As described in the preceding paper, bostrycin, an antibiotic produced by Boetryconema alpsxtre, was isolated recently with chloroform extraction from the cultured broth of this parasitical mould on PoZygonum fitiforme Thunb. var. neofitiforme Ohwi. This antibiotic is active mainly against some spec
The structure of AlVMoOr was solved by direct methods from high resolution X-ray powder diffraction data and refined by the Rietveld method. The lattice constants are a=5.3763(3)& b=8.1644(3)A and c=12.7312A. S pace group Pmcn followed from the systematic extinctions and was confirmed by the success
403 001 (India) Summary, An X-ray crystal structure analysis of alloisolongifololp-nitrobenzoate as 2 has necessitated a revision of the earlier assigned structure 2 to 2 for alloisolongifolene, the parent hydrocarbon. IN THE RECENT assignment' of the structure 2 to alloisolongifolene, the remarkab
