ObjectiveTo determine rutin in buds of Tussilago farfara L.

目的研究巫溪不同产地的款冬所含的芦丁的差异。

The extraction and stability of the pigments in Tussilago farfara L. were studied. The experimental results showed that the pigments could be solved in acetone. The stability of the pigments is good when pH is within 3~9; the oxidizing agents, reducing agents and common food additives have little influence on its stability; it is react too much with Fe(superscript 3+) ion, and Na(superscript +) ion showed a certain increment effect on the color; the heat performance of the pigments is good when under 60℃.
