以甘肃民勤野生黑果枸杞为材料，测定了其水分、灰分、脂肪、蛋白质、总黄酮、多酚、总花色苷和氨基酸等成分含量。结果表明，民勤野生黑果枸杞果实含水分795 g/kg、灰分57.254 g/kg、脂肪0.490 g/kg、蛋白质0.084 83 g/kg、总黄酮25.90 mg/g、总多酚27.51 mg/g、总花色苷1.27 mg/g。氨基酸总量为21.33 mg/g，其中必需氨基酸有7种，占总氨基酸的27.1%；药效氨基酸9种，占总氨基酸的65.8%。药用氨基酸谷氨酸、天门冬氨酸、精氨酸含量较高，具有较高的药用价值。

Taking the wild Lycium ruthenicum from Minqin of Gansu Province as the material， the nutrient contents of water， ash， fat， protein， total axunge， total flavonoids， polyphenol， total anthocyanins and amino acid were determined. The results showed that the cotent of wate was 795 g/kg， ash was 57.254 g/g， was fat 0.490 g/kg， protein was 0.084 83 g/kg， total flavonoids was 25.90 mg/g， total polyphenol was 27.51 mg/g， total anthocyanin was 1.27 mg/g. The total amino acids were 21.33 mg/g， among which seven kinds of essential amino acids accounted for 27.1% of the total amino acids. There were 9 kinds of pharmacodynamic amino acids， accounting for 65.8% of the total amino acids. The content of glutamic acid， aspartic acid and arginine in the pharmacodynamic amino acid is higher， which has higher medicinal value.
