[Determination of total scopoletin in Caulis Erycibes by RP-HPLC].
OBJECTIVE
To accumulate data for quality control of Caulis Erycibes.


METHODS
The total-scopoletin in Caulis Erycibes was determined by RP-HPLC, using CLC-ODS1 column, 0.5% glacial acetic acid in methanol-water(26:55) as mobile phase and UV detector at 310 nm.


RESULTS
The average recovery is 99.37% and RSD 0.39%.


CONCLUSIONS
Determination data have been obtained for fourteen batches of three species, and the contents of scopoletin should be no less than 30 mg/100 g.
