摘要

Our ongoing research into the chemical diversity of terrestrial actinomycetes associated with the plant rhizosphere has led to the discovery of rare metabolites, such as leopolic acid A and juniperolide A, which were isolated from Streptomyces sp. cultured from the rhizosphere of the plant Juniperus excelsa. The discovery of such rare and chemically diverse structures further prompted us to investigate this new source of biodiversity in order to expand and enhance our chances of discovering novel secondary metabolites. During our recent investigation into the secondary metabolism of rare terrestrial actinomycetes, we recovered a Streptomyces sp. (Lv-4-15) from the root zone of the plant Phyllostachys viridi-glaucescens. HPLC-DAD-MS analysis of a small-scale liquid cultivation (100 ml) revealed biosynthetically related compounds (mlz 260 (1) and 232 (2)) sharing a common UV spectrum (L_(max)= 210 and 254nm).
