摘要
用80%酒精提取番石榴叶中的有效成分, 观察提取物对细菌和离体小肠的作用。结果表明: 提取物能抑制大肠杆菌等6种病原菌生长; 降低家兔十二指肠、空肠、回肠等三肠段收缩张力。
Dried ground leaves of Psidium guajava L were extracted with 80% aqueous ethyl alcohol, and the effects of this extract on bacteria and small intestine contraction were determined in vitro. The results showed that the guava sprout extract could inhibit six species of the bacteria at the concentrations of 1 g/mL, and also decrease spontaneous contractions of rabbit small intestine at the concentrations of 10 mg/mL.
