中文摘要:

      目的 分析不同产地的黑果枸杞(Lycium ruthenicum Murr.)的营养成分及生药学特征研究。 方法 分别选择新疆、宁夏、甘肃、青海4种不同产地黑果枸杞, 按照国家标准对其水分、灰分、总蛋白、总脂肪、氨基酸及微量元素的含量进行测定、对其粉末进行性状、水试、显微和理化鉴定。结果 不同产地黑果枸杞水分、灰分、铅含量无显著性差异(P>0.05), 测定的其他金属元素有显著性差异(P<0.05)。新疆产地钙、锌含量最高分别为1758、14.3 mg, 宁夏产地铁含量最高为240 mg, 青海产地镁含量最高为1790 mg。除丙氨酸以外, 其余氨基酸无显著性差异(P>0.05), 性状和显微结构有一定的差异, 显微结构上差异主要表现在石细胞和果皮表皮细胞上, 但其Rf值无显著性差异(P>0.05)。结论 4种黑果枸杞在基本组成、金属元素含量和性状都有所不同, 为进一步研究黑果枸杞的保健功能提供实验基础和理论依据。

英文摘要:

      Objective To analyze the nutrition components and pharmacological characteristics of Lycium ruthenicum Murr. from different habitats. Methods The Lycium ruthenicum Murr. of 4 different producing areas in Xinjiang, Ningxia, Gansu and Qinghai were selected. According to the national standard, the content of water, ash, total protein, total fat, amino acid and trace elements of Lycium ruthenicum Murr. was determined, and the powder was subjected to traits, water test, microscopic and physical and chemical identification. Results There was no significant difference in water, ash and lead content between the black sorghum from different habitats (P>0.05), and other metal elements were significantly different (P<0.05). The highest content of calcium and zinc in Xinjiang was 1758 mg and 14.3 mg, respectively, the highest content of metro in Ningxia was 240 mg, and the highest content of magnesium in Qinghai was 1790 mg. Except alanine, there was no significant difference in the other amino acids (P>0.05), and there was a certain difference in the characters and microstructure. The difference in microstructure was mainly manifested in stone cells and pericarp epidermal cells, but there was no significant difference in Rf value (P>0.05). Conclusion The 4 kinds of Lycium ruthenicum Murr. have different basic composition, metal element content and traits, which provide experimental basis and theoretical basis for further study of the health function of Lycium ruthenicum Murr.
