摘　　要：目的 :优选展筋乳剂提取工艺。方法 :考察提取时间对挥发油提取得率的影响 ;采用正交试验 ,以浸膏得率和三七总皂苷含量考察醇提工艺条件。结果 :当归、乳香、没药 3味药物水提 3h可使挥发油馏出 95 % ;三七、伸筋草、秦艽 3味药物用乙醇提取 ,乙醇浓度 (A)、提取次数 (B)、提取时间 (C)、乙醇用量 (D) 4因素中 ,A ,B对浸膏得率有显著性影响 ,对提取液中三七总皂苷含量均无显著性影响。乙醇提取最佳工艺为药材用 5倍量 6 0 %乙醇提取 3次 ,每次 1h。 3批验证结果浸膏得率 2 6 .5 % ,三七总皂苷含量 17.2 8mg·g-1。结论 :上述实验结果可为展筋乳剂提取工艺的确定提供实验依据。Objective: To select the optimum extraction process of Zhanjin Ruji. Method:To observe influence of extraction time upon the extraction rate of volatile oil, the orthogonal test was adopted to observe the extraction process by alcohol from the extraction rate and content of the total saponins in Radix Notoginseng. Result: The three kinds of herbs including Radix Angelicae Sinensis, Resina Olibani and Myrrha were extracted with water for 3 hours,95% of volatile oil can be distilled. The three kinds of herbs including Radix Notoginseng, Herba Lycopodii and Radix Gentianae Macrophyllac were extracted by alcohol. Four factors such as alcohol concentration( A ), extraction times( B ),extraction time( C ), and solvent amount( D ),had not significant effect on the content of total saponins in Radix Notoginseng in herbal extraction, but factor A and B had significant effect on the extraction rate. The optimum extraction process was as follows extracted with 5 times the amount of the solvent volum 60% alcohol for 3 times and with each time for 1 hour. Three times experiments showed that the extraction rate was 26.5% and the content of the total saponins in Radix Notoginseng was 17.28% mg·g -1 . Conclusion:The above experimental reaults can provide experimental basis for deciding the extraction process of Zhanjin Ruji.
