Abstract:
Objective To optimize the extracting condition of total isoflavones from Fructus Sophorae by subcritical water extraction.Methods Taking isoflavones yield as index and genistin as control,the technology parameter of subcritical water extraction of Fructus Sophorae isoflavones was optimized by single factor and orthogonal experiment.Results The yield of Fructus Sophorae total isoflavones in the extracts was 23.3% at 130 ℃ for 45 min with the liquid-solid ratio of 12.5 mL/g.Conclusion Compared with traditional extracting methods,subcritical water extraction is a new developing technology in recent years.Its advantage is fast,good-selective.
