Objective:
To study the optimum enzyme extraction process of total flavonoids from Cryptotaenia japonica.
Methods:
The process was optimized by single factor experiments and orthogonal, the yield of total flavonoids was used as index.
Results:
The optimum extraction technology was as follows: enzyme dosage: 1U/mL, pH value: 6.0, enzymatic hydrolysis temperature: 60%, enzymatic hydrolysis time: 1 h, the rate of material to liquid: 1 : 30, extraction temperature: 70 degrees C, extraction time: 1 h, the average extraction rate of total flavonoids from Cryptotaenia japonica was 4.76%.
Conclusion:
The method is an effective way to extract total flavonoids from Cryptotaenia japonica with high extract rate.
