Objective To establish a method for the determination of luteoloside, apigenin-7-O-β-D-glucosidase, and luteolin by high performance liquid chromatography (HPLC) method, and the determination of luteoloside, apigenin-7-O-β-D-glucosidase, and luteolin in Humulus scandens female and male plants from different origins and different harvest months in Hebei province. Methods HPLC method was used for simultaneous determination of luteoloside, apigenin-7-O-β-D-glucosidase, and luteolin. System suitability conditions were as follows: column: Agilent 5 TC-C18 (250 mm×4.6 mm, 5 μm); mobile phase: acetonitrile-0.2% phosphoric acid; flow rate: 1.0 mL/min; detection wavelength: 340 nm; column temperature: 25℃; injection volume: 10 μL. Results The linear ranges were 4.640-74.24 μg/mL of luteoloside (r=0.999 2), 1.510-30.20 μg/mL of apigenin-7-O-β-D-glucosidase (r=0.999 9), and 0.796 3-12.74 μg/mL of luteolin. RSD of precision, stability, and repeatabillity tests were≤1.99%. The average recoveries were 102.69% (RSD=1.64%, n=9), 100.49% (RSD=1.93%, n=9), and 100.39% (RSD=1.65%, n=9). Conclusion The method is simple, reproducible, and accurate, and reliable measurement results can be used for simultaneous determination of luteoloside, apigenin-7-O-β-D-glucosidase, and luteolin in H. scandens female and male plants from different origins and different harvest months in Hebei province. There is greater difference between luteoloside, apigenin-7-O-β-D-glucosidase, and luteolin in H. scandens female and male plants from different origins and different harvest months in Hebei province.
