The total flavonoids content of peanut hulls of different sources were evidently different,those peanut hulls contained more total flavonoids from Shandong province,higher maturity and raw. This suggested that attention should be paid to the choice of peanut hulls as medicine materials. 3.The optimized extraction technology conditions considering the two indices of total flavonoids andβ-sitosterol were: the peanut hulls were extracted by 95% acohole 6 times of the hulls weight refluxing for 2 hours first,and extracted by 70% acohole 4 times of the hulls weight refluxing for 2 hours at the temperature below 80℃successionally,then the concentrate was dried vacuumizedly with the additament of starch 2% of the concentrate weight after the extracts were fitrated,united and concentrated. 4.The dried extract powder possessed high hygroscopy and low fluidity,but the weight variation of capsule contents could comply with the requirement of CP if it was mixed with dextrin and granulated by sieving 40 meshes using 95% ethanol as the wetting agent,and filled into capsules after dried below 60℃.The critical relative humidity of the granules was about 63%.

不同来源的花生壳总黄酮含量有较大差异，山东产区、成熟度高的及未经炒制的花生壳总黄酮含量较高，提示作为药材时应注意选择； 3、兼顾总黄酮及β-谷甾醇的最佳提取工艺为：先以95%乙醇6倍量加热回流提取2小时，再以70%乙醇4倍量80℃以下回流提取2小时，提取液过滤、合并、浓缩，加2%淀粉60℃以下减压干燥； 4、浸膏粉吸湿性大，流动性差，但加糊精并以95%乙醇为润湿剂、过40目筛制粒，60℃以下烘干后填充胶囊，可保证装量差异符合要求；颗粒临界相对湿度约为63%。

The method comprises following steps: taking diphenol and 3- trifluoromethyl- 4- chloronitrobenzene as raw material, salt precipitating for diphenol and potash, refluxing with water- containing toluene, reacting with 3- trifluoromethyl- 4- chloronitrobenzene and getting dinitro monomer; taking dinitro monomer, ferro powder and HCl as raw material, ethanol and water as disslovant for refluxing and ethanol recrystallization, getting fluorine- containing aromatic diamido monomer.

合成方法是以二酚与3-三氟甲基-4-氯硝基苯作原料，先将二酚与碳酸钾成盐，甲苯带水回流反应，然后与3-三氟甲基-4-氯硝基苯反应制得二硝基单体；再以二硝基单体，铁粉，HCl为原料，乙醇和水做溶剂，回流反应、乙醇重结晶，得到含氟芳香二胺基单体。

Results The optimum conditions for the extraction of Peucedanum praeruptorum Dunn was as follow: 80 % alcohol was used as solvent, and 8 times the amount of alcohol was added, the mixture was kept refluxing for 1.0 h for the first time; then 6 times the amount of alcohol was added and the mixture was kept refluxing for 0.5 h for the second time; Four times the amount of alcohol for 0.5 h for the last time.

结果 白花前胡的最佳提取工艺为用质量分数80 %的乙醇提取3次，提取时间分别为1.0、0.5、0.5 h，3次所用溶媒量分别为药材质量的8、6、4倍；按照筛选出的最佳工艺条件进行的3次重复性实验，测得浸膏中8-甲氧基补骨脂素含量质量分数为0.094 %，折合1 g生药中含量为0.171 2 mg，与预测值基本一致。
