Studies on the Determination Methods and Extraction Technology of Total Flavonoids from Myoporum Bontioides A. Gray

Li Jiewen,Cai Guoxian,He Tingyu,Gu Wenxiang(College of Sciences,South China Agricultural University,Guangzhou 510642,China)  
The content of flavonoids of myoporum bontioides A.Gray was determined by using ultraviolet spectrophotometry,rutin as the standard substance,and the extraction conditions of flavonoids of myoporum bontioides A.Gray were studied by using orthogonal test.The results showed that the AlCl3 was suitable for the determination of the flavonoids content and the RSD of stability and precision was 0.506 %、1.30 %、4.20 %,respectively.And the factors affecting the extraction quality were in the order of the extracting temperatureethanol concentrationextracting timeratio of solid to liquid,and the yield of flavonoids of myoporum bontioides A.Gray was up to 5.15 % at the optimal extraction conditions with 60 % of ethanol and solid to liquid ratio of 1∶25 at the 90 ℃,which were extracted three times,2 h per time.
