- 摘要:
- 以市售瓦松为试材，采用索氏提取法，利用单因素试验和正交实验，考察了料液比、提取时间、药粉目数、乙醇浓度4个因素对其总黄酮提取率的影响，并优化了提取工艺。结果表明：索氏提取法提取瓦松总黄酮的最佳工艺条件为料液比1∶15 g/mL、提取时间3 h，目数100目，乙醇浓度75%，在此条件下提取率为0.63%。该方法提取量稳定、操作简单、可行。
- Abstract:
- To study and optimize the extraction procedure of total flavonoids from Orostachys fimbriatus(commercially available),the single factor experiment and orthogonal experiment were applied to investigate the influence of factors like solid-liquid radio，extraction time，powder mesh and ethanol concentrate upon the yield of the total flavonoids by Soxhlet extraction method.The results showed that the optimal conditions were 1∶15 g/mL of solid-liquid ratio，3 h of extraction time，100 meshes of Orostachys fimbriatus powder,75% of ethanol concentration.In this condition，yield of the total flavonoids was 0.63%.The procedure is simple，stable and efficient.
