测定了脐橙果实生长和成熟过程中柠檬酸a环内酯（LARL）和柠檬酸17- β - d -葡萄糖吡喃苷（LG）的含量。LARL含量（克/果）在6 ~ 8月急剧上升，8月底达到最大值，此后逐渐下降。LG于9月开始在果肉部分出现，1个月后在果皮部分出现。其含量从9月到11月急剧增加，此后缓慢增加。LARL的减少和LG含量的增加同时发生在果实生长和成熟后期，表明LG是LARL的代谢物。总柠檬苦素（LARL + LG）含量在11月底前持续增加，此后基本保持不变。这表明LARL的生物合成及其向LG的进一步转化似乎在果实中持续到11月底。
The amounts of limonoate A-ring lactone (LARL) and limonin 17-beta-D-glucopyranoside (LG) in navel oranges were measured during fruit growth and maturation. The LARL content (grams/fruit) increased sharply from June to August, reached a maximal level at the end of August, and then decreased gradually thereafter. LG began to appear in the flesh portion in September and in the peel 1 month later. Its content increased sharply from September to November and then slowly thereafter. The decrease in LARL and the increase in LG content occurred simultaneously at late stages of fruit growth and maturation, suggesting that LG is a metabolite of LARL. The amounts of total limonin (LARL + LG) continued to increase until the end of November and then remained fairly constant thereafter. This showed that the biosynthesis of LARL and its further conversion to LG appeared to continue in the fruit until the end of November.
