不同产地长柄扁桃种仁成分分析

采用GC-MS、AAS、HPLC等方法对选自陕西神木、内蒙古包头、内蒙古阿拉善盟、河北承德4个不同产地的长柄扁桃种仁的一般成分(粗脂肪、粗蛋白、水分、灰分、总糖、总膳食纤维)、氨基酸、微量元素、脂肪酸及苦杏仁苷含量等进行分析。研究表明,不同产地长柄扁桃种仁各组分含量有一定差别,但均富含粗脂肪(416~478g/kg)和粗蛋白(206~286g/kg);种仁中氨基酸种类齐全,含量丰富;均含Ca、Mg、P、Fe、K等9种对人体有益的矿质元素,未检出Pb、Cd、Hg、As等元素;长柄扁桃油中不饱和脂肪酸含量在96.8%以上,以油酸和亚油酸主;苦杏仁苷含量在3%左右。从测定结果来看,长柄扁桃种仁可以作为开发食用油、蛋白粉以及苦杏仁苷的原材料,具有较好的经济价值,适宜于广大北方荒漠地区推广种植。

Composition Analysis of Amygdalus pedunculata Pall.Seed from Different Regions

GC-MS,AAS and HPLC were selected to analyze the content of general component(crude fat,crude protein,ash,moisture,total sugar,toal dietary fiber),amino acids,trace elements,fatty acids and amygdalin in the Amygdalus pedunculata Pall.seeds,which came from four regions:Shenmu,Shaanxi;Baotou,Inner Mongolia;Alashan Inner Mongolia and Chengde,Hebei.The results showed that the content of the seeds from different areas had some difference,but there were some similarities as follows:The seeds were rich in crude fat(416-478 g/kg) and crude protein(206-286 g/kg);The amino acids in the seeds were abundant and complete in varity;All the seeds contained 9 mineral elements(K,Mg,Ca,P,Na,Fe,Zn,etc.) that were necessary for the human health;Elements like Pb,Cd,Hg,As were not found;The content of unsaturated fatty acid,most of which were oleic acid and linoleic acid,in the seed oil was over 96.8%;The content of amygdalin was 3%.The results showed that the A.pedunculata Pall.seeds can be used to produce edible oil,protein and amygdalin.That is to say,it had great economic value and it was fit to plant in the desert north of our country.
