Abstract

Abstract:

Objective: To explore the chemical constituents of the fungus Leccinum extremiorientale Singer. Methods:
Sephadex LH-20 and silica gel colunm chromatography were used for the isolation and purification. The structures of
compounds were identified by spectral analyses and physico-chemical properties. Results: Eleven compounds were isolated
and identified as methyl 2-pyrrolidinone-5-(L)-carboxylate (A), 2-pyrrolidinone-5-(L)-carboxylic acid (B), adenosine (C),
uridine (D), methyl α-D-ribofuranoside (E), (2R,3R)-2,3,4-threehydroxyl butyrate (F), tetrahydro-2,2,5,5-tetramethylfuran
(G), D-arabinono-1,4-lactone (H), 2-acetamido-1,6-anhydro-2-deoxy-D-glucopyranose (I), 2-acetamido-1,6-anhydro-2-
deoxy-D-galactopyranose (J) and ergosta-7,22-dien-3β,5α,6β-triol (K), respectively. Conclusion: Compounds A, B and E
through J are isolated from the fungus Leccinum extremiorientale for the first time.

Key words: Leccinum extremiorientale Singer, isolation and purification, chemical constituents
