摘要
对云南产的16种秋海棠属(BegoniaL.)植物进行了挥发物抗微生物活性实验,其中14种秋海棠为首次报道。结果表明,在所研究的16种秋海棠中,有8种秋海棠具有抗葡萄球菌(Staphyllococcusepidermidis)活性。而抗大肠杆菌(Escherichiacoli)活性最强的是厚壁秋海棠(BegoniasilletensisC.B.Clarke),假厚叶秋海棠(B.pseudodryadisC.Y.Wu)和秋海棠(B.grandisDryand.)。只有铁甲秋海棠(B.masonianaIrmsch.)和毛叶秋海棠(B.rexPutz.)对白假丝酵母菌(Candidaalbicans)有抗性。作为室内盆栽花卉被广泛应用的秋海棠,不仅可以美化室内环境,而且还可以作为药用和净化室内环境的生态产品进行推广应用。
Begonias are widely used as ornamentals for their attractive flowers and foliages. The substances of phytoncids have bactericidal, fungicidal and protistocidal activities as discovered by previous researches. Phytoncid activity of volatile emissions of species of the genus Begonia L. collected from various natural habitats in Yunnan Province, China, was studied. Sixteen species of Begonia were studied with 14 species being studied for the frrst time. The results indicated that eight species exhibited activity towards Staphyllococcus epidermidis. The most active towards Escherichia coli was Begonia silletensis, B. psuedodryadis and B. grandis. Only B. masoniaria and B. rex were active towards Candida albicans. The species of the genus Begonia studied which exhibited antimicrobic activity may be recommended for the use of medicinal and ecological phytodesign.
