Glabrous sarcandra herb extract and detection method of preparation thereof

The invention discloses a glabrous sarcandra herb extract and a detection method of a preparation thereof. The method comprises the following steps: (1) preparing a reference solution; (2) preparing a standard curve, namely measuring the reference solution, measuring the absorbance, and drawing a standard curve by taking the absorbance as a vertical coordinate and taking the concentration as a horizontal coordinate; (3) preparing a test solution; (4) measuring the test solution, measuring the absorbance, reading the amount of gallic acid in the test solution in the standard curve, and calculating, thereby obtaining the content of total phenols; (5) measuring the test solution, measuring the absorbance, reading the amount of gallic acid in the test solution in the standard curve, and calculating, thereby obtaining the content of the polyphenol which is not adsorbed; and (6) calculating the content of tannins in the test article. According to the method disclosed by the invention, the mass of the glabrous sarcandra herb extract and the preparation thereof can be well controlled, the mass control standard is further improved, and the stability, uniformity and controllability of the quality are guaranteed. According to the method, the tannin extraction efficiency and the result accuracy are further improved, and the inspection time is shortened.
