在了解血红素生物合成代谢途径和胆绿素、原卟啉结构的基础上，比较了同一种群（东乡族）蓝壳蛋和褐壳蛋蛋壳色素总量的差异，并分析了2种蛋壳色素中原卟啉和胆绿素含量的相关性。发现东乡青壳蛋和东乡褐壳蛋蛋壳色素总量差异不显著（P = 0.9006），蓝蛋壳中原卟啉和胆绿素含量呈极显著正相关褐壳中原卟啉含量与胆绿素含量呈显著正相关（P <0.05）。这些结果表明，蛋壳原卟啉和蛋壳胆绿素可能来源于共同的前体物质。
Based on the knowledge of the heme biosynthetic and metabolic pathway and the structures of biliverdin and protoporphyrin, experiments were carried out to compare the difference between the total quality of eggshell pigments in blue-shelled eggs and brown-shelled eggs from the same population (Dongxiang, China) and to analyze the correlation between the quantity of protoporphyrin and biliverdin in the 2 kinds of eggshells. It was found that there was no significant difference between the total quantity of eggshell pigments in Dongxiang blue-shelled eggs and Dongxiang brown-shelled eggs (P = 0.9006), and a highly significant positive correlation between the quantity of protoporphyrin and biliverdin in blue eggshells (P < 0.01) and a significant positive correlation between the quantity of protoporphyrin and biliverdin in brown eggshells (P < 0.05). These results suggested that eggshell protoporphyrin and eggshell biliverdin probably derived from common precursor material.
