INTRODUCTION: Today, with the development of better technologies and greater realization of their nutrient values, mushrooms have occupied an important place in food in several parts of the world 1. Researches on the nutritive value of edible mushrooms indicate that they may be regarded as healthy foods, even though they are deficient in calories and fat and consist of about 90% water 2, 3, 4.
Mushrooms have been reported to be of therapeutic value, useful in preventing diseases such as hypertension, hypercholesterolemia, cancer and also having antibacterial and antiviral properties. These functional characteristics are mainly due to their chemical composition 5, 6, 7, 8. The fruiting body of the mushroom is also a potential source of lignin and phenol degrading enzymes 9. While from clinical viewpoint, Bobeck and Galbavy (1999) showed that P. ostreatus elicited hypocholesterolemic and antherogenesis inhibition functions in rabbits and rat coutesy of its mycelial secretory products.
However, unlike the fruiting bodies of few other edible mushrooms such as L. edodes, G. fondosa and G. lucidium known for exhibiting antibacterial and antifungal activity in vitro, there is lack of information on the microbicidal properties of P. ostreatus coupled with inadequate data on its phytochemistry. It is hypothesized that knowledge of the phytoconstituents of P. ostreatus would provide an insight into its biological functions beyond nutrition when consumed.
Cultivation and production of edible mushrooms are on the increase, particularly in Europe, America and Asia. Their increased nutritional importance is due to the nutritive value of high-grade mushrooms, which almost equals that of milk 10. Mushrooms have been evaluated for their nutritional status on the basis of their chemical composition. Cultivated and wild mushrooms contain reasonable amounts of proteins, carbohydrates, minerals, fibres and vitamins 11, 12. Furthermore, mushrooms are low in calories, sodium, fats and cholesterol 13.
Edible mushrooms have long been considered to have medicinal value and to be devoid of undesirable effects 14. Most people eat mushrooms, mostly because of its flavor, meaty taste and medicinal value 15. Mushrooms generally possess most of the attributes of nutritious food as they contain many essential nutrients in good quantity 14. These substrates could be used in commercial production of mushrooms for food 15.
Mushrooms are considered as source of proteins, Vitamins, fats, carbohydrates, amino acids, and minerals Kalac, et.al (1991), the energy value varies according to species, which is about equal to that of an apple. Many studies gave proof of the fact that some mushrooms species (Pleurotus species for example) are useful in some Combinations to cure headache, stomach disorders, colds, fever, asthma and high blood Pressure Kalac, et al. (1991), other species are recommended to diabetic and anemic persons, owing to their Low carbohydrate and high folic acid content. Some mushrooms are reputed to possess antiallergic, anti-cholesterol, anti-tumor and anti-cancer properties ITA et al., (2006) & Sesli and Tuzen (1999)
Vitamins are essential nutrients found in foods. The requirements are small but they perform specific and vital functions essential for maintaining health. Fat-soluble vitamins -- vitamins A, D, E and K -- dissolve in fat before they are absorbed in the blood stream to carry out their functions. Excesses of these vitamins are stored in the liver. Because they are stored, they are not needed every day in the diet Alexander (1995).
Water-soluble vitamins dissolve in water and are not stored; they are eliminated in urine. We need a continuous supply of them in our diets. The water-soluble vitamins are the B-complex group and vitamin C. Gershoff (1993).
