The article analyzes change of its ingredients including Ca(superscript 2+), Fe(superscript 2+) 42(superscript 2+) within different process using chemical analysis, iodine amount and testing chemical value ,and prove the conclusion that the method abouve is one of the best ways to process ruddle through experimental data, which may cause ruddle crispy and easy to be smashed, and get the effctive ingredients, and arsenic's amount can be limited as the value require by codex (0.01%).

利用化学分析法、碘量法以及化合价数的测定法来分析代赭石不同炮制品中的Ca(上标 2+)、Fe(上标 2+)、As(上标 3+)的含量变化，通过实验数据来证实煅醋淬法是炮制代赭石最行之有效的一种理想方法，会使代赭石质地最酥脆，易于粉碎，使有效成份最易煎出，最能使炮制品中冲的含量(0.01%)符合药典要求，建议把砷的含量作为股代赭石的一个质量指标。

Notably, a low dose of D. salina extract was sufficient to aggravate As2O3-induced cytotoxicity in HL-60 cells.
