Objective: To develop an HPLC method for the simultaneous determination of three constituents about isofraxidin
lasianthuslactone and codonolactone. Method: The separation was performed on a Hypersil C18 column (4.6 mm×250 mm
5 μm) eluted with acetonitle and 0.1% phosphoric acid solution as mobile phase in a linear gradient mode. The flow rate was kept at 1 mL·min-1and the column temperature was set to 30℃
the UV detector wavelength was set at 230 nm. Result: The linear ranges were 2-100 ng for isofraxidin
2-100 ng for lasianthuslactone
4-200 ng for codonolactone
and the three components had a good linear relationship (r>0.999). Result of three components recovery tests were 96.1% (RSD 2.3%)
94.4% (RSD 2.0%)
94.2% (RSD 1.9%). The content of isofraxidin is more in Chloranhus multistachy
it is 18 μg·g-1;the codonolactone and lasianthuslactone were higher in C. fortumei
