    Journal: Zhong Yao Cai; 2006 Nov; 29(11):1233-5. PubMed ID: 17228667.
    Abstract:
    OBJECTIVE: To establish a method for the determination of acacetin in Xiangjuganmao Keli (no sweet). METHODS: Acacetin in powdered herb was extracted by ultrasonator with methanol and was hydrolyzed with hydrochloric acid. Separation was accomplished on an ODS reversed phase column (5 microm, 4.6 x 250 mm) with a mobile phase of methanol-water-acetic acid(350: 150: 2). The detective wavelength was at 340 nm. RESULTS: The method was accurate, the results were stable and reproducible. The linear range of calibration cure was within the concentration of 2.00 - 10.00 microg/ml (r = 0.9998). The average extraction recovery was 99.9% (n = 6), RSD = 0.41% (n = 6). CONCLUSION: The method is simple, convenient, sensitive, and reproducible for quality control of Xiangjuganmao Keli (no sweet).
