| 摘 要： | 采用高效液相色谱法分析鞣花酸（ellagic acid，EA）、齐墩果酸（oleanolic acid，OA）和熊果酸（ursolicacid，UA）在枣庄大青皮石榴不同部位的分布规律。结果显示，EA含量：花瓣（5.78 mg/g）＞花托（5.22 mg/g）＞花蕊（4.93 mg/g）＞叶片（3.67 mg/g）＞果皮（2.12 mg/g）；UA含量：花蕊（6.22 mg/g）＞花瓣（5.91 mg/g）＞叶片（2.90 mg/g）＞花托（1.06 mg/g）＞果皮（0.33 mg/g）；OA含量：花瓣（6.62 mg/g）＞花蕊（4.02 mg/g）＞叶片（1.41 mg/g）＞花托（0.79 mg/g）＞果皮（0.28 mg/g）。表明石榴的叶、果皮和花均可作为制取EA和三萜类物质的原料，2 类物质的含量在石榴花中最高，更具开发利用前景。

| Abstract: | The distribution of ellagic acid (EA), oleanolic acid (OA) and ursolic acid (UA) in the petals, receptacle stamens,
leaves and peel of ‘Daqingpi’ pomegranate in Zaozhuang of Shandong province was studied using high performance liquid
chromatography (HPLC). The results showed that the content of EA was in the decreasing order of petals (5.78 mg/g) >
receptacle (5.22 mg/g) > stamens (4.93 mg/g) > leaves (3.67 mg/g) > peel (2.12 mg/g); for UA, the decreasing order was
stamens (6.22 mg/g) > petals (5.91 mg/g) > leaves (2.90 mg/g) > receptacle (1.06 mg/g) > peel (0.33 mg/g); and for OA,
the decreasing order was petals (6.62 mg/g) > stamens (4.02 mg/g) > leaves (1.41 mg/g) > receptacle (0.79 mg/g) > peel
(0.28 mg/g). It is suggested that leaves, peel and flowers of pomegranate may be used as raw materials for extracting EA and
triterpene. Especially, the flowers have better prospects for development and utilization. |
