Objective:To study the optimum extraction process of total flavonoids in Incarvillea arguta.Method: The orthogonal experimental design was used with the extraction yield of total flavonoids as the assessment index
water extraction volume
extracting time
extraction times as factors.The total flavonoids content extracted from I.arguta was determined by spectrophotometric method at detection wavelength of 498 nm.Result: The optimum extracting conditions were as follows: adding 10 fold of 0.5% NaOH-H2O
three times
heating for 3 hours.Rutin was linear in the range of 8.72-52.32 mg·L-1 and the average recovery was 101.98% with RSD of 1.23%.Conclusion: The optimum extraction process of total flavonoids in I.arguta was reliable and the determination method is easy and accurate which can be used for the extraction of total flavonoids in this herb.
