fritillaria ruthenica/adenosine

A method for the determination of adenosine in Fritillaria bulbs was developed using thin layer chromatography and ultraviolet spectrophotometry. This method has been used in the analysis of adenosine in seven species of Fritillaria.

A convenient method for the quantitative analysis of adenosine and thymidine in Fritillaria bulbs was developed by means of dual wavelength ultraviolet spectrophotometry. This method has good linear relationship and the interrelated coefficient of standard curve for adenosine and thymidine were all

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

Bulbus of Fritillaria delavayi Franch. is the most commonly used antitussive and apophlegmatic in China and commonly prepared by water decoction. In this study, a novel and reliable method of high-performance liquid chromatography (HPLC) was developed both for quantitative analysis of 10 bioactive

Three compounds were isolated from stems and leaves of Fritillaria ussuriensis. They were identified as adenosine, galacitiol and succinic acid.

OBJECTIVE To develop a high performance liquid chromatography coupled with a photodiode array detector (HPLC-DAD) method for simultaneous determination of 7 nucleosides and nucleobases in Fritillaria taipaiensis. METHODS The analyses were performed on an Agilent Zorbax-SB-Aq-C18 column (4.6 mm x 250

Based on platelet aggregation induced by platelet activating factor (PAF), the active fraction with inhibiting effect was screened from four species of Chinese drung Beimu, the bulbs of Fritillaria przewalskii, F. ussurienis, F. anhuiensis and F. thunbergii. According to the experimental results,

A sensitive and reliable HPLC-diode-array detector method was developed for the first time to simultaneously determine nine nucleosides and nucleobases including uracil, cytidine, guanine, uridine, thymine, inosine, guanosine, thymidine and adenosine in 13 different Fritillaria species. The analysis
