摘　　要：为探究枸杞中的褪黑素含量及其积累特征,使用宁夏6个枸杞材料,通过高效液相色谱法测定褪黑素含量,分析枸杞不同器官、果实不同发育期、不同成熟期、不同材料、不同立地条件下的褪黑素含量,并分析土壤理化因子与枸杞不同器官中褪黑素含量间的关系。结果表明,枸杞不同器官中的褪黑素含量存在一定差异,其中褪黑素含量大小通常遵循花>叶>茎>根。在春果青果期与变色期的果实中检测到褪黑素,在黄熟期与红熟期的春果果实中未检测到褪黑素;在秋果不同果实发育时期的果实中均检测到褪黑素,在青果期果实中的褪黑素含量最高,之后随着果实的发育,果实中的褪黑素含量逐渐下降,到果实成熟时又有所上升。宁杞菜1号各器官中的褪黑素含量显著高于宁杞1号,在不同材料的枸杞叶片中,褪黑素含量排序为宁杞菜1号>宁杞7号>黄果枸杞>黑果枸杞>宁杞10号>宁杞1号。在盐分含量高的立地条件下,枸杞各器官中的褪黑素含量显著增加。以上结果表明,枸杞中含有丰富的褪黑素,对于同一枸杞材料而言,各器官中褪黑素含量的排序为花>叶>茎>根,褪黑素含量在果实发育过程中的青果期、变色期较高,秋果中各器官的褪黑素含量大于春果,枸杞在高盐环境中有利于体内褪黑素的积累。To explore the content and accumulation characteristics of melatonin in Lycium barbarum,six Lycium barbarum materials in Ningxia were used,and the content of melatonin was determined by high performance liquid chromatography.The melatonin content in different organs of Lycium barbarum,at different developmental stages of the fruits,at different maturity stages,in different materials and under different site conditions was analyzed.Moreover,the relationship between soil physical and chemical factors and the melatonin content in different organs of Lycium barbarum was analyzed.The results showed that there were some differences in the content of melatonin in different organs of Lycium barbarum,and the content of melatonin usually followed the order of flower > leaf > stem > root.Melatonin was detected in spring fruits at green fruit stage and discoloration stage,and melatonin was not detected in fruits at yellow ripening stage and red ripening stage.Melatonin was detected in autumn fruits at different developmental stages.Melatonin content was highest in fruits at the green fruit stage.Subsequently,as the fruits developed,the melatonin content in the fruits gradually declined,and then increased again when the fruits ripened.The content of melatonin in each organ of Ningqicai No.1 was significantly higher than that of Ningqi No.1.In the leaves of different materials,the melatonin content followed the order of Ningqicai No.1 > Ningqi No.7 > Huangguo wolfberry > Heiguo wolfberry > Ningqi No.10 > Ningqi No.1.Under high-salt conditions,the content of melatonin in each organ of Lycium barbarum increased significantly.The above results indicated that Lycium barbarum was rich in melatonin.For the same Lycium barbarum material,the order of melatonin content in each organ was flower > leaf > stem > root.Melatonin content was higher in the green fruit period and discoloration period during fruit development.The melatonin content of each organ in autumn fruits was higher than that in spring fruits.Lycium barbarum in high salt
