Content Determination of Total Flavonoids in Herba Gendrussae

Objective To research the content determination method and the extraction process of total flavonoids in Herba Gendrussae. Methods The chromogenic method with ultraviolet visible spectrophotometer was used to detect the content of total flavonoids in Herba Gendrussae. And the orthogonal experiment method was used to optimize the extraction process of total flavonoids. Results Rutin chromogenic method could accurately detect the content of total flavonoids, and the average content was 4.67 mg/g, the orthogonal experiment method to screen the optimal extraction process was 15 times of 60% ethanol, ultrasonic extraction for 40 min. Conclusion The chromogenic method with ultraviolet visible spectrophotometer can detect the content of total flavonoids accurately, and can be used to control the quality of Herba Gendrussae, the results of orthogonal experiment showed that the extraction technology was stable and feasible.
