中文摘要 | 藥材之療效,與其所含之微量元素有密切的關係,為加速中藥之科學化,有探討研究的必要。本計畫擬從微量元素分析的觀點,探求植物藥材中所含微量元素之種類及含量與規格之關係。由於藥材中所含元素大都屬微量,且藥材基質申有其他有機成分會造成干擾,因此須有相當純熟的分析技術以達到準確性和精密度規範。本計畫的目的之一,即在發展藥材中微量元素的標準分析方法。本計畫目標:在學術上,1. 發展高靈敏及高準確之微量元素分析方法。2. 側定植物藥材中七種微量元素之含量,以作為臨床上用藥的參考標準。在實用上,建立國內檢驗植物藥材中微量元素的分析能力。本年完成的工作項目:1. 蒐集國內外相關文獻:銅、汞、鎘、鉛、砷、錳及鈷之規格與分析方法。2. 各子計畫執行單住所用來進行研究之各種藥材之基源、產地確認。植物性藥材為: 黃耆、黨參、甘草、茯苓、當歸;動物性藥材為:蛤蚧、龜板、鱉甲、阿膠、海馬; 礦物性藥材為:龍骨、赤石脂、禹餘糧、自然銅、石膏;科學成方中藥為:小柴胡湯、大柴胡湯、補中益氣湯、加味逍遙散、龍膽瀉肝湯。其中科學成方中藥不做基源、產地確認。3. 探討黃耆、黨參、甘草、茯苓、當歸等五種藥材最佳之取樣方法及使用硝酸於加熱板迴流式或微波消化爐兩種消化方法,最佳消化條件探討。4. 探討感應耦合電漿原子發射光譜法測定銅、汞、鎘、鉛、神、錳及鈷含量之最佳分析條件。5. 建立分析之QA/QC系統,針對干擾效應、基質效應、精密度、準確度(CRM樣品分析)及回收率,做確認。 |
英文摘要 | The medical efficiency of natural drugs is closely related to the nature contents of trace elements. For accelerating scientification of Chinese medicine, it is necessary to study further from different point of views. This project is therefore dealing with the concentration of trace elements in different species and the specification of the Chinese herb natural drugs. The concentration of elements in natural drugs is usually very low; therefore, achieving a precise and accurate analysis result must be accompanied with a proficient technique. Particularly, the interference problems of matrix effects make analytical works more difficult and complicated. The main purpose of this project is to provide the method on trace elements analysis with high accuracy and precision for natural drugs. The major works of this project have been accomplished as followed: 1. to establish and verify the characteristic identity of various Chinese drugs applied by this whole project, i.e., animal based: Gekko gecko L., Chinemys reevesii (Gray), Trionyx sinensis Wicgmann, Equas asinus L., Hippocampus kalloggi Jordan et Snyder, herb based: Astragalus membranaceus Bge. var. mongholicus (Dge.) Hsiao, Codonopsis pilosula (Franch.) Nannf., Glycyrrhiza uralensis Fisch., Poria cocos (Schw.) Wolf, Angelica sinensis (Oliv.) Diels., mineral based: Os Draconis, Halloysitum Rubrum, Limonitum, Pyritum, gypsum Fibrosurn, and Traditional Chinese Medicine Presciptions: Xiao chai hu tang, Da chai hu tang, Bu zhong yi qi tang, Jia wei xiao yao san. Long dan xie gan tang. 2. to do the literature survey on the specification and the analytical method of herb natural drug for copper, mercury, cadmium, lead, arsenic, manganese and cobalt. 3 .to establish the optimal sampling and digestion technique for Chinese herb natural drugs. 4. to set up the optimal analytical conditions for the determination of the concentration of copper, mercury, cadmium, lead, arsenic, manganese and cobalt by ICP-AES. 5. to check the QA/QC system in terms of interference, matrix effects, precision, accuracy of CRM, and spike recovery. |
