ABSTRACT

Objective:

To evaluate the quality of Maiweishen, a simple and accurate HPLC method for determining the contents of 20 active constituents from Maiweishen was established.

Methods:

The chromatographic separation was achieved on a C18 column (150 mm × 4.6 mm, 5 μm) using a mobile phase made up of acetonitrile and water at a flow rate of 1.0 mL/min. The detection wavelength and column temperature were set as 203 nm and 35 ℃, respectively.

Results:

Sixteen ginsenosides (Rg1, Re, Rf, Rb1, Rg2, Rc, Rb2, Rb3, F1, Rd, F2, Rg3, protopanaxatriol, compounds K, Rh2, and protopanaxadiol), three kinds of lignan in Schisandra chinensis (schizandrol A, schizandrin A, B), and ophiopogonin D were separated at baseline with good linearity (r ≥ 0.999 6). The recovery rates were 96%-102% (RSD < 2%).

Conclusion:

The method is simple, fast, accurate, and could be applied to the quality control of Maiweishen.
