Identification of Quality Goods and Adulterants of Traditional Chinese Medicine Lygodium japonicum(Thunb.)Sw by FT-IR
摘要
Abstract
[Objective] The research aimed to identify quality goods and its adulterant of traditional Chinese medicine Lygodium japonicum by FT-IR method.[Method] Under the right conditions (spectral range:4000-400 cm-1;resolution:4 cm-1;transmittance:0-100%;sweep frequency spectrum:32 times;speed:0.6329 cm/s;detector:DTGSKBr;Thermo scientific EZ OMNIC instrument system operating software;spectrum correction:water and carbon dioxide;background spectrum management:sampling samples before background) using FT-IR to measure the infrared absorption spectrums of Lygodium japonicum samples and its adulterant,and then compare them.[Result] The infrared spectra of each sample of Lygodium japonicum were basically the same.There were obvious difference between infrared spectra of quality goods and its adulterants.The precision,repeatability and stability test of the experimental method were qualified.[Conclusion] This method is simple and accurate and could use to identify quality goods and its adulterants of Lygodium japonicum.关键词
