目的:探讨不同炮制方法对紫硇砂中硫含量的影响。方法:采用紫外分光光度法在276 nm处测定紫硇砂生品及其3种不同炮制品中硫的含量。结果:硫在1～30μg·ml~(-1)浓度范围内具有良好的线性关系(r=1.000 0),平均回收率为101.09%,RSD=2.37%(n=6)。紫硇砂生品中硫的含量为111.05μg·g~(-1),3种不同炮制品中硫的含量分别为:水煮法为14.37μg·g~(-1),隔水醋制浮霜Ⅰ法为21.11μg·g~(-1),隔水醋制浮霜2法为36.90μg·g~(-1),直火醋制法为42.40μg·g~(-1)。结论:紫硇砂隔水醋制浮霜2法炮制品和直火醋制炮制品中硫的含量显著低于生品,但明显高于水煮法炮制品,这可能与降低紫硇砂的毒性,又保留紫硇砂治疗作用有一定的关联性。
Objective: To investigate the effect of different processing methods on the sulfur content of aster sand. Methods: The content of sulfur in Aspergillus sand products and three kinds of processed products were determined by UV spectrophotometry at 276 nm. RESULTS: Sulfur had a good linearity (r = 1.000 0) within the range of 1 ~ 30 μg · ml -1 with an average recovery of 101.09% and a RSD of 2.37% (n = 6). The content of sulfur in the products of Aster sand was 111.05μg · g -1, the content of sulfur in the three kinds of processed products was 14.37μg · g -1 by boiling method, The method of defrosting Ⅰ was 21.11 μg · g -1, the method of defrosting with vinegar was 36.90 μg · g -1, and the method of direct fire vinegar was 42.40 μg · g -1. CONCLUSION: The content of sulfur in asbestos-sand-control vinegar-made cream-frost-2 and direct-fire vinegar-made products was significantly lower than that of raw products, but significantly higher than that of boiled-dried products, Toxicity, and retain the role of Aster sand treatment has a certain relevance.
