydroxychlorophyll a, did not accumulate and chlorophyllide accumulated minimally. Xanthophylls decreased but new pigments, suspected to be esterified xanthophylls, formed with yellowing of leaves. Neither the pathway of Chl degradation or xanthophyll products were altered by C2H4 or CA.
