title: [Determination of sugar components in wild and cultured sclerotia of Grifola umbellata (pers. ex Fr.) Pilat at different ages].
abstract: Our determination indicates that in both wild and cultured sclerotia of Grifola umbellata the contents of reducing sugar decrease with the growing years; the contents of Polysaccharide peak in the second year of growth; the contents of protein increase with the growing years; the contents of fat reaches maximum in the first year of growth; in cultured sclerotia ergosterol becomes highest in contents when the plant is two years old, while in wild sclerotia it remains lowest.
