摘要
【目的】分析比较印尼、印度以及澳洲产檀香的氨基酸图谱。【方法】采用氨基酸自动分析仪分别对3产地檀香的游离氨基酸及水解氨基酸进行分析,检测波长为570 nm、440 nm。【结果】3产地檀香游离氨基酸图谱具有明显差异,印尼檀香在11.77 min(λ=440 nm)检测到2S,4S-4-羟脯氨酸峰,含量约1.431 7%,水解后为脯氨酸,而印度、澳洲檀香此峰极弱或未检测到。【结论】3产地檀香的游离氨基酸图谱具有明显差异,2S,4S-4-羟脯氨酸可以作为区别3种檀香的特异性鉴别成分。
[Objective] To compare the fingerprint spectrum of amino acids （AA） of Lignum Santali Albi （LSA） from Indonesia, India and Australia. [Methods] Free AA and hydrolytic AA of LSA from Indonesia, India and Australia were analyzed by amino acid automatic analyzer. The detection wavelength was 570nm and 440nm. [ Results] There were obvious differences among the free AA from three kinds of LSA. 2S, 4S-4-hydroxyproline （Hyp） was detected in Indonesian LSA in 11.77min （λ = 440nm） with the content of 1.431 7%, and became proline after hydrolysis. The peak of Hyp was not obvious or even undetectable in Indian LAS and Australian LSA. [Conclusion] There exist obvious differences among free AA from three kinds of LSA and 2S, 4S-4-Hyp can be used as the specific compounds for the identification of LSA from Indonesia, India and Australia.
