From the culture filtrates of Aspergillus sydowi two new metabolites, designated as sydonic acid and hydroxysydonic acid, have been isolated. Sydonic acid, C15H22O4, forms colorless needles, mp… Expand
Abstract. Ten strains isolated from industrial soy sauce producing koji mold were identified as Aspergillus sojae and distinguished from Aspergillus parasiticus morphologically and physiologically.… Expand
ABSTRACT The pathway from averufin (AVR) to versiconal hemiacetal acetate (VHA) in aflatoxin biosynthesis was investigated by using cell-free enzyme systems prepared from Aspergillus parasiticus.… Expand
Isolation and structural elucidation of rosellichalasin produced by Rosellinia necatrix, with mass spectral analysis and NMR spectroscopy
Abstract Structure of sorokinianin, a novel phytotoxin from an isolate of Bipolaris sorokiniana was determined to be… Expand
Screening tests of fungal metabolites were performed for developing new types of antioxidants and synergists for tocopherol (Toc). Flavoglaucin has been found to be an excellent antioxidant and… Expand
Desaturase activity that converts versicolorin B (VB) to versicolorin A (VA) was detected in the presence of NADPH in the microsomal fraction of Aspergillus parasiticus NIAH-26, which endogenously… Expand
Abstract Four metabolites were isolated and characterized from the phytopathogenic fungus Bipolaris coicis H-13-3. Radicinin and its diastereomer were phytotoxic against Job's tears ( Coix… Expand
Abstract Aszonalenin ( 1 ) has been isolated from Aspergillus zonatus together with LL-S490β ( 2 ) and the structure of 1 has been established by spectroscopic evidences and chemical transformation.
The biosynthetic pathways to spiciferone A and spicifernin were investigated by means of incorporation experiments with [1- 13 C], [2- 13 C], [1,2- 13 C], and [1- 13 C, 3 H 3 ]acetate and [S- 13 CH 3… Expand
