In search of new biologically active compounds in nature, we have been investigating naturally occurring substances on the following subjects : I. chemical studies on naturally occurring drug materials [a) elucidation of bioactive constituents in natural drugs, b) elucidation of scientific basis for crude drug processing, and c) investigation of bioactive constituents in food materials], II. exploitation of new pharmaceuticals in nature [a) investigation of marine natural products and b) exploitation of Indonesian medicinal plants], and III. synthetic studies on bioactive natural products [a) chemical modification of naturally abundant carbohydrates and terpenoids and b) synthetic studies of complex lipids]. This article reviews the results obtained in our laboratory since 1978 on the subjects of I-a, b, c, II-a, and III-a.
