摘要
通过各种不同的方法提取元宝枫叶中的总黄酮，比较不同提取方法的提取率及提取物中总黄酮的含量，从而探讨最佳的提取方法。结果表明：７０％乙醇提取法和６０％丙酮提取法是两种较好的提取方法。对７０％乙醇提取方法进一步作了扩大性试验。为优选元宝枫叶黄酮提取工艺提供初步的科学依据。
Several methods were used to extract the flavonoids from the leaves of Acer truncatum . A comparision was conducted based on the extraction rate and the content of flavonoids in the extracts. The best methods were selected. The results showed that the methods of using 70% ethanol and 60% acetone are the best, and a methodological study was carried out on the extraction in industrial scale. The results provide the scientific basis for the production of flavonoids from the leaves of A. truncatum.
