不同地区野生金线莲有效成分含量的比较

目的:探究闽东、三明、泉州3个地区6个县野生金线莲有效成分含量的差异。方法:采用紫外分光光度法对其多糖、氨基酸、黄酮、生物碱含量进行测定。结果:闽东4个县野生金线莲的多糖、总氨基酸、总黄酮、生物碱含量均高于德化金线莲,多糖高14.0%~26.0%,总氨基酸高10.1%~20.4%,总黄酮高14.1%~28.1%,生物碱高3.7%~19.5%,差异显著或极显著;周宁、寿宁野生金线莲的黄酮、生物碱含量也高于永安金线莲,黄酮高6.9%~13.9%,生物碱高2.2%~5.4%,差异显著。结论:闽东野生金线莲有效成分含量较高,具有一定开发和利用优势。本试验研究结果对于进一步开发利用野生金线莲资源,组织培养材料的选择和大量发展金线莲产业具有一定指导意义。

The Comparison of Effective Composition Content in Different Localities of Wild Anoectochilus rox-burghii

To explore the differences of the effective composition content of wild Anoectochilus roxburghii in the six counties of Mindong,Sanming and Quanzhou in Fujian. The determination of the content of polysaccharide,the total flavonoids,the total amino acids,the total alkaloids of wild Anoectochilus roxburghii was by UV spectrophotometry. Results shows that the content of polysaccharide,flavonoids,amino acids,alkaloids of wild Anoectochilus roxburghii in the four counties of Mindong area is higher than that in Dehua County,the polysaccharide content is higher by 14.0%~26.0%,the total amino acid content is higher by 10.1%~20.4%,the total flavonoids content is higher by 14.1%~28.1%,and the total alkaloid content is higher by 3.7%~19.5%,between which existing significant or ex?tremely remarkable differences;The content of flavonoids and alkaloids of wild Anoectochilus roxburghii in Zhouning and Shouning County is also significantly higher than that in Yong'an County,the total flavonoids content is higher by 6.9%~13.9%,and the alkaloid content is higher by 2.2%~5.4%. On the whole,the active ingredients of wild An?oectochilus roxburghii in Mindong area are higher,showing certain advantages of development and utilization. This test result has certain guiding significance for the further utilization of wild Anoectochilus roxburghii,for the choice of tissue culture materials,and for the massive development of Anoectochilus roxburghii industry.
