Abstract

Phlorin (3,5-dihydroxyphenyl beta-D-glucopyranoside), an orange peel marker, has been searched in 45 species and varieties of Citrus. The phlorin content was determined by high-pressure liquid chromatography in juices and aqueous peel extracts of these different fruits. The phlorin content in C. reticulata peel extract varies from 0 to 1012 mg L(-)(1) with a mean of 162 mg L(-)(1). On the contrary, phlorin was not found in mandarin and clementine juices except for mandarin "Commune" and "Beauty" (33 and 30 mg L(-)(1), respectively). In the 14 species of oranges and varieties, phlorin was detected in juices and peel extracts with a mean of 22 and 492 mg L(-)(1), respectively, while for grapefruits, means were 108 mg L(-)(1) in juices and 982 mg L(-)(1) for peel extracts. Tangors and tangelos which are hybrids (C. reticulata x C. sinensis and C. reticulata x C. paradisi, respectively) are characterized by the systematic presence of phlorin in peels (mean: 406 and 659 mg L(-)(1), respectively) while in juices its presence could be variable (0-73 mg L(-)(1)). These heterogeneity and values may be explained by the genetic variability of these hybrids and the phlorin content of their parentage group.

摘要

橙皮苷（3,5 - 二羟基苯基β - D - 吡喃葡萄糖苷）是一种橙皮标记物，已在45种柑橘属物种和品种中进行了研究。通过高压液相色谱法测定了这些不同水果的果汁和果皮水提取物中的橙皮苷含量。温州蜜柑果皮提取物中的橙皮苷含量在0至1012 mg L⁻¹之间，平均为162 mg L⁻¹。相反，除了“Commune”和“Beauty”两种温州蜜柑（分别为33和30 mg L⁻¹）外，在宽皮柑橘汁中未发现橙皮苷。在14种橙子品种中，果汁和果皮提取物中均检测到了橙皮苷，其平均含量分别为22和492 mg L⁻¹，而对于葡萄柚，果汁中的平均含量为108 mg L⁻¹，果皮提取物中的平均含量为982 mg L⁻¹。橘橙和橘柚分别是（温州蜜柑×甜橙和温州蜜柑×葡萄柚）的杂交品种，其特点是果皮中系统地存在橙皮苷（平均含量分别为406和659 mg L⁻¹），而果汁中的含量可能有所不同（0 - 73 mg L⁻¹）。这些异质性和数值可能由这些杂交品种的遗传变异性及其亲本群体的橙皮苷含量来解释。
