不同产地黑果枸杞中原花青素和花青素含量研究

Study on proanthocyanidins and anthocyanins contents of Lycium ruthenicum Murr.from different areas

  • 摘要: 在溶剂提取法基础上,采用香草醛-盐酸显色法测定不同产地黑果枸杞果实原花青素的含量,采用消光系数法测定花青素含量,为人工种植高品质黑果枸杞提供理论依据。结果表明:原花青素含量范围为14.2690.24 mg/g(烘干粉),花青素含量范围为0.698.40 mg/g,黑果枸杞果实中原花青素含量明显高于花青素含量。不同地区野生黑果枸杞中原花青素和花青素依次为青海格尔木>新疆阿克苏>青海诺木洪>新疆库尔勒>内蒙古额济纳旗。此外,格尔木人工露地种植黑果枸杞原花青素含量显著高于(p<0.05)格尔木野生的黑果枸杞,说明人工栽培黑果枸杞可能是一种更好的方式。在水、肥、阳光充足的条件下,选择性状表现好的品种,可实现北京人工栽培的黑果枸杞果实原花青素和花青素含量达到原产地人工栽培的水平。 

     

    Abstract: Based on the method of traditional solvent extraction,the proanthocyanidins contents of Lycium ruthenicum from different producing areas was determined by spectorphotometry with vanillin- Hydrochloric acid as the color- developing agent. The anthocyanins contents were determined by extinction coefficient method. The results showed that proanthocyanidins and anthocyanin content range was 14.26~90.24 mg / g and 0.69~8.40 mg / g( dry powder).It meant that the content of proanthocyanidins was significantly higher than that of anthocyanins.The content of proanthocyanidins from wild L.ruthenicum in Golmud Qinghai was significantly higher than that in other places,in which the contents were Aksu Xinjiang > Nomhon Qinghai > Kuerle Xinjiang > Ejinaqi Inner Mongolia.The content of proanthocyanidins from cultivated L. ruthenicum in Golmud Qinghai was significantly higher than that from wild L.ruthenicum( p < 0.05).It showed that artificial cultivation of L.ruthenicum was a better way.The contents of proanthocyanidins and anthocyanins from cultivated L.ruthenicum in Beijing can be equal to those in the origin under the condition of abundant water,light and fertilizer.
