目的:检测不同生长时期温莪术中常量与微量元素变化规律,为药源的开发和利用提供依据。方法:采用微波消解,利用电感耦合等离子体原子发射光谱法(ICP-AES)及原子吸收分光光度法(AAS)测定温莪术11种常量与微量元素,并用主成分投影方法对不同生长时期样品的金属代谢模式进行分析。结果:显示温莪术中Ca、Mg、Mn、Cu和Zn元素等元素含量较丰富,在考察的生长时期内温莪术中Cu积累量基本保持不变,但Ni、Fe积累量波动较大,此外莪术中还存在微量的元素Se。主成分分析表明,温莪术中金属物质代谢可以分为二类模式。结论:该法为探讨温莪术无机元素的积累关系及进一步研究温莪术元素与生长状态的关系提供了依据。
OBJECTIVE: To detect the regularity of variation in constants and trace elements in Wenqi surgery at different growth stages to provide basis for the development and utilization of drug sources. Methods: Microwave ablation was used to determine the 11 kinds of constants and trace elements of Indoleum aurantii by inductively coupled plasma atomic emission spectrometry (ICP-AES) and atomic absorption spectrometry (AAS), and the principal component projection method was used to analyze the samples of different growth stages. Metal metabolism patterns are analyzed. RESULTS: The results showed that Ca, Mg, Mn, Cu and Zn elements were rich in genital warts. Cu accumulation during warming phlegm in the study period remained basically unchanged, but the accumulation of Ni and Fe fluctuate greatly. There are also trace elements Se in the curcuma. The principal component analysis showed that the metabolism of metal substances in Wen Zhen surgery can be divided into two types of models. Conclusion: This method provides a basis for exploring the relationship between the accumulation of inorganic elements and the relationship between the elements of Gentian and growth status.
