Physical and Chemical Properties Molecular structure of type: Polyphenol compounds Melt Point: 253℃～257℃ Solubility: Difficult to dissolve in water, soluble in ethanol, acetone and other organic solvents 2.

Quality standards testing 2.1 Identification: 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 15%Rosmarinic acid 2.2.1 Theory Detection the concentration of resvertration 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% Rosmarinic acid 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 resveratrol standard, dissolved with chromatography grade methanol and calibrate volume to 10mL.

2.2.5 Detect conditions: Chromatography Column: KYWG, C18(250×4)mm, 5μm Mobile phase: 27% acetonitrile aqueous solution Velocity: 1.2 mL/min Test wave: 303 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.
