    Chemical profiling of ganoderma lucidum of bathinda region
    (Central University of Punjab, 2013) Gill, Balraj Singh; Kumar, Sanjeev
    Ganoderma lucidum is a basidiomycete's fungus with numerous pharmacological properties. The important ingredients of Ganoderma lucidum are terpenoids and polysaccharides etc. which play momentous role in immunomodulating, anti-inflammatory, anti-cancer, anti-diabetic and anti-oxidative. Mechanism of anticancer is still unrevealed. Aim of the present study was to analyse phytochemical difference in the Ganoderma lucidum growing on different hosts in Malwa region. Biomolecules play an imperative role in growth and development. Stress condition remodels the physiology, morphology and development of plant. To combat with stress, plants evolve with time and synthesize secondary metabolites. Stress tolerance ability is generated by overexpression of isoenzyme, intracellular targeting of anti-oxidants and overexpression ability of anti-oxidative enzyme. Ganoderma lucidum was analysed for different parameters such as total sugars, reducing sugars, starch, proteins, phenols, antioxidant property and flavonoids by standard procedures which was collected in different stages of development on different hosts, such as Azadirachta, Acacia, Bauhinia, Melia, and Dalbergia spp. It manifests fungus-host relationship and amount of phytoconstituent synthesized. The biochemical estimation showed 38.1±0.0481 g/100g of total sugars, 19±5.925 g/100g of reducing sugars, 57.3±3.333 g/100g of starch, 42±4.2% of proteins, 9.7±0.066% of phenols, 86.31%±5.480 scavenging activity in term of % inhibition and 5.26 ±0.6 mg/g of flavonoids. Complete analysis shows that except flavonoids all phytochemicals content was exceptionally high. Terpenoids analysis showed variation within the different hosts. Ganoderic acid, which is most active anticancerous molecule showed variation within different hosts. It can be concluded from the preliminary studies that there are variations in the chemical constituents of GL with change in host which makes it a "chemovariant"
