西红花花瓣中氨基酸与微量元素等成分含量研究

Content of Amino Acids,Trace Elements and Other Components in Petals of Crocus sativus

目的:测定西红花非药用部位花瓣中氨基酸、微量元素和蛋白质的含量,为其综合利用提供参考。方法:采用氨基酸分析仪、电感耦合等离子质谱法(ICP-MS)、凯氏定氮仪分别对西红花花瓣中的16种氨基酸、26种微量元素及蛋白质进行分析研究。结果:西红花非药用部位的花瓣中含有人体所需的6种必需氨基酸(苏氨酸、缬氨酸、异亮氨酸、亮氨酸、苯丙氨酸和赖氨酸)和6种微量元素(铬、铁、钴、铜、钼和锌),含有对人体至关重要的蛋白质,同时未检测到对人体有潜在危害的重金属元素锡和汞。结论:西红花花瓣含有丰富的营养物质,可以进行综合利用,开发其在保健食品领域的应用潜力。

Objective:To determine the content of amino acids,trace elements and proteins in the petals,non-medicinal parts,of Crocus sativus L.,which can provide a scientific basis for its comprehensive utilization.Methods:Sixteen amino acids,twenty-six elements and proteins in C.sativus petals were analyzed with an amino acid analyzer,an inductively coupled plasma-mass spectrometer(ICP-MS)and automatic Kjeldahl apparatus.Results:The C.sativus petals contain 6 kinds of essential amino acids(threonine,valine,isoleucine,leucine,phenylalanine and lysine),6 kinds of essential trace elements(Cr,Fe,Co,Cu,Mo and Zn)and proteins vital to the human body.Moreover,no tin and mercury were detected which were heavy metal elements potentially harmful to human health.Conclusion:The petals of C.sativus are rich in nutrients,which can be comprehensively utilized for its application and research in the field of health food.
