Screening of selected ethno-medicinal plants of Manang District, Central Nepal for antibacterial activity.

摘要

A series of 31 medicinal plants used by the Manangi community of Manang District, Nepal, were screened for antibacterial activity. These plants are used to treat ailments including sore throat, cough and diarrhoea, thought to be caused by bacterial infections. Out of 31 species, 19 showed antibacterial activity against Salmonella typhi, 18 against Escherichia coli, 17 against Staphylococcus aureus, 17 against Streptococcus faecalis, and 12 showed antibacterial activity against Pseudomonas aeruginosa. The results of the laboratory work are encouraging because most of the selected plants contain antibacterial substances which lend support to the claims of Manangi medicinal healers regarding the biological usefulness of the tested plants. It is hoped that this study will both encourage the scientific community in Nepal to search for alternative, affordable and easily available antibiotics of plant origin, and as well as conservation of important plant and cultural resources in Nepal.
