Abstract: Objective To optimize water extraction and alcohol precipitation technology for Qianyang Yuyin Granules. Methods With composite score of the content of stilbeneglycoside and dry extract yield as indexes, effects of the amount of water, extraction times and time on extraction technology were investigated by orthogonal test; the effects of relative density of concentrated liquid, the concentration of alcohol precipitation and standing time on alcohol precipitation technology were also investigated. Results Optimum extraction process was as following: extracting 2 times with 12 times the amount of water, 1 hour each time; Optimum alcohol precipitation technology was as following: the relative density of concentrated liquid 1.10 (60 ℃), the concentration of alcohol precipitation 60%, standing time 48 hours. Conclusion The optimum method is stable and feasible, which is suitable for industrial production of the preparation.

2 方法與結果
2.1 二苯乙烯苷含量測定
2.1.1 色譜條件 色譜柱:Hedera C18柱(4.6 mm×250 mm,5 μm);流動相:乙腈-水(19∶81);檢測波長:320 nm;柱溫:30 ℃;流速:1.0 mL/min;進樣量:10 μL[1]。
2.1.2 對照品溶液的制備 精密稱取二苯乙烯苷對照品17.90 mg,加稀乙醇溶解,制成每1 mL含二苯乙烯苷0.179 mg的對照品溶液。
2.1.3 供試品溶液及陰性對照溶液的制備 精密吸取樣品2 mL,置25 mL棕色量瓶中,加稀乙醇,超聲(功率280 W,頻率50 Hz)20 min,放冷,再加稀乙醇至刻度。搖勻,過濾,取續濾液,即得。取不含制何首烏的陰性樣品,同法制得陰性對照溶液。
