2. CONTENT AND OPTICAL ROTATION TEST

Content and optical rotation test is performed in Analyzing and Test Center of Guangzhou Institute of Chemistry, Chinese Academy of Science

The test report shows:

        a. Purity of ABA is 107%, compared to Sigma’s (±)-Abscisic acid (A1049, 98.5%, HPLC)  

        b. Optical Rotation: [a]D25 = +432°
