    Author: Lu HW, Zhu BH, Liang YK.
    Journal: Zhongguo Zhong Yao Za Zhi; 2002 Mar; 27(3):192-4. PubMed ID: 12774398.
    Abstract:
    OBJECTIVE: To establish a method for the determination of curculigoside in Curculigo orchioides, a species of crude medicine. METHOD: The methanol was used as the solvent of exatraction and the curculigoside was extracted from the crude medicine with the method of the ultrasonic vibration. Using Sep-Pak C18 cartridges to purify the solution, the curculigoside was detected by HPLC. Intersil ODS-3(150 mm x 4.6 mm, 5 microns) chromatographic column was used, mobile phase of methanol-water-ice acetic acid (45:80:1) and detect wavelength was set at UV 283 nm. RESULT: The average recovery was 99.2% for the determination of curculigoside, RSD = 1.7% (n = 5). The content range of the curculigoside for 6 kinds of different samples was from 0.11% to 0.35%. CONCLUSION: This method could be used to control the quality of crude medicine C. orchioides.
