Field Study on natural medicinal resources in Bangladesh

2008-2011年，该研究项目的代表Masami Ishibashi每年都会访问孟加拉国，对孟加拉国的天然药物资源进行实地调查研究，主要是热带植物。结果，收集到的植物种类近200种，主要是野外特有植物和当地种植的草药。对这些植物材料的提取物进行了针对Wnt、hedgehog和TRAIL等信号通路的筛选试验，并从活性样品中分离出了几种新的生物活性天然产物。

In 2008-2011 the representative of this research project (Masami Ishibashi) visited Bangladesh every year and investigated field-study on natural medicinal resources in Bangladesh mainly on tropical plants. As a result, approximately nearly 200 kinds of plant species were collected, and they were mainly field-characteristic plant species as well as locally cultivated medical herbs. Extracts of these plant materials were subjected to screening tests against signaling pathways such as Wnt, hedgehog, and TRAIL, and from active samples several new bioactive natural products were isolated.
