摘要:

目的:研究远东疣柄牛肝菌子实体的化学成分。方法:采用Sephadex LH-20凝胶色谱柱和硅胶色谱柱进行分离纯化,通过波谱数据和理化常数鉴定化合物的结构。结果:从远东疣柄牛肝菌中分离鉴定出11 种化合物:5-(L)-羰基-四氢吡咯-2-甲酸甲酯(A)、5-(L)-羰基-四氢吡咯-2-甲酸(B)、腺苷(C)、尿嘧啶核苷(D)、α-甲基-D-呋喃核糖(E)、(2R,3R)-2,3,4-三羟基丁酸(F)、2,2,5,5-四甲基四氢呋喃(G)、D-阿拉伯糖酸-1,4-内酯(H)、2-乙酰胺基-1,6-脱水-2-脱氧-D-吡喃型葡萄糖(I)、2-乙酰胺基-1,6-脱水-2-脱氧-D-吡喃型半乳糖(J)和麦角甾-7,22-二烯-3β,5α,6β-三醇(K)。结论:化合物A、B和E~J为首次从远东疣柄牛肝菌中分离得到的化合物。

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
