Medicinal Properties of Pleurotus Species (Oyster Mushroom): A Review
Mushrooms have been used as food supplement from times immemorial not only for their flavour, aroma and nutritive values but also for their medicinal properties as evident from ancient literature. In the present day world they are known for culinary values due to their high-quality proteins, vitamins, fibres and many medicinal properties and accordingly they are called nutraceuticals. Pleurotus as health promoter and environmental restorer is gaining more importance as compared to other medicinal mushrooms resulting in an upsurge in their R and D activities during the past two decades. The chemical nature of the bioactive compounds present in this mushroom includes: polysaccharides, lipopolysaccharides, proteins, peptides, glycoproteins, nucleosides, triterpenoids, lectins, lipids and their derivatives. In this review databases were extensively searched, collected and analysed with an aim to update the present status and to project future prospects of Pleurotus for their biomedical potentials. The presented information will give a new notion to researchers for upgrading Pleurotus species from functional food to holistic mushroom medicine.
