【Abstract】 Objective: To optimize the best extraction process of volatile oil from Maocangzhu(Atreactylodis Rhizoma). Methods: Single-factor and orthogonal design were used to optimize the extraction process of volatile oil from Maocangzhu by steam distillation, by taking the extraction rate of volatile oil as the index, the influence of material-to-liquid ratio, soaking time and extraction time were surveyed on the extraction yield of volatile oil. Results: The best material-to-liquid ratio of volatile oil from Maocangzhu was 1 ∶10, no soaking, ultrasound for 30 minutes, extracting for eight hours, extraction yield of volatile oil was 4.80%, RSD value of three times extraction was 1.25%. Conclusion: The extraction process, stable, feasible, accurate and rational, could provide theoretical evidence for the extraction of volatile oil from Maocangzhu.更多还原
