ABSTRACT
Objective To determine the contents of methylophiopogonanone A (MOA) and methylophiopogonanone B (MOB) in Radix Ophiopogonis and its extracts. Methods An HPLC-UV method was used for determining the contents of MOA and MOB in all samples. Analytical column was Kromasil C18 (250 mm?4.6 mm, 5 ?m). Mobile phase was acetonitrle-water (55∶45) and detection wavelength was 298 nm. The flow rate of mobile phase was 1 mL/min, and temperature was 30 ℃. Results The contents of MOA in Radix Ophiopogonis cropped in Sichuan and Zhejiang Provinces were 0.004 0%-0.009 6%, 0.006 7%-0.013 4%, and the contents of MOB were 0.002 1%-0.006 2%, 0.015 9%-0.028 2%, respectively. The contents of MOA in the extract of Radix Ophiopogonis cropped in Sichuan and Zhejiang Provinces were 0.007 5%-0.008 8%, 0.011 2%-0.012 6%, and the contents of MOB were 0.003 8%-0.005 1%, 0.020 7%-0.023 8%, respectively. Conclusion The contents of MOA and MOB in Radix Ophiopogonis cropped in Zhejiang Province and its extracts are more than those in Sichuan Province and its extrouts. The method can be used for the purpose of the quality control of Radix Ophiopogonis and its extracts.
