【摘要】：对采集于不同地区的野生黑果枸杞中碳水化合物、蛋白质、脂肪、灰分、氨基酸、脂肪酸等营养成分和花青素、多糖、多酚等生物活性成分及抗氧化活性进行检测和比较分析。结果表明:不同地区野生黑果枸杞碳水化合物、蛋白质、脂肪及灰分含量范围分别为69.55%~77.14%、10.76%~14.72%、3.90%~6.89%和6.63%~10.99%,不同地区间各成分含量有一定的差距。黑果枸杞中氨基酸种类为17种,总量在7.459%~10.514%之间;不饱和脂肪酸含量在73.00%~85.29%之间,其中内蒙古阿拉善右旗阿拉腾敖包黑果枸杞不饱和脂肪酸相对含量最高,达85.29%。黑果枸杞还富含活性成分,花青素平均含量为2.29%,多糖平均含量为5.22%,多酚平均含量为3.94%。内蒙古阿拉善右旗阿拉腾敖包黑果枸杞花青素提取液清除DPPH·和·OH能力均最强,清除率分别为96.61%和54.04%,蒙古国苏木贝尔黑果枸杞花青素提取液还原能力最强(2.94)。因此,不同地区野生黑果枸杞均具有较高的营养价值,且存在一定的地区差异性。
[Abstract]:The contents of carbohydrate, protein, fat, ash, amino acid, fatty acid, anthocyanin, polysaccharide, polyphenol and antioxidant activity in wild black fruit wolfberry were detected and compared. The results showed that the contents of carbohydrate, protein, fat and ash in wild Lycium barbarum were 69.557.14 and 10.767.14, respectively. The contents of carbohydrate, protein, fat and ash were 6.89% and 6.630.99%, respectively. There are 17 kinds of amino acids in black fruit wolfberry, the total amount is between 7.459 and 10.514%, and the content of unsaturated fatty acids is between 73.00 and 85.29%, and the relative content of unsaturated fatty acids of Aateng Aobao black wolfberry in Alashan, Inner Mongolia, is the highest, reaching 85.29%. The average content of anthocyanin, polysaccharide and polyphenol were 2.29, 5.22 and 3.94, respectively. The ability of removing DPPH and OH from Aateng Aobo black fruit and Chinese wolfberry anthocyanin extract was the strongest in Ala Shan right Banner of Inner Mongolia, with clearance rates of 96.61% and 54.04%, respectively. Therefore, wild Chinese wolfberry has high nutritional value and regional differences in different areas.
