目的:优选岗松总黄酮的提取工艺条件。方法:以总黄酮含量为指标,乙醇体积分数、固液比、提取时间为考察因素,采用星点设计-效应面法优选岗松中总黄酮的提取工艺,并进行预测分析。结果:最佳提取工艺为加16倍量70%乙醇提取3次,每次60 min,总黄酮平均质量分数1.43%。结论:实测值与预测值吻合度高,预测性良好,优选的提取工艺合理可行。 Objective: To optimize the extraction conditions of total flavonoids from Gangsong. Methods: Total flavonoids content as an indicator, ethanol volume fraction, solid - liquid ratio, extraction time as the investigation factor, the star point design - response surface method optimization of the extraction of total flavonoids in the pine and prediction analysis. Results: The optimum extraction process was extraction of 16 times 70% ethanol three times, each time 60 min, the average content of total flavonoids 1.43%. Conclusion: The measured values ​​are in good agreement with the predicted values ​​and have good predictability. The optimal extraction process is reasonable and feasible.
