摘 要 应用火焰原子吸收光谱法对惠安余甘子不同品种、不同器官中的Fe、Zn、Cu、Mn、Ni 5种微量元素的含量进行测定、分析与比较。结果表明:Fe、Zn、Cu、Mn在余甘子各器官中均有一定的分布,其在茎中的含量一般都高于其他器官,而Ni元素在粉甘各器官中仅在幼叶和果核中有检出;野生资源与栽培品种间Fe、Zn、Cu、Mn的含量存在着一定的相似性。

Abstract In order to utilize the medicinal value of Phyllanthus emblica, the contents of five trace elements about Fe, Zn, Cu, Mn, Ni were measured by the method of flame atomic absorption spectrometry (FAAS) in different species, different organs of Phyllanthus emblica L. in hui'an. The results showed that Fe, Zn, Cu, Mn existed in all the organs of the plant. In the stem there usual contain more Fe, Zn, Cu, Mn than any other organs. But Ni element were only determined out a little in immature leaf and fruit in fengan. Also we can find that there are almost the same among some wild resources and cultivars.

余甘(Phyllanthus emblica L.)又名余甘子、油甘子、望果等,为大戟科(Euphorbiaceae)叶下珠属(Phyllanthus)植物,是南方亚热带重要的特产果树,主要分布在福建、广东、云南等省(区);余甘果实营养价值丰富,具有清热解毒、利咽化痰、生津止咳、抗衰老、抗癌等多种保健和药用功效[1-3],深受消费者喜爱。余甘子维生素C含量很高,每100 g果肉中含维生素C平均251.9 mg,可与猕猴桃相媲美[4-5]。余甘子具有极其丰富的人体必需的8种氨基酸和其它12种氨基酸,还含有多种微量元素及可提供人体合成许多不同有机物的高比例的还原单糖[6-7]。
微量元素对人体健康的功效已有大量报道[8],其生物功能主要有酶激活作用、宏量元素运载作用、核酸代谢作用和参与激素作用等。微量元素在人体的健康防病治病和延年益寿中均具有重要意义。因此对余甘子各品种、各器官的微量元素含量进行分析,对进一步开发利用余甘子药用成分,促进本市余甘子生产,发展区域经济具有重要意义。
