Herbal medicines have been in use for many years and remain widespread in developing countries; whereas, the use of complementary alternative medicine is on the increase in developed countries. is important for its medicinal benefits among most communities in treating a wide range of ailments.
Plants were collected from a cluster in Siaya, Nandi and Nakuru counties (Kenya). Stem bark, root bark, leaves, flowers and immature pods were obtained; air-dried and ground into fine powder. Methanol was used to extract the plant extracts. The extracts were reconstituted in water and incorporated into growth media to obtain 0%, 2.5%, 5%, 7.5% and 10%. Bioassays were carried out on (ATCC 28942) and (14053). The growth of cultures on the plates was measured over a period of sixteen days. The area under disease progress stairs was determined and subjected to ANOVA and comparison of means using LSD.
Results indicated that the growth of was not significantly affected by the plant extracts. Growth of was completely inhibited by immature pods extract at 10%, the leaves and flowers extracts inhibited the growth at 7.5%. The stem and root bark extracts inhibited growth at low dosages of 2.5- 5 %.
There is need to carry out research on root and stem barks to identify the active phytochemicals that contribute to their high efficacies. On species conservation, harvesting of roots may lead to depletion of .
草药已使用多年,在发展中国家仍广泛应用;而在发达国家,补充替代医学的使用正在增加。它在大多数社区治疗多种疾病方面具有药用价值,这一点很重要。
从肯尼亚的西亚亚、南迪和纳库鲁县的一个集群中采集植物。获取茎皮、根皮、叶子、花朵和未成熟的豆荚;风干并磨成细粉。用甲醇提取植物提取物。将提取物在水中复溶并加入生长培养基中,得到0%、2.5%、5%、7.5%和10%的浓度。对金黄色葡萄球菌(ATCC 28942)和大肠杆菌(14053)进行生物测定。在十六天的时间内测量平板上培养物的生长情况。确定疾病进展阶梯下的面积,并进行方差分析和使用最小显著差法的均值比较。
结果表明,植物提取物对金黄色葡萄球菌的生长没有显著影响。10%的未成熟豆荚提取物完全抑制了大肠杆菌的生长,7.5%的叶子和花朵提取物抑制了其生长。茎皮和根皮提取物在2.5%-5%的低剂量下抑制生长。
有必要对根皮和茎皮进行研究,以确定有助于其高效的活性植物化学物质。在物种保护方面,采集根部可能会导致该物种的枯竭。
