通过正交实验方法,对影响连翘醇提取条件的因素进行了探讨。结果表明,连翘总提取物最佳提取条件为8倍量80%乙醇,80℃提取4次,每次1.5h;连翘苷最佳提取条件为6倍量50%乙醇,80℃提取2次,每次1.5h;0.1g生药/mL连翘提取液对枯草杆菌的抑菌作用明显,其最佳提取条件为8倍量80%乙醇,60℃提取3次,每次1.5h。该实验得到的优化提取条件简便易行,可根据实际需要选择不同的提取条件。
Through orthogonal experimental methods, the factors that affect the fining conditions of Forsythia suspensa alcohol were discussed. The results showed that Forsythia suspensa total extract optimum extraction conditions of 8 times the amount of 80% ethanol, 80 ℃ extracted four times, each 1.5h; Forsythin optimum extraction conditions 6 times the amount of 50% ethanol, 80 ℃ extraction 2 Times, each 1.5h; 0.1g crude drug / mL Forsythia suspensa extract Bacillus subtilis antibacterial effect was obvious, the best extraction conditions for eight times the amount of 80% ethanol, 60 ℃ extracted three times, each 1.5h. The experimental optimization of the extraction conditions is simple and easy, according to the actual need to choose different extraction conditions.
