摘　　要：为研究空间分布差异性对新疆沙棘资源果实品质及营养成分的影响。以5个县的‘深秋红’‘无刺丰’‘状圆黄’沙棘品种为供试样本,并对供试样本的可溶性固形物、蛋白质、氨基酸、总糖、总酸、维生素C、微量元素、总黄酮、脂肪酸、花青素、β-胡萝卜素、番茄红素含量测定,后进行主成分分析并计算综合得分。13个供试沙棘样品果实中各营养及药用成分均存在不同程度的差异性。青河县沙棘果实综合测试指标比布尔津县综合高出0.93~5.54倍,比哈巴河县综合高出0.90~4.49倍,比乌什县综合高出0.99~13.67倍,比阿合奇县综合高出1.10~4.98倍。青河县沙棘品种‘状圆黄’果实各项品质指标表现最优,综合得分为6.04分;且青河县沙棘资源整体综合得分最高,平均为3.54分。青河县更适宜沙棘的生长发育,种植的沙棘果实品质更为优异,13个供试沙棘样品中青河县‘状圆黄’果实品质最佳。Seabuckthorn fruit is one of the most nutritious and medicinal berries.This study aims to analyze the fruit quality and medicinal components in the Xinjiang seabuckthorn under spatial distribution differences.The test bases were taken as the seabuckthorn plantations in five counties of the main seabuckthorn resource distribution areas in Xinjiang(Qinghe county in Altay Prefecture,Buerjin county in Altay Prefecture,Habahe county in Altay Prefecture,Wushi county in Aksu Prefecture,and Aheqi county in Kizilsu Kirgiz Autonomous Prefecture).Three seabuckthorn varieties of'Shenqiuhong','Wucifeng'and'Zhuangyuanhuang'were used as test samples.Some indicators of mature seabuckthorn fruits were determined,such as the basic factors,trace elements,functional quality,and medicinal components.Data support was also provided to optimize the planting structure of seabuckthorn resources,in order to promote the modernization,large scale and standardization in industrial production.Specifically,the sampling was carried out on the plantations in the distribution area of seabuckthorn.Three planting plots were selected for each variety,i.e.,nine planting plots were from each county(only three planting plots were selected in Wushi county,because only distributed'late autumn red').The'five-point'was captured on the fruit from each sample collection site.A total of 15 samples were collected from each variety,and a total of 195 fruit samples were collected.The samples were firstly placed in an insulated foam box with an ice bag and transported back to the laboratory.The samples were then frozen in a refrigerator at−15℃.A systematic measurement was performed on the fruit quality and medicinal component indexes(soluble solids,protein,total sugar,total acid,vitamin C,trace elements,total flavonoids,anthocyanins,β-carotene,lycopene,and amino acids,fatty acids).A comprehensive evaluation was then made to calculate the total score.The results showed that there were various degrees of the differences in the contents of various nutrients and
