摘要
以海南省儋州、五指山和东方地区野生裸花紫珠为材料,研究其不同部位活性成分含量差异,为合理开发利用裸花紫珠资源提供理论依据。结果表明:裸花紫珠不同部位活性成分含量存在显著(P<0.05)差异。总黄酮在不同部位中含量为:花>全枝>叶片>果实>茎;多糖含量顺序为:花>叶片>全枝>果实>茎;浸出物含量顺序为:花>叶片>全枝>果实>茎。因此,裸花紫珠中活性成分含量以花最高,茎最低;在花器官中,3个地区的种质间总黄酮和多糖存在显著(P<0.05)差异,而水溶性浸出物差异不显著(P>0.05)。
The active ingredients（water-soluble extract,total flavonoids and polysaccharide）in different parts of Collicarpa nudiflora Hook.Et Arn.were studied,and the theoretical basis for the rational development and utilization was also provided.The results showed the active ingredients of different parts were significant correlations（P0.05）,the different parts of total flavonoids are flowertotal branchesleavesfruitstem,and polysaccharides and water-soluble extract are flowerleavestotal branchesfruitstem.Therefore,the active ingredient contents in flowers and stem were the highest and lowest,respectively.Three C.nudiflora accessions had significant correlations（P0.05）with contents of total flavonoids and polysaccharide in flower,and the water-soluble extract has no significant correlations（P0.05）.
