Abstract:
Objective To develop a sensitive and reliable RP-HPLC method for the simultaneous determination of nine nucleosides including uracil, cytidine, guanine, uridine, adenine, guanosine, thymidine, adenosine and 2'-deoxyadenosine from Fritillaria taipaiensis P. Y. Li that had been cultivated in different producing areas; To compare the contents of these nucleosides from different producing areas. Methods The analysis was performed on a Venusil MP C18 (2) column (4.6 mm×250 mm, 5 μm) with a gradient of methanol-water at a flow rate of 1.0 mL/min;the detective wavelength was set at 260 nm; the column temperature was set at 35 ℃. Results Uracil, cytidine, guanine, uridine, adenine, guanosine, thymidine, adenosine and 2'-deoxyadenosine were obtained in the good linear range of 0.269 5–16.17 μg/mL, 0.132 1–7.927 5 μg/mL, 0.095 5–5.73 μg/mL, 1.16–69.6 μg/mL, 0.48–28.8 μg/mL, 0.571 5–57.15 μg/mL, 0.526–52.6 μg/mL, 3.307 5–198.45 μg/mL, 0.530 5–31.83 μg/mL, respectively (r≥0.999 5);the recovery was in the range of 96.49%–101.65%(RSD≤2.92%). Conclusion The contents of the nine nucleosides from different producing areas have differences. Fritillaria taipaiensis P. Y. Li from Xianyi Village, Chengkou County, Chongqing City, whether the cultivated ones or wild ones, contain the highest level of nucleosides. The established method can provide references for the perfection of quality standard for Fritillaria taipaiensis P. Y. Li.
