[Objective] To determine the contents of amino acids in flower of Lilium brownii var.viridulum.[Method] Contents of 17 amino acids in flower of Lilium brownii var.viridulum were determined using OPA-HPLC method,in which o-phthalaldehyde(OPA)and 9-fluore-nylmetloy chorofomnate(FMOC)were selected as pre-column derivative reagent and VWD detector was used.[Result] The Lilium brownii var.viridulum from Shaoyang was rich in Asp,Glu,Ser,His,Gly,Thr,Arg,Ala,Tyr,Cys,Val,Met,Phe,Iso,Leu,Lys and Pro.The contents of essential amino acids for adult and for children were 49.7 and 30.6 mg/g,respectively,which were 31.20% and 19.20% of total contents of amino acids individually.Content of Glu and Arg in samples ranked the first and second,respectively,which were 28.7 and 27.5 mg/g respectively,taking up 18.03% and 17.30% of total amino acids.[Conclusion] The method does not require proprietary analyzers and is simple in operation,high in accuracy and accurate in determining result.Flower of Lilium brownii var.viridulum is rich in amino acids,which is of high developing value.
[Objective] To determine the contents of amino acids in flower of Lilium brownii var. Viridulum. [Method] Contents of 17 amino acids in flower of Lilium brownii var. Viridulum were determined using OPA-HPLC method, which o-phthalaldehyde (OPA ) and 9-fluore-nylmetloy chorofomnate (FMOC) were selected as pre-column derivative reagent and VWD detector was used. [Result] The Lilium brownii var. viridulum from Shaoyang was rich in Asp, Glu, Ser, His, Gly, Thr , Arg, Ala, Tyr, Cys, Val, Met, Phe, Iso, Leu, Lys and Pro.The contents of essential amino acids for adult and for children were 49.7 and 30.6 mg / g, respectively, which were 31.20% and 19.20 % of total contents of amino acids individually. Content of Glu and Arg in samples ranked the first and second, respectively, which were 28.7 and 27.5 mg / g respectively, taking up 18.03% and 17.30% of total amino acids. method does not require unique analyzers and is simple in operation, high in accuracy and accurate in determining result. Flow of Lilium br ownii var.viridulum is rich in amino acids, which is of high developing value.
