Biologically Active Substances from Mushrooms in Yunnan, China

As a part of our search for naturally occurring bioactive metablites of mushrooms, we investigated the chemical constituents of eight Basidiomycetes and Ascomycetes fungi (Albatrellus confluens, Russula lepida, Thelephora ganbajun, Russula cyanoxantha, Polyporus ellisii, Tuber indicum, Engleromyces gotzii, Tremella aurantilba, Laetiporus sulphureus and Tylopilus plumbeoviolaceus), and isolated a number of novel terpenoids, phenolics and nitrogen-containing compounds.The isolation, structural elucidation and biologically activity of the new compounds are discussed.1．Introduction Yunnan Province, southwest of China, is one of the areas with the richest and diverse bioresources in the world based on its unique geoenviroment, diverse geomorphology and three-dimensioal differentiation of climate.About 1500 species of mushrooms are now known in Yunnan.Edible and inedible
