Abstract
Objective:To establish the method for determination of luteolin in Caulis et Folium Stauntoniae.Method: The chromatographic conditions was as follows: a Dikma Diamonsil C18(4.6 mm×250 mm
5 μm) column
a mobile phase of acetonitrile-0.1% H3PO4(26∶74);and a UV detector at 350 nm.Result: Luteolin was linear in the ranger of 0.067 75-2.168 μg(r=0.999 9);the average recovery of 99.25%(RSD 1.65%)
the precision with RSD 2.22%
repetition with RSD 1.24% and stability with RSD 2.58% were obtained.Conclusion: The method is accurate
reliable
and can be used for quality control of the production.
