摘　　要：[Objectives] To optimize the extraction process and determine the total triterpenoids from Semen Trichosanthis.[Methods]The Box-behnken response surface methodology was applied to optimize the extraction conditions of total triterpenoids in Semen Trichosanthis.And the spectrophotometry was used to determine the content of total triterpenoids in Semen Trichosanthis.[Results] The optimal extraction conditions were solid to liquid ratio of 40∶ 1,ultrasonic time of 20 min,and ultrasonic power of 100 W.Under these conditions,the content of total triterpenoids in Semen Trichosanthis was significantly different among the 10 production areas,among which the No.9 production area(Anhui 1) had the highest total triterpenoids content of 45.71 mg/g,while No.7 production area(Shandong) had the lowest total triterpenoids content of 15.22 mg/g.[Conclusions]The Box-behnken response surface methodology is reliable for the extraction of total triterpenoids in Semen Trichosanthis,and the spectrophotometry is proper for determining the content of total triterpenoids in Semen Trichosanthis.There are large differences in the content of total triterpenoids in Semen Trichosanthis produced in different areas.[Objectives] To optimize the extraction process and determine the total triterpenoids from Semen Trichosanthis.[Methods]The Box-behnken response surface methodology was applied to optimize the extraction conditions of total triterpenoids in Semen Trichosanthis.And the spectrophotometry was used to determine the content of total triterpenoids in Semen Trichosanthis.[Results] The optimal extraction conditions were solid to liquid ratio of 40∶ 1,ultrasonic time of 20 min,and ultrasonic power of 100 W.Under these conditions,the content of total triterpenoids in Semen Trichosanthis was significantly different among the 10 production areas,among which the No.9 production area(Anhui 1) had the highest total triterpenoids content of 45.71 mg/g,while No.7 production area(Shandong) had the lowest total triterpenoids content of 15.22 mg/g.[Conclusions]The Box-behnken response surface methodology is reliable for the extraction of total triterpenoids in Semen Trichosanthis,and the spectrophotometry is proper for determining the content of total triterpenoids in Semen Trichosanthis.There are large differences in the content of total triterpenoids in Semen Trichosanthis produced in different areas.
