Abstract:

To establish a method for the total coumarins content at the wavelength of 348 nm，scopoletin was used as the reference substance.The linear range was 0～0.020 mg/mL，r=0.999 2. The average recovery was 102.44%，RSD=1.81%（n=9）. Ultraviolet spectrometry was developed to determine total coumarins in noni juice fermented with different time. The contents of Noni jucie fermented with 25~500 d were in 0.176~0.243 mg/mL range. This method is simple，rapid，accurate and repeatability，which can be applicable for determination of coumarins content in liquid samples and the result was stable with the fermentation time extended.
