Correlation study on high performance liquid chromatography and antidepressant effect of different eluting fractions of acorus tatarinowii schott macroporous resin / 重庆医学

ABSTRACT

Objective To research the correlation on high performance liquid chromatography (HPLC) and antidepressant effect of different elution fractions of acorus tatarinowii schott macroporous resin .Methods Prepared different fractions by using AB‐8 macroporous resin .Establish HPLC characteristic chromatograms of crude drugs and different elution fractions from AB‐8 acorus tatarinowii schott macroporous resin by using gradient elusion .Confirm characteristic peaks in chromatograms .despair mod‐els of male mice ,including tails suspension test (TST ) ,forced swimming test (FST ) were used to evaluate antidepressant effects by taking orally .Results HPLC chromatograms of crude drugs and different fraction of acorus tatarinowii schott showed that they had same characteristic peaks .Elution of 90% and 70% alcohol solution from AB‐8 macroporous resin can obviously reduce TST and FST time .The anti‐depressant effect were associated with characteristic peaks on chromatogram .Conclusion Acorus tatarinowii schott has anti‐depressant effect ,and mainly from 70% and 90% alcohol solution eluted from AB‐8 macroporous resin .HPLC char‐acteristic chromatography and data relationship between relative peaks can be used to judge the antidepressant effects of acorus ta‐tarinowii schott ,and give reference to research and product development .
