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.

5,8 alpha-Epidioxy-(22E)-24-nor-5 alpha-cholesta-6,22-dien-3 beta-ol (8 approximately) has been isolated from the sea pen Virgularia sp. and has been observed as a component of a mixture isolated from the opisthobranch mollusk Adalaria sp. The structure of 8 approximately was deduced from spectroscopic data. A further six sterol peroxides isolated from Adalaria and six from Virgularia were tentatively identified on the basis of spectroscopic analysis of mixtures.
