本研究以省產柑桔類 (椪柑、柳橙、海梨、桶柑) 果實為原料，探討採收期間果實各部位橘皮苷含量之變化。由研究結果得知橘皮苷於果實各部位均有存在，其中以中果皮含量最多 (1.0-3.05g/100g 鮮重 )，而種子含量最少 (0.006-0.044g/100g 鮮重 )。 果實各部位之橘皮苷總量均有隨果實成熟度之增加而降低的趨勢。在不同品種之比較中，椪柑及柳橙之橘皮苷含量明顯高於海梨及桶柑。

The change in hesperidin content in each part of four citrus fruits (Liu-cheng, Ponkan, Tankan and Hai-li) produced in Taiwan during their respective harvest periods was investigated. Each part of these citrus fruits contained hesperidin, with albedo having the highest amount of hesperidin (1.0-3.05g/100 gfresh wt.) and seed containing the least (0.006-0.044 g/100g feesh wt.). The total content of hesperidin in each part of these citrus fruits decreased with increasing maturity of the fruit. The hesperidin content in Liu-cheng and ponkan was significantly higher than that of Tankan and Hai-li.
