Objective:To determine the content of luteolin in Cyperi Rhizoma and Cyperi Rhizoma fried with vinegar from different areas.Method: The content was determined by HPLC and the measurement conditions were used as following: kromasil C18(4.6 mm × 150 mm
5 μm);mobile phase: methanol-water with 0.2% phosphoric acid(55∶ 45);the flow rate: 1.0 mL.min-1;measurement wavelength 350 nm.The temperature of column 30 ℃.Result: The linear range of luteolin was ranged from 0.040 81 to 0.367 2 μg(r = 0.999 4).The content of luteo-lin was 57.35 μg·g-1 in Cyperi Rhizoma from Tai’an Shandong
which was the highest in 8 different areas
and 17.82 μg·g-1
the lowest from Yunnan
China.The content of luteolin from most areas exceeded 22.00 μg·g-1.The content of luteolin in Cyperi Rhizoma fried with vinegar from different areas was higher than these herbs before fring with vinegar.Conculsion: The study supplies a scientific basis for the content of luteolin in Cyperi Rhizoma and Cyperi Rhizoma fried with vinegar.
