| titleOfInvention | Method for determining content of chlorogenic acid, luteolin and apigenin in spider fruits |
| abstract | The invention discloses a method for measuring the content of chlorogenic acid, luteolin and apigenin in a spider fruit medicinal material, which comprises the following steps: chromatographic conditions are as follows: a chromatographic column: pntulips BP-C 18 (4.6 mm. times.250 mm, 2.5 μm); mobile phase: the mobile phase A is acetonitrile, the mobile phase B is methanol, the mobile phase C is 0.1 percent phosphoric acid water solution, and gradient elution is carried out; detection wavelength: 330-350 nm; column temperature: 20-30 ℃; flow rate: 0.8 to 1.2mL/min ‑1 (ii) a Sample introduction amount: 5-15 muL; preparing a reference substance solution; preparing a test solution; and (4) measuring by an HPLC method. The invention adopts an HPLC method, establishes a one-test-multiple-evaluation method for determining the content of active ingredients in the valeriana jatamansi maxim medicinal material by optimizing an extraction method and chromatographic conditions, and provides a research basis for formulation of quality standards of the medicinal material, reasonable development and utilization of resources and the like. The determination method is accurate, high in sensitivity, good in repeatability and reliable in result, and provides a basis for quality control and evaluation of the spider fruit medicine. |
