摘要
目的：对藏药＂渣驯＂进行物质组成研究,为阐释其来源提供依据,并为建立质量标准提供参考。方法：采用生药学常规方法进行药材性状及显微鉴别,采用电感耦合等离子体光谱法测定26种矿物元素,采用X射线衍射法分析结晶物相,参照GB/T 14610-2008测定钙的含量,参考《土壤分析技术规范》测定有机质含量,参照GB/T11957-2001测定腐殖酸含量,采用容量滴定法测定黄腐酸含量,参照2010年版中国药典测定水分、灰分、酸不溶性灰分、水溶性浸出物。结果：渣驯药材中普遍含有动物粪便,结晶物相主要为Si O2,26种矿物元素含量总和约3%,13批次药材中有机质含量为29.03%~71.79%,腐殖酸含量为28.37%~58.51%,黄腐酸含量为19.69%~41.43%,水分为5.2%~11.7%,灰分为17.82%~64.39%,酸不溶性灰分为2.10%~39.09%,水溶性浸出物含量为28.39%~57.40%。结论：认为有关渣驯来源于金属熔汁的传统记载缺乏科学依据,渣驯中的矿物元素以非晶形存在;渣驯中含有大量有机质,包括腐植酸和黄腐酸;无机物中部分来源于泥沙;岩层中的有机质经历了漫长的地质演化。
Objective：To study the material composition of Tibetan medicine ＂Brag-zhun＂, and to provide the basis for interpreta- tion of its source and reference for the establishment of quality standards. Methods ： Pharmacognosy routine method was used in macro- scopic and microscopic identifications, inductively coupled plasma spectrometry was carried out to determine 26 kinds of mineral ele- ments, and X-ray diffraction analysis was used for the crystalline phase detection of Brag-zhun. The content of calcium, organic matter, humic acid and fulvic acid was determined according to GB/T 14610-2008,＂ technical specification for soil analysis＂, GB/T 11957- 2001 and capacity titration, respectively. Moisture, ash content, acid insoluble ash content and water soluble extract were determined with reference to the Chinese Pharmacopoeia（2010 edition）. Results：Animal feces were commonly found in Brag-zhun,the main crystal phase was SiO2 ,26 kinds of mineral elements content in total was about 3%, 13 batches of medicinal materials in organic matter content was 29. 03% ~ 71.79%. Humic acid content was 28.37% -58.51% ;fulvic acid content was 19. 69% ~ 41.43% ;moisture was 5.2% 11.7% ;total ash content was 17. 82% -64. 39% ;acid insoluble ash content was 2. 10% -39.09% ;and water soluble extract was 28.39% - 57.40%. Conclusion ： The traditional record of Brag-zhun from molten juice is lack of scientific basis. The mineral elements in Brag-zhun exist in amorphous. Brag-zhun contains a lot of organic matter including humic acid and fulvic acid, and inorganic matter mainly comes from sediment. The organic matter in rock has gone through a long geological evolution.
