Study on Extraction Process and Content Determination of Safflor Yellow

Abstract:

The aim was to study the extraction process of safflor yellow (SY) from Cacthamus tinctorius. The SY contents of five varieties which were planted in safflower production base in Tianjin were measured and compared, in order to determine its growth adaptability and herbal quality. [Method Based on the single-factor test, the optimum extraction process can be obtained after selecting the lager factor which affected extraction rate of safflor yellow. Then the SY contents of five varieties were determined by UV-visible spectrophotometer. [Result The orthogonal test showed that the optimal extraction process was to add 10 and 12 times amount of water and extract for 30min every time at 60°C, totally for 2 times. The SY contents of five varieties were significantly higher than or equal to the standard medicinal safflor. [Conclusion Five varieties of safflower which were planted in Tianjin showed good adaptability and herbal quality. This study would provide scientific basis for improving saline-alkali soil in Tianjin.
