三七药材表面多皱缩,带有大量的细菌,往往不易处理干净,因而也使得成药极难达到药品卫生标准。γ-射线对三七粉的灭菌效果较为理想,但此种方法一般小厂难以采用。我们实验发现,高压酒精蒸汽对三七粉的灭菌效果也很理想,值得研究。一、实验方法和结果将南城制药厂生产的三七粉用盘子盛好置直立式热压灭菌器内室(盘底应有细小的圆形小洞,用纱布盖住小洞,药粉置纱布上,这样有利酒精蒸汽的渗入)。粉末厚度约2cm。自漏斗中加入
Sanqi medicinal materials are shrinking on the surface, with a large number of bacteria, and they are often not easy to handle. Therefore, it is extremely difficult for medicines to meet the standards of pharmaceutical hygiene. The bactericidal effect of γ-rays on Sanqi powder is ideal, but this method is generally difficult for small factories to adopt. Our experiments showed that the sterilization effect of high-pressure alcohol vapor on Panax pseudoginseng powder is also very satisfactory and worthy of study. I. Experimental methods and results The Panax notoginseng powder produced by the Nancheng Pharmaceutical Factory was used to hold the interior of the vertical autoclave sterilizer. There should be small round holes in the bottom of the pan, and the small holes should be covered with gauze. On the gauze, so that the penetration of alcohol vapor is favorable). The powder thickness is about 2cm. Join from funnel
