32种云南蕨类植物中的总黄酮测定

Total flavonoid contents of 32 kinds of fern plants in Yunnan Province

摘要: 采用分光光度法,以芦丁为标准品,对32种云南蕨类植物中总黄酮进行了测定.结果表明:所研究的32种云南蕨类植物中均含有黄酮类化合物,而且其中18种植物的总黄酮质量分数超过3%,总黄酮质量分数低于1%的仅有6种,表明蕨类植物是黄酮类化合物的极好资源,有待进一步开发利用.

Abstract: The total flavonoid contents of 32 kinds of fern plants in Yunnan Province was determined by spectrophotometry.The results showed that the fern plants contained flavonoids,and the total flavonids contents were different for the various ferns.The total flavonoid contents of 18 among the 32 kinds of fern plants were beyond 3%,which indicated that fern is a good resource of flavonoids,and it is necessary to study its chemical constituents and pharmacology.
