Conversion of two diastereoisomeric 4a,10a-dihydrofusarubins, produced by Fusariumsolani, to fusarubin, norjavanicin, and a new compound, isofusarubin ((E)-6,7-dihydro-5,8-dihydroxy-2-methoxy-6-methylene-7-(2-oxopropylidene)-1,4-naphthalenedione), ha

Gamma-rays at mega rad quantities inhibited de novo synthesis and secretion of some enzymes in barley seeds during germination. The degree of inhibition, when the daily increase of enzyme activities was calculated, increased with the length of the ge

The previously unknown secalonic acid G has been isolated from Pyrenochaeta terrestris , and its structure determined by circular dichroism and 13 C nmr techniques including deuterium isotope 13 C chemical shift measurements to identify the linkage b

Gamma irradiation enhanced the leaching of reducing sugars from barley seeds into the water in which the seeds were shaken. Treatments prior to shaking in water, such as overnight soaking in water at 5°C and subsequent germination in Petri dishes fo

Cynodontin, emodin, endocrocin and secalonic acids A, E and G have been isolated from five strains of Pyrenochaeta terrestis. Aspergillus aculeatus produces emodin, endocrocin and secalonic acids B, D and F. No cynodontin was detected. Isolation of e

Analyses of the regiochemistry of [13C]acetate incorporation into fulvic acid ( 2 ) by Penicillium brefeldianum indicates that the metabolite is biosynthesized via a heptaketide intermediate assembled as a single chain of seven C2, units rather than

Six strains of Fusarium martii produced fusarubin and dihydrofusarubins A and B. Further examination of strains, T-77 and T-127, showed that four additional metabolites were produced. By 1H and 13C NMR spectral analyses, these additional metabolites
