The extraction of triterpenoids and phenolic compounds from Ganoderma lucidum was optimized by using the response surface methodology (RSM), using heat and ultrasound assisted extraction techniques (HAE and UAE). The obtained results were compared with that of the standard Soxhlet procedure. RSM was applied using a circumscribed central composite design with three variables (time, ethanol content, and temperature or ultrasonic power) and five levels. The conditions that maximize the responses (extraction yield, triterpenoids and total phenolics) were: 78...

Excessive glucose concentrations in blood and cells promote the intensification of auto-oxidation. This is one of the mechanisms through which free radicals form in hyperglycemia. As a result of hyperglycemia, oxidative stress develops and lipid peroxidation (LPO) is enhanced. Erythrocytes are particularly susceptible to reactive oxygen species and LPO, which can violate cell functions. This article describes the analysis of the influence of mycelia from the medicinal mushrooms Agaricus brasiliensis and Ganoderma lucidum on the enzymatic link of the antioxidant system in rat erythrocytes under streptozotocin-induced diabetes mellitus...

Cancer is a multifactorial disease, causing behavioral and metabolic alterations, leading to uncontrolled cell proliferation with collateral weakening of immune system. Crucial balance between cell proliferation and cell death determines the fate of a cell, which might progress towards survival or apoptosis. Apoptosis is a complex, programmed, and highly regulated process causing dramatic morphological and biochemical perturbations in the cellular machinery. Ganoderma lucidum is a basidiomycetes, polypore mushroom known for its pharmacological properties in cancer...
