1. 抗菌作用 体外实验表明：醇提取物对革兰阳性细菌如金黄色葡萄球菌、

1. In vitro experiments showed antibacterial effect: ethanol extract of gram-positive bacteria such as Staphylococcus aureus inhibitory effect, pneumococcus, diphtheria bacillus so on, its role and potassium penicillin 20 units / ml similarity; Gram-negative bacteria the inhibitory effect also Bacillus subtilis, E. coli, Vibrio cholera and typhoid bacillus, paratyphoid bacillus, dysentery bacillus, its role and streptomycin sulfate 50 units / ml similarity; bacteriostatic effect on fungi than 1% benzoic acid and salicylic acid. <br>2. antihistaminic ethanol extract (1:50) isolated guinea pig trachea antihistaminic activity, its role fast, strong and long-lasting.

1. Antibacterial effect In vitro experiments show that: alcohol extract on gram-positive bacteria such as Staphylococcus aureus, pneumococcus, leukado, etc. have a antibacterial effect, Its effect is similar to penicillin potassium salt 20 units/ml, and also has a antibacterial effect on gramnegative bacteria such as hercobacterium, E. coli, Vibrio cholerae and typhoid bacteria, paratyphoid bacteria, dysentery bacteria, etc., and its effect is similar to 50 units/ml of staccatoin sulfate, and the antibacterial effect on fungi is greater than 1% of benzoic acid and salicylic acid.<br>2. Antihistamine action Ethanol extract (1:50) has antihistamine effect on the exosome guinea pig trachea, which acts fast, strong and long-lasting.

1. In vitro antibacterial experiment showed that the alcohol extract had antibacterial effect on Gram-positive bacteria such as Staphylococcus aureus, pneumococcus, diphtheria, etc., which was similar to penicillin potassium salt 20 units / ml; it also had antibacterial effect on Gram-negative bacteria such as Bacillus subtilis, Escherichia coli, arc cholera and typhoid, paratyphoid and dysentery, Its effect is similar to that of streptomycin sulfate (50 units / ml); its bacteriostatic effect on fungi is greater than 1% benzoic acid and salicylic acid.<br>2. Antihistamine effect ethanol extract (1:50) has antihistamine effect on isolated guinea pig trachea, which is fast, strong and lasting.
