Analysis of non-alkaloids from radix sophorae tonkinensis by GC-MS / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the chemical compositions and their contents in non-alkaloids fraction from Radix Sophorae Tonkinensis.</p><p><b>METHOD</b>The non-alkaloids from Radix Sophorae Tonkinensis were analyzed by gas chromatography/mass spectrometry after trimethylsilyl derivatization. The chemical compositions were identified by comparison of the authentic sample and NIST database; the contents of 19 identified components were determined by linear regression equation.</p><p><b>RESULT</b>19 compounds constituting 34.72% of the non-alkaloids were identified. The major components were saccharides (5 compounds constituting 22.62%), organic acid (9 compounds constituting 11.81%), and others (5 compounds constituting 0.29%).</p><p><b>CONCLUSION</b>The GC-MS is a simple, rapid and sensitive method to investigate the complex primary metabolites in plants.</p>
