Physical and Chemical Properties Molecular structure of type: Sesquiterpene lactone compounds Molecular formula and weight: C15H22O5 282.33 Melt Point: 156-157°C 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(250×4.6)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 2.2.5’s method; calculate the peak area and its content by the standard working curve.
