用分光光度法测定了黄河流域、长江流域16个省同一时期银杏叶中总黄酮的含量,测试结果表明,黄酮含量与生长地域有密切的相关性。据此,本文对各地域银杏叶的开发价值进行了评价,并对银杏叶的开发利用提出了建设性的建议,具有一定的宏观指导意义。为合理开发利用好我国这一特有资源提供可靠的理论依据。
The content of total flavonoids in Ginkgo biloba leaves of 16 provinces in the Yellow River Basin and the Yangtze River Basin during the same period was determined by spectrophotometry. The results showed that there was a close correlation between the content of flavones and the growth area. Therefore, this article evaluates the development value of Ginkgo biloba in various regions and puts forward constructive suggestions on the development and utilization of Ginkgo biloba, which has certain macro-guiding significance. Provide a reliable theoretical basis for the reasonable development and utilization of this unique resource in our country.
