title: Herbicidal nucleosides from microbial sources.
abstract: The structures of five naturally-occurring herbicidal nucleosides have been determined by spectral analysis. Three (5'-deoxyguanosine, coaristeromycin and 5'-deoxytoyocamycin) are novel natural products while the remaining two (coformycin and adenine 9-beta-D-arabinofuranoside) are known natural products which have not previously been reported to be herbicidal.
