Ergone,a fungal metabolite derived from ergosterol,was previously isolated and identified from Polyporus umbellatus. Ergone is a major component of P. umbellatus known to have anti-aldosteronic diuretic effect and also displays cytotoxic activities. Most of mushroom's fruit bodies used for test contained less than 10 µg/g of ergone. But P. umbellatus have larger amount of ergone than any other ...

This study is a systematic overview of data on use of wild and semi-wild edible plants in nutrition of people in 1430 days of the siege of Sarajevo during aggression on Bosnia and Herzegovina (1992-1995). The author of this study spent all that time in Sarajevo. In 1993, the author prepared a survival program for people that included usage of edible wild plants. In addition, he conducted a deta...

By using only reverse-phase h.p.l.c., three fragments of prosomatostatin were isolated from an extract of a human pancreatic neuroendocrine tumour that produced somatostatin, vasoactive intestinal polypeptide and gastrin-releasing peptide. The amino acid composition of the peptides indicated that they represented prosomatostatin-(1-63)-peptide, prosomatostain-(65-76)-peptide and prosomatostatin...

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 compoun...

A TLC method with densitometric detection for identification and quantitation of indole compounds in methanolic extracts of fruiting bodies of Armillaria mellea (Vahl.) P. Kumm. (Basidiomycota)--Honey mushroom has been developed. The TLC method with densitometric detection was validated for determination of tryptamine and serotonin contents. The use of this chromatographic-densitometric method ...

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) ...
