栽培忍冬茎叶活性成分含量测定及其抑菌活性研究
Determination of Content of Active Constituents in the Stems and Leaves of Cultivated Lonicera japonica Thunb.and Their Antibacterial Activities
摘要
Abstract
In order to study the medicinal value of the stems and leaves of cultivated L. Japonica, and the antibacterial activity of the crude extracts,this paper determinated the effective constituents in the stems and leaves, the flower of the cultivated and wild L. Japonica. The antibacterial activities against seven common bacteria from different extraction of crude extracts of the stems and leaves of cultivated L. Japonica were studied by the filter paper method. The results showed that total phenol,flavonoids and total soluble sugar in the stems and leaves of cultivated L. Japonica were 12. 74 mg/g,21. 64 mg/g and 77. 40 mg/g, respectively. The order of the content of total phenol was the stems and leaves of cultivated L. Japonica < the flower of the wild L. Japonica-^ the flower of the cultivated L. Japonica; the order of the content of flavonoids was the flower of the wild L. Japonica<^the stems and leaves of cultivated L. Japonica<Cthe flower of the cultivated L. Japonica; the order of the content of total soluble sugar was the flower of the wild L. Japonica<I the flower of the cultivated L. Japonica<^the stems and leaves of cultivated L. Japonica. The antibacterial activity of the ethyl acetate extraction part of ethanol extracts against Phytophthora capsici ,Fusarium oxysporum. F sp. Cucumerinum and Staphylococcus aureus werethe best, with the diameters of bacteriostatic ring of 2. 72 mm, 3. 10 mm and 3. 05 mm respecitve-ly, and the minimal inhibitory concentration of 20 g/L,10 g/L,15 g/L,respectively. The research showed that introduction and cultivation of L. Japonica could improve its internal quality,and the ethyl acetate and butanolextraction extraction parts had strong antibacterial activity.关键词
