Abstract:
Objective To investigate the optimum extraction of total flavonoids and baicalin in baical skullcap root. Methods Ultraviolet spectrophotometry was used to detect the content of total flavonoids, HPLC was used to detect the content of baicalin. With the test of extracting method, time, frequency, and adding water volume, the optimum extracting craft was determined. Results The best craft for extraction was:heating water for recirculation, setting extracting time for 1.5 h, extracting frequency for 3 times, and water volume for 8 times of baical skullcap root. Conclusion The optimized process for extraction are stable, reasonable and feasible.
