Objective: This study aimed to develop a green and efficient extraction technology of total saponins from Ophiopogon japonicus, in order to improve the problems of low efficiency and environment friendliness in the traditional extraction process of total saponins from Ophiopogon japonicus. Methods: Single factor experiments were carried out to investigate the effect of different extraction conditions on the extraction effect. The key factors were selected for orthogonal experimental design to determine the optimal extraction conditions. Results: The optimum extraction parameters of total saponins from Ophiopogon japonicus were obtained by orthogonal experiment analysis as follows: solid-liquid ratio 1:50 ml, extraction temperature 60？C, water content 40%, extraction time 30 min. Under these conditions, the highest extraction rate of total saponins from Ophiopogon japonicus was 3.92%. Conclusion: The use of low eutectic solvent extraction and the optimization of orthogonal experiments can extract the total saponins of Ophiopogon japonicus in an efficient and environmentally friendly manner. This process not only improves the extraction efficiency, but also helps to reduce the environmental pollution, which has important practical application value.
