Embodiment 1

[0020] 1. The content determination method for simultaneous determination of two components is:

[0021] 1.1 Medicinal materials, instruments and reagents

[0022] Self-made vinegar chamaejasma: Weigh 100g of chamaejasma decoction pieces (LD), stir-fry continuously and evenly at 160°C for 10min (CLD1), 20min (CLD2), 30min (CLD3), 40min (CLD4) until the surface of the medicine turns brown-yellow . Three batches were concocted. The obtained sample names are CLD11, CLD21, CLD31, CLD41, CLD12, CLD22, CLD32, CLD42, CLD13, CLD23, CLD33, CLD43, respectively.

Abstract

The invention relates to a quality control method for euphorbia fischeriana steud processed with vinegar, and belongs to the field of traditional Chinese medicine decoction piece quality control, wherein the quality of euphorbia fischeriana steud processed with vinegar is judged by measuring the contents of diterpenoid components such as Prostatin and Pekinenin G in euphorbia fischeriana steud processed with vinegar. According to the present invention, the quality control method for euphorbia fischeriana steud processed with vinegar is established, and the quality control method for simultaneous determining the contents of the two toxic and pharmacological components such as Prostratin and Pekinenin G in euphorbia fischeriana steud processed with vinegar by using high performance liquid chromatography is provided, wherein the quality standard is simple, and the drug quality can be well controlled; and the quality control method has advantages of strong specificity and good reproducibility, and truly reflect the safety, the effectiveness and the controlled quality of the drug.
