  • Title: [Determination of adenosine and thymidine in Fritillaria bulbs by ultraviolet spectrophotometry].
    Author: Xu R, Lu Y, Chen Z.
    Journal: Zhongguo Zhong Yao Za Zhi; 1997 Nov; 22(11):682-3, 704. PubMed ID: 11243187.
    Abstract:
    A convenient method for quantitative analysis of the nucleosides in Fritillaria bulbs has been developed by means of thin layer chromatography and ultraviolet spectrophotometry. The MeOH extracts from four species of Fritillaria were analyzed with this method. The results show that both adenosine and thymidine in the four species are quite disparate, suggesting that the nucleosides may be responsible for the anti-coagulative activity of Fritillaria.
