ISOLATION AND CHARACTERIZATION OF SIX HIGHLY INTRINSIC FLUORESCENT METABOLITES IN ARMILLARIA MELLEA (VAHL. EX. FR.) KARST
نویسندگان: ثبت نشده
چکیده مقاله:
Six fluorescent compounds were isolated and characterized in rhizomorph of A. mellea and were presented first as: F , F , F , MF , MF and MF . These compounds differed by Rf on chromatoplaque, max in UV spectra and ex, em and max in fluorescence spectra. Their GC-MS analysis indicated that F has a phenolic moiety and the other five are the benzenic derivatives. F compound was more fluorescent resulting from its hydroxyl group. The difference between the fluorescent compounds of rhizomorph and hyphae suggests the participation of some of these compounds in differentiation. Moreover, these compounds may have antibiotic activity against their hosts or enemies

متن کاملPOLYPHENOL OXIDASE ACTIVITY AND DIFFERENTIATION OF RHIZOMORPH IN ARMILLARIA MELLEA (VAML. EX. FR.) KARST
Polyphenol oxidase (PPO) activity varied in differentiation from hyphae to rhizomorph and croute in A. mellea. In undifferentiated hyphae there was not any PPO activity, while croute showed the highest activity. Electrophoresis in the presence of SDS allows the detection of intensive enzyme forms of PPO, and can also convert slower migrating enzyme forms to faster ones. Some fluorescent co...

The organic solvent extraction of Armillaria mellea showed different highly intrinsic fluorescent compounds either in rhizomorph or in hyphae (F , F , F , MF , MF and MF ). The characterization of ultraviolet and fluoro-spectrophotometry of these compounds has been exhibited. Thin layer chromatography and fluorescent spectrum of hyphae and rhizomorph indicated an additional compound (FH) ...
