摘要

The distribution of the flavanones naringin and neohesperidin has been analyzed during the development of the leaves, flower buds, and fruits of Citrus aurantium. These flavonoids are at maximum concentration in the organs studied during the logarithmic phase of growth, gradually decreasing until the organs reach maximum development. However, this decrease in the naringin and neohesperidin concentration in leaves, flower buds, and fruits is due to a dilution of the flavonoids caused by cell growth, because total content per organ continues to increase. The levels of neohesperidin are always greater than those of naringin, although the ratio between the relative concentrations is different in the three organs studied. Leaves have the highest ratios, varying between 8.83 and 5.18, followed by flowers (3.15-1.85), and fruits (2.23-1.02). These observations suggest different relationships between the respective enzymic activities in their biosynthetic pathway.
