白芷的产地盐水腌制干燥技术分析

目的:采用盐水腌制干燥技术,使新鲜的白芷在产地快速干燥,避免腐烂和霉变,获得一种白芷药材。方法:取稍蔫的新鲜白芷,除去泥土,整齐地放置在容器中,用压石压住,加入盐水,浸过白芷,腌制1~2 d,将预处理的盐水倒出,加入与预处理时几乎等量的盐水,密封,腌制一段时间,取出白芷,用水反复浸泡和淋洗,晾干,即可获得白芷药材。结果:采用盐水腌制法加工的白芷中指标成分、醇溶性浸出物含量等指标均达到了2015年版《中国药典》对白芷药材的质量规定,所有样品中亚硝酸盐质量分数均低于3.3 mg·kg-1(检测限),符合盐渍品中亚硝酸盐的限量指标。结论:在产地采用盐水腌制法获得的药材白芷,在简易仓库中贮藏2年未见变质现象,为中药白芷的产地加工提供了一条新技术。

Aanlysis of Saline Water Salting and Drying Technology of Angelicae Dahuricae Radix

Objective:To develop a saline water salting and drying technology for obtaining the medicinal materials of Angelicae Dahuricae Radix(ADR) in place of origin and avoiding rot and mildew. Method:The slightly wilted fresh ADR was tiled in a container,immersed in the saline water,pressed with stone on the surface,pickled for 1-2 d,discard the saline water,added almost equal amount of fresh saline water,pressed with stone on the surface again,sealed,pickled for a period of time,picked up,soaked and rinsed with water,put in a cool ventilated place to dry,and obtained the medicinal materials of ADR. Result:The medicinal materials of ADR processed by saline water salting and drying technology met all stipulation in the 2015 edition of Chinese Pharmacopoeia about ADR,and the content of nitrite in all samples was lower than 3.3 mg·kg^-1(detection limit),which was in line with the limit index of nitrite in salted products. Conclusion:A new saline water salting and drying technology is developed to make medicinal materials of ADR in place of origin,and no metamorphism has been observed for 2 years later stored in simple warehouse.
