摘要：本實(shí)驗(yàn)以三七、茯苓、黃連、重樓和木香為材料，通過(guò)不同干灰法條件（溫度、時(shí)間）對(duì)這五種中草藥進(jìn)行處理，然后用石墨爐原子吸收光譜法測(cè)定樣品中微量元素Cu的含量。三七的最佳灰化條件:時(shí)間6小時(shí),溫度550℃；茯苓最佳灰化條件:時(shí)間4小時(shí),溫度400℃；黃連最佳灰化條件:時(shí)間4小時(shí)，溫度550℃；重樓最佳灰化條件:時(shí)間4小時(shí)，溫度550℃；木香最佳灰化條件:時(shí)間6小時(shí),溫度550℃。干法灰化條件下石墨爐原子吸收光譜法有效測(cè)定三七等五種中草藥中Cu含量，操作簡(jiǎn)便、快捷。三七、茯苓、重樓、黃連和木香這五種中草藥中測(cè)定銅含量各有差異，黃連中Cu含量是茯苓的2倍，從大到小順序?yàn)辄S連、三七、木香、重樓、茯苓，它們中銅測(cè)定結(jié)果都低于20. 0 mg/kg。 關(guān)鍵詞：石墨爐原子吸收光譜法；中草藥；灰化條件;銅
ABSTRACT：This experiment to notoginseng, tuckahoe, rhizoma coptidis, heavy floor and combination for material, through different dry ash method conditions (temperature, time for the five kinds of Chinese herbal medicine processing, then use graphite furnace atomic absorption spectrometric determination of trace element in the sample the content of Cu. The conditions of the best ash notoginseng: time six hours, temperature 550℃; Poria cocos best grey change conditions: time four hours, temperature 400℃; Coptis chinensis franch of conditions: time best ash temperature 4 hours, 550℃ ; Heavy floor of conditions: time best ash temperature 4 hours, 550℃ ; Combination of conditions: time best ash temperature 550℃, 6 hours.Under the conditions of dry ash graphite furnace atomic absorption spectrometry effective determination in five Chinese herbal medicine notoginseng Cu content, and operate simple, quick. Sanqi (panax notoginseng), tuckahoe, heavy floor, rhizoma coptidis and combination of these five kinds of Chinese herbal medicine copper content determination, coptis chinensis franch have difference each Cu content is in the 2 times, from has to small order of rhizoma coptidis, notoginseng, woody, heavy floor, tuckahoe, they copper determination result below 20. 0 mg/kg.
