Purification and Identification of Chemical Constituents of Basidiomycete Daedaleopsis tricolor Collected from Mazandaran Province, Iran
Background and purpose: Mushrooms are natural sources that have antitumoral effects, immunomodulatory and anti-oxidant effects. One of the fungus which remained intact is Daedaleopsis tricolor that belongs to the family of Polyporaceae. There are limited phytochemical investigations on other species of this genus, so, we aimed at performing a phytochemical analysis of this fungus. Materials a...
متن کاملIdentification of Ergosterol in Mushrooms
Mushroom has gained popularity as prized table delicacy with high nutritive and medicinal value. Ergosterol is a biological precursor (a provitamin) to vitamin D2. The contents of vitamin D2 and sterols in some wild and cultivated mushrooms were determined. Vitamin D2 was determined using an HPLC method, including saponification and semipreparative normalphase HPLC purification Lv et al. [1]. C...
متن کاملIsolation and Identification of Ergosterol and Mannitol from Aspergillus Fischeri*
Sterols are widely distributed in nature. It has been suggested that they be classified into three groups according to their occurrence : (1) zoosterols, the animal sterols (cholesterol, coprosterol) ; (2) phytosterols, the plant or vegetable sterols (sitosterol, stigmasterol) ; and (3) mycosterols, the sterols found in fungi (ergosterol, fungisterol). Although ergosterol has been detected in s...
متن کاملAbsorption Spectra Studies on Cholesterol and Ergosterol.*
In the previous paper it was shown that highly purified spinal cord cholesterol is still activatable to antirachitic activity when irradiated in the solid form by a Cooper Hewitt mercury vapor quartz lamp. Although the activatability is decreased by the purification methods employed, nevertheless these purified products can again be rendered at least 25 times more activatable if heated under th...
متن کاملNew Shewhart-type synthetic bar{X} control schemes for non-normal data
In this paper, Burr-type XII ̄X synthetic schemes are proposed as an alternative to the classical ̄X synthetic schemes when the assumption of normality fails to hold. First, the basic design of the Burr-type XII ̄X synthetic scheme is developed and its performance investigated using exact formulae. Secondly, the non-side-sensitive and side-sensitive Burr-type XII ̄X synthetic schemes are int...
