Structure and bioactivity of a polysaccharide containing uronic acid from Polyporus umbellatus sclerotia.
Polyporus umbellatus is a medicinal fungus, has been used in traditional Chinese medicine for thousands years for treatment of edema, scanty urine, vaginal discharge, jaundice and diarrhea. The structure of a soluble polysaccharide (named PUP80S1), purified from the sclerotia of Polyporus umbellatus was elucidated by gas chromatography (GC), GC-mass spectrometry and nuclear magnetic resonance s...
متن کاملIsolation of high quality RNA from Polyporus umbellatus
Background: The dried sclerotium of medicinal fungus Polyporus umbellatus (Pers.) Fries has many pharmacological functions such as diuretic and anticancer activity, in which high-content polysaccharides may play an important role. However, RNA isolation is difficult in filamentous fungi and lacking in P. umbellatus. Results: Five methods for RNA extraction from five strains collected from four ...
متن کاملImprovement of Ergone Production from Mycelial Culture of Polyporus umbellatus
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 ...
متن کاملOxalic acid and sclerotial differentiation of Polyporus umbellatus
The present investigation aimed to uncover the effects of exogenous oxalic acid during the sclerotial formation of Polyporus umbellatus, with an emphasis on determining the content of the endogenic oxalic acid in the fungus. To this end, the oxalic acid content of the vegetative mycelia, sclerotia, culture mediums and sclerotial exudate were measured using High Performance Liquid Chromatography...
متن کاملSWATH label-free proteomics analyses revealed the roles of oxidative stress and antioxidant defensing system in sclerotia formation of Polyporus umbellatus
Understanding the initiation and maturing mechanisms is important for rational manipulating sclerotia differentiation and growth from hypha of Polyporus umbellatus. Proteomes in P. umbellatus sclerotia and hyphae at initial, developmental and mature phases were studied. 1391 proteins were identified by nano-liquid chromatograph-mass spectrometry (LC-MS) in Data Dependant Acquisition mode, and 1...
