摘要
目的:对傣药"坡扣"(天南星科植物大千年健Homalomena gigantea Engl.的干燥根茎)及其水浸炮制品的不同提取部位进行红外光谱(IR)比较鉴定研究,为该药的深入研究及推广应用提供进一步的鉴定参考依据。方法:利用红外光谱法比较并研究"坡扣"样品炮制前后不同提取部位的鉴别特征。结果:"坡扣"药材(切片生品)与炮制品两者的石油醚提取部位红外光谱无明显差异,乙酸乙酯提取部位的红外光谱有显著不同,正丁醇提取部位的红外光谱也有一定差异,并初步分析了炮制前后引起红外光谱变化的化学基础。结论:研究结果为该品的研究及应用提供了红外光谱鉴定参考依据。
Objective：To study identification methods of different extracts of Dai Medicine ＂Pokou＂（the rhizome of Homalomena gigantea Engl.） and its processed product made by immersing it in water,and provide reference for identification of the drug in further researches and applications.Methods： FTIR technique was used for identifying the features of different extracted parts of this crude drug and its processed product.Results： Compared with the crude drug,the petroleum ether-extracted parts of processed product turned out to have no obvious distinction in the FTIR.There was a large difference in the ethyl acetate-extracted parts,and the n-butanol-extracted parts also had certain discrepancy.A preliminary analysis was made on the chemical fundamentals which caused the changes in the FTIR before and after the drug′s processing.Conclusion： The results provide an infrared spectral identification method for the drug and its applications.
