| 摘要: |
| 对石韦孢子叶和营养叶中的多糖、总黄酮和总皂甙含量进行测定和分析。结果表明:(1)孢子叶中活性成分含量的高低顺序为总黄酮>多糖>总皂甙,其中,总黄酮与多糖和总皂甙含量的差异均达到极显著水平(P<0.01),而多糖与总皂甙含量的差异则不显著(P>0.05); 营养叶则是多糖>总黄酮>总皂甙,且各活性成分含量间的差异均达到极显著水平(P<0.01)。(2)孢子叶与营养叶相比,多糖和总黄酮含量的差异均达到极显著水平(P<0.01),而总皂甙含量的差异不显著(P>0.05)。其中,多糖含量是营养叶高于孢子叶,而总黄酮含量则是孢子叶高于营养叶。(3)石韦叶片中多糖含量与总黄酮含量间存在极显著的负相关关系(P<0.01),而总皂甙含量与多糖和总黄酮含量的相关性均未达到显著水平(P>0.05)。 |

| Abstract: |
| The contents of polysaccharides,total flavonoides and total saponins in sporophyll and foliage leaf of Pyrrosia lingua were determined and analyzed. The results were as follows:(1)the functional composition content in the sporophyll was in a decreasing order of total flavonoides,polysaccharides and total saponins,and the content of total flavonoides differed significantly from the content of polysaccharides and total saponins(P<0.01),while the content of polysaccharides had no significant difference with the content of total saponins(P>0.05); the functional composition content in the foliage leaf was in a decreasing order of polysaccharides,total flavonoides and total saponins,and the differences of polysaccharides,total flavonoides and total saponins content were significant(P<0.01).(2)The contents of polysaccharides and total flavonoides were significantly different between the sporophyll and the foliage leaf(P<0.01),while the contents of total saponins in the sporophyll had no significant difference comparing with that in the foliage leaf(P>0.05),and the contents of polysaccharides in the foliage leaf were higher than that in the sporophyll,whereas the contents of total flavonoides in the sporophyll were higher than that in the foliage leaf.(3)There was significant negative correlation between the content of polysaccharides and total flavonoides in leaves of P.lingua(P<0.01),while the content of total saponins was not significantly related to the content of polysaccharides and total flavonoides(P>0.05). |
