用ICP-AES测定陕西汉中市中药姜黄中的2种常量营养性元素(钙、镁)和5种微量元素(铜、铬、铁、锌、锰)含量。钙6010.5μg.g-1、镁6250.1μg.g-1、铜18.8μg.g-1、铬4.2μg.g-1、铁331.8μg.g-1、锌208.6μg.g-1、锰477.4μg.g-1,加标回收率均在96.4%—102.5%之间,结果表明,此方法简便、可靠,具有良好的精确度和准确性。并初步讨论了中药姜黄中有益营养性元素与治疗疾病的关系,汉中中药材姜黄无机元素因地域不同,元素含量略有差异。
The contents of two kinds of macronutrients (calcium and magnesium) and five kinds of trace elements (copper, chromium, iron, zinc and manganese) in turmeric of Hanzhong City in Shaanxi Province were determined by ICP-AES. Calcium 6010.5 μg.g -1, Magnesium 6250.1 μg.g -1, Copper 18.8 μg.g -1, Chromium 4.2 μg.g -1, Iron 331.8 μg.g -1, Zinc 208.6 μg.g -1, Manganese 477.4 μg.g-1, the spiked recoveries were between 96.4% -102.5%, the results show that this method is simple and reliable, with good accuracy and accuracy. The relationship between beneficial nutrition elements in Chinese traditional medicine turmeric and the treatment of diseases was also discussed.
