Three new lanostanoid triterpenes--ganotropic acid (1), 3β,7β,15α,24-tetra- hydroxy-11,23-dioxo-lanost-8-en-26-oic acid (2) and 3β,7β,15α,28-tetrahydroxy-11,23- dioxo-lanost-8,16-dien-26-oic acid (3)--were isolated from the n-BuOH extract of the fruiting bodies of the mushroom Ganoderma tropicum. Their structures were elucidated by 1D and 2D NMR spectroscopy, as well as HR-EI-MS data.

BACKGROUND Two species of Ganoderma, G. sinense and G. lucidum, are used as Lingzhi in China. Howerver, the content of triterpenoids and polysaccharides, main actives compounds, are significant different, though the extracts of both G. lucidum and G. sinense have antitumoral proliferation effect. It is suspected that other compounds contribute to their antitumoral activity. Sterols and fatty ac...

Species in the genus Ganoderma include several ecologically important and pathogenic fungal species whose medicinal and economic value is substantial. Due to the highly similar morphological features within the Ganoderma, identification of species has relied heavily on DNA sequencing using BLAST searches, which are only reliable if the GenBank submissions are accurately labeled. In this study, ...

OBJECTIVE To investigate the effects of Ganoderma spores on mitochondria-related molecular substances in hippocampus of young rats birthed by rats with gestational hypertension. METHODS Nitric oxide synthase (NOS) inhibitor Nw-nitro-L-arginine methylester (L-NAME) was intraperitoneally injected into pregnant rats to induce gestational hypertension, and Ganoderma spores were administered orall...

Jacaranda mimosifolia trees have been progressively dying due to Ganoderma root and butt rot disease in Pretoria (the "City of Jacarandas") for many years. Ganoderma austroafricanum was described from these trees previously but this was based on a single collection. This study treats a substantially expanded collection of isolates of Ganoderma made from all dying trees where basidiomes were pre...

This study aimed to evaluate the efficacy and safety of Ganoderma lucidum for the treatment of hyperglycaemia and other cardiovascular risk components of metabolic syndrome using a prospective, double-blind, randomised, placebo-controlled trial. Eighty-four participants with type 2 diabetes mellitus and metabolic syndrome were randomised to one of three intervention groups: Ganoderma lucidum, G...

Ganoderma includes species of great economic and ecological importance, but taxonomists judge the current nomenclatural situation as chaotic and poorly studied in the neotropics. From this perspective, phylogenetic analyses inferred from ribosomal DNA sequences have aided the clarification of the genus status. In this study, 14 specimens of Ganoderma and two of Tomophagus collected in Brazil we...

According to recent studies, Ganoderma may be the third genus, after Alternaria and Cladosporium, the spores of which cause symptoms of allergy, and concentration is related to meteorological factors. The aerobiology of Ganoderma spores in Szczecin in urban and suburban districts was examined using Lanzoni Volumetric Spore Traps in 2008-2010. Ganoderma spores were present in the atmosphere on m...

White-rot fungi (WRF) and their ligninolytic enzymes (laccases and peroxidases) are considered promising biotechnological tools to remove lignin related Persistent Organic Pollutants from industrial wastewaters and contaminated ecosystems. A high diversity of the genus Ganoderma has been reported in Cuba; in spite of this, the diversity of ligninolytic enzymes and their genes remained unexplore...

objective: ganoderma lucidum (g. lucidum) has been suggested to increase serum insulin level.this study was undertaken to investigateits direct effect on the islets of langerhans. material and methods: male albino wistar rats were anesthetized and the islets were isolated after digestion of the pancreas with collagenase. the islets were incubated for 60 min in krebs bicarbonate buffer containin...
