为了说明白花蒿在临床上治疗喘息型慢性支气管炎患者有一定的疗效,我们将其分离提取的挥发油及有效成分白花蒿醇用常规方法作抑菌试验。实验结果表明完全抑制6种细菌的最低药物浓度,白花蒿醇 0.05mg/ml,白花蒿挥发油为0.2mg/ml(见表1)。以2mg/ml的白花蒿挥发油、白花蒿醇与1u/ml浓度的青霉素、硫酸链霉素比较,其作用强度相近似,均具有统计学意义。 In order to demonstrate that Artemisia annua has certain curative effect in clinical treatment of patients with asthmatic chronic bronchitis, we extracted the volatile oil and effective ingredient of artemisinin by conventional methods for bacteriostasis test. The experimental results showed that the minimum drug concentration of 6 kinds of bacteria was completely inhibited, that is, the artemisinin 0.05 mg/ml, and the volatile oil of Artemisia annua 0.2 mg/ml (see Table 1). Compared with 2 mg/ml Artemisia annua Volatile oil and Artemisinin, and 1u/ml penicillin and streptomycin sulfate, the effects were similar and all had statistical significance.
