Lactarane type sesquiterpenoids as inhibitors of leukotriene biosynthesis and other, new metabolites from submerged cultures of Lentinellus cochleatus (Pers. ex Fr.) Karst.

ISOLATION AND CHARACTERIZATION OF SIX HIGHLY INTRINSIC FLUORESCENT METABOLITES IN ARMILLARIA MELLEA (VAHL. EX. FR.) KARST

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 f...

POLYPHENOL 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...

Comparison between antioxidant activity and bioactive compounds of Ganoderma applanatum (Pers.) Pat. and Ganoderma lucidum (Curt.) P. Karst from Iran

Members of Ganoderma genus, belong to Basidiomycota, such as Ganoderma applanatum and Ganoderma lucidum have been noticed in traditional and modern medicine and pharmacology for their medicinal properties and bioactive compounds. The present study is undertaken to determine whether there is difference between chemical properties of G. applanatum and G. lucidum. The fresh mature fruiting bodies ...
