First, this research developed a set of simple and effective technologies for preparative extraction and separation of flavonoid and phloridzin from Lithocarpus polystachyus, which includes:(1) Microwave-assisted extraction of flavonoid from tender leaves of Lithocarpus polystachyus Rehd. The extraction conditions are as the follows, 1.2 % of Ca2 water solution, solid-liquid ratio of 1:12, pre-boiling for 5 min, 800 W of microwave treating for 25 min.

本研究首先研发出一套简单、有效的制备性提取分离多穗柯黄酮类及其根皮苷工艺，这套工艺包括：(1)微波辅助氢氧化钙水溶液提取多穗柯黄酮，最佳工艺条件为用1.2 %氢氧化钙水溶液为提取液，料液比1：12，预煮时间5min，微波功率800W处理25min。

In Huaihua than in the old leaves, and the content was the least in stem. Conclusion: The optimum conditions for extracting total flavonoids from Lithocarpus polystachyus Rehd. were material to 70% ethanol concentration ratio 1:35, ultrasonic power 540W, and extraction time15 min.

以原料35倍量的70%乙醇作为溶剂，在提取功率600W、提取时间15min的条件下，即可获得多穗柯总黄酮最佳提取效果；8~10月采摘嫩叶存放时间越短，总黄酮含量越高。

Using design of L9 (3^4), the extraction conditions of total flavonoids from Lithocarpus polystachyus Rehd. in Huaihua were optimized by ethanol solution extraction assisted with ultrasonic, and the variety trends of total flavonoids content were investigated with different natural storage time, different gathering seasons, differrent Lithocarpus polystachyus Rehd.

以怀化产多穗柯为原料，采取乙醇为溶剂超声波辅助提取，以L9(3^4)正交试验方法优化总黄酮提取工艺，然后在该工艺条件下对自然存放时间不同、采摘季节不同、不同叶的多穗柯原料进行总黄酮含量的动态变化考察。
