RT Journal Article ID 7e2f06e05cce4a2d A1 He, Xian-guo A1 Seleen, John T1 Chemical Analysis as a Quality Control Method for Medicinal Mushroom and Fungi Extracts JF International Journal of Medicinal Mushrooms JO IJM YR 2004 FD 2004-10-27 VO 6 IS 3 OP 10 AB There has been a much greater awareness of the value of medicinal mushroom extracts as dietary supplements in the last few years in the US. There is also more concern about the quality and potency of these mushroom extracts. As with standardized herbal medicine, chemical analytical methods play an important role to ensure accurate labeling by validating identity, purity, strength, and composition of mushroom extracts. The analytical methods used to evaluate polysaccharide content and other bioactive and nutritional compounds in mushroom extracts were developed in our laboratory using high-performance liquid chromatography (HPLC) and proton-nuclear magnetic resonance (proton NMR) techniques. The analytical methods for three of the most commonly used medicinal mushrooms—Coriolus (=Trametes) versicolor (yun zhi, turkey tail); Ganoderma lucidum (ling zhi, reishi); and Cordyceps sinensis (cordyceps, caterpillar fungus)—are discussed as examples in this article.
