Determination of γ-Aminobutyric Acid in Pinellia ternate(Thunb.)Breit.at different Growth Stages


  [Objective] To establish a method for determing γ-aminobutyric acid in the Pinellia ternate(Thunb.)Breit..[Method] γ-aminobutyric acid in the Pinellia ternate(Thunb.)Breit.at different growth stages was determined by TLC.[Result] The content of γ-aminobutyric acid and peak area were in good linear relationship in the range of 0-1.0 mg/ml(r=0.998 1),the average recovery rate was 95.6%,RSD was 4.12%.The content of γ-aminobutyric acid in Pinellia ternate(Thunb.)Breit.was 0.143% in early May.[Conclusion] The best harvest time of Pinellia ternate(Thunb.)Breit.is the first ten days of May.……
