Finding and evaluating information on natural products used as drugs can present challenges to the information professional. In this study, eight databases including resources retrieved on the Web were compared for relevancy and uniqueness. Ten reference questions related to natural products used as drugs were searched in the latest three year file of a number of databases, including MEDLINE, International Pharmaceutical Abstracts, and EMBASE/Excerpta Medica. In addition, the Web was searched for relevant Internet sites using the Alta Vista search engine. EMBASE/Excerpta Medica retrieved the largest number of relevant citations for four of the ten questions. MEDLINE, the Health Reference Center, and Alta Vista each retrieved the largest numbers in two questions. Overall, the standard medical databases were the first choice for the health professional and for many lay people because of their more extensive indexing and coverage of authoritative journals.
查找和评估用作药物的天然产物的信息，对信息专业人员来说可能是一项挑战。在本研究中，对包括从网络检索到的资源在内的八个数据库进行了相关性和独特性比较。在多个数据库（包括MEDLINE、《国际药学文摘》和EMBASE/医学文摘）的最近三年文档中，搜索了十个与用作药物的天然产物相关的参考问题。此外，使用Alta Vista搜索引擎在网络上搜索了相关网站。对于十个问题中的四个，EMBASE/医学文摘检索到的相关引文数量最多。MEDLINE、健康参考中心和Alta Vista在两个问题上各自检索到的数量最多。总体而言，标准医学数据库因其对权威期刊更广泛的索引和覆盖范围，成为健康专业人员和许多普通民众的首选。
