Investigation of Naturally Occurring Drug Materials in Indonesia-3

印度尼西亚是一个世界著名的国家，自然资源丰富，这可以保证我们有许多迄今为止未知的药用植物。然而，这些药用植物中的生物活性成分的化学和生物学研究尚未完全展开，我们的研究项目题为“印度尼西亚天然药用物质的研究-3”，旨在揭示天然存在的药用物质，即：e. 1990年，我们在印度尼西亚苏门答腊岛的本库鲁省、廖内省和北苏门答腊省进行了调查，从当地居民那里收集了360种传统药用植物的资料，并收集了68种药用植物进行化学研究，1991年，所有标本在印度尼西亚博戈尔的茂物植物标本馆进行了植物学鉴定。这些标本的乙醇提取物，并通过几种色谱技术和生物测定在大坂大学进行了检查。分析研究正在进行中。我们已经获得了一些有希望的证据，因此，对我们调查中收集的材料进行化学和生物学研究可能会导致我们发现新的生物活性物质。与印度尼西亚生物研究与发展中心（印度尼西亚参与组织）的合作进展非常顺利。今后将继续以这种方式进行这种令人满意的合作。

Indonesia is a world-prominent country rich in natural resources an this may guarantee us for many medicinal plants hitherto unknown to be available. However, chemical and biological investigations of bioactive principles in those medicinal plants, have not yet been fully carried out.Our research project entitled "Investigation of Naturally Occurring Drug Materials in Indonesia-3" aims at revealing the naturally occurring drug materials, i. e. medicinal plants, in Indonesia and points towards the development of the academic exchange between Japan and Indonesia.In 1990, we surveyed in Province Bengkulu, Riau, and North Sumatera in Sumatera Island, Indonesia and collected information about 360 kinds of traditionally used medicinal plants from local people and gathered 68 kinds of medicinal plants for chemical study, which will be carried out at Osaka University.In 1991, all specimens were botanically identified at Herbarium Bogoriense, Bogor, Indonesia. The alcoholic extract of these specimens were made and examined by means of several kinds of chromatographic technique and bioassay at Osaka University. The analytical studies are in progress. We have so far obtained some promising evidence so that the chemical and biological studies of those materials collected in our survey may lead us to find new biologically active substances.The collaboration with Research and Development Center for Biology-LIPI, Indonesia, which is the Indonesian participating organization, has been proceeded very smoothly. The desirable collaboration will certainly be continued in this manner hereafter.
