摘要：有機(jī)氯-六六六的提取和檢測是用科學(xué)的方法從中藥材中提取出有機(jī)氯-六六六及檢測出有機(jī)氯-六六六在中藥材中的含量的過程。本畢業(yè)論文采用超聲提取、氣相色譜檢測法對云黃連中有機(jī)氯-六六六含量的提取與測定。得出最佳超聲提取的最佳料液比為1：15，最佳超聲功率為40KHZ,90%，最佳超聲時間為15min，最佳超聲次數(shù)為2次,平均回收率得出γ-666的回收率偏高，δ-666的回收率偏低，α-666一般。從精密度得出儀器的穩(wěn)定性良好，從重現(xiàn)性得出此方法的穩(wěn)定性良好。 關(guān)鍵詞：云黃連；有機(jī)氯-六六六；超聲提??；氣相色譜法
ABSTRACT：Organochlorine - 666 extraction and detection is used the scientific method to extract medicinal powder high-powerdorganic chloride-containing powder - 666 and detect the 666 in Chinese herbal medicine powder high-powerdorganic chloride-containing powder - the content of process. The graduation thesis intends to by ultrasonic extraction, gas chromatography assay on cloud of rhizoma coptidis 666 content of organic - extraction and determination. Obtains the best of the best material ultrasonic extraction liquid ratio for 1:15, best speeding 40KHZ, 100%, optimum ultrasound time for 15min, optimum ultrasound times average recovery for 2 times, that the recovery of gamma - 666 delta - high recovery is low, 666 alpha 666 generally. The stability of the obtained from precision instrument from reproducibility good, that this method is good stability.
