Melt Point: 156-157C
Solubility: Soluble in ethanol, methonal and other organic solvents, not dissolve in water。
2. Quality standards testing
2.1 Identification: (reference substance: Artemisnin)
2.1.2 TLC examination: reference substance Rf value and color are consistency
2.1.3 IR inspection: in line with the reference substance fingerprint (infrared absorption spectra)
2.2 HPLC Chromatogram of Artemisnin 98%
2.2.1 Theory
Detection the concentration of Artemisnin in the samples by using a standard working curve
2.2.2 Reagents and equipment
Chromatography grade methanol
High Performance Liquid Chromatogram equipment
Ultrasonic equipment
2.2.3 Liquid sample configuration
Accurately take 5mg of 98% Artemisnin samples, dissolved with appropriate chromatography grade methanol, Calibration volume to 10mL, ultrasound 30mins and laying 10min, using 0.45μm membrane filtrate, as the sample liquid reserve.
2.2.4 Preparation of standard solution
Accurately take 100mg Artemisnin standard, dissolved with chromatography grade methanol and calibrate volume to 10mL.
2.2.5 Detect conditions:
Chromatography Column: KYWG, C18(2504.6)mm, 5μm
Mobile phase: 0.01mol/L disodium hydrogen-disodium hydrogen buffer : Methanol (55:45)
Velocity: 1 mL/min
Test wave: 260 nm
2.2.6 Standard curve
Accurately take 0.20mL, 0.15mL, 0.1mL, 0.05mL, 0.00mL to 10mL flask, Calibrate volume respectively, made concentration of 1mg/mL, 0.75mg/mL, 0.5mg/mL, 0.25 mg/mL, and 0.00mg/mL solution of the reference substance. Using the method of 2.2.5 to detect those solutions, the concentration as the vertical coordinates and the peak area as Abscissa, rendering the standard curve, and elicit to the regression equation.
2.2.7 Sample content test
Detect the sample liquid as 2.2.5s method; calculate the peak area and its content by the standard working curve.
