Abstract:
OBJECTIVE: To optimize reflux extraction technology of total flavonoids from the roots and stems of Angelica sinensis. METHODS: The reflux extraction technology of total flavonoids from the roots and stems of A. sinensis was optimized by Box-Behnken design-response methodology based on single factor test using volume fraction of extraction solvent ethanol, solide-liquid ration, extraction time, extraction times as investigation factors, the content of total flavonoids in extract as evaluation index. RESULTS: The optimal extraction technology of total flavonoids from the roots and stems of A. sinensis was that volume fractions of ethanol were 70％ and 50％; solid-liquid ratios were 1: 40 and 1: 30; extraction time were 1. 3 h and 1. 7 h; The number of extraction times is two times. In verification test, the contents of total flavonoids were 7. 253 6, 25. 144 1 mg/g (RSD= 1. 57％, 1. 49％, n = 3); relative errors of those to predicted value (6. 942 8, 25. 703 5 mg/g) were 4. 28％, 2. 24％. CONCLUSIONS: Optimized extraction technology for total flavonoids from the roots and stems of A. sinensis is simple, reproducible and predictable.
