摘要
该文对荷叶离褶伞Lyophyllum decastes栽培子实体进行了化学成分的研究。采用硅胶、Sephadex LH-20柱色谱等多种方法分离纯化共得到13个化合物,并运用Ms和NMR等方法分析鉴定化合物的结构分别为腺嘌呤核苷(1)、N-(2-羟基二十一碳酰基)-1,3,4.三羟基-2-氨基-△^8,9。(E)-十八碳烯(2)、N.(2-羟基二十四碳酰基)-1,3,4-三羟基-2-氨基△^8,9(E)-十八碳烯(3)、烟酸(4)、1-O-β-D-吡喃葡萄糖基-(4E,8E)-2-N-(2-羟基棕榈酰)-9-甲基4,8-sphingadienine(5)、甘露醇(6)、麦角甾醇葡萄糖苷(7)、晚香玉苷(8)、N-(2-羟基二十二碳酰基)-1,3,4-三羟基-2-氨基-△^8,9(E)-十八碳烯(9)、N-(2-羟基二十三碳酰基).1,3,4-三羟基-2.氨基-△^8,9(E)-十八碳烯(10)、麦角甾-7,22-二烯-3β,5α,6β-三醇(11)、麦角甾醇(12)和麦角甾醇过氧化物(13)。所有化合物均为首次从荷叶离褶伞中分离得到,其中化合物2-10为首次从离褶伞属真菌中分离得到。
The chemical constituents from the fruiting bodies of Lyophyllum decastes ( Fr. ) Singer were studied in this paper. Thirteen compounds were isolated and purified by column chromatographies on silica gel and Sephadex LH-20. Their structures were identified by MS and NMR data analysis as adenosine (1), 2R, 3S, 4S, 8E)-2-[ (2'R)-2-hydroxyheneicosanoylamino ]-8-octadecene- 1, 3, 4-triol(2), ( 2R, 3 S, 4S, 8E) -2- [ ( 2'R ) -2-hydroxypentacosanoylamino ] -8-octadecene-1, 3, 4-triol ( 3 ), nicotinic acid ( 4 ), (4E, 8E)-2-N-2-hydroxytetracosanoy1-1-O-β-D-glycopyranosyl-9-methyl-4,8-sphingadienine(5), D-mannitol(6), ergosteryl-3-O-β- D-glucopyranoside (7), tuberoside (8), (2R, 3S, 4S, 8E) -2- [ (2'R) -2-hydroxybehenoylamino ] -8-oetadecene-1,3, 4-triol (9), (2R, 3S, 4S, 8E)-2-[ (2'R)-2-hydroxytricosanoylamino ]-8-octadecene-1,3, 4-triol(10), (22E, 24R)-ergosta-7, 22-dien-3β, 5a, 6β-tri- ol ( 11 ), ( 22E, 24R) -ergosta-5, 7, 22 -trien-3β-ol ( 12 ), and 5 a, 8 a-epidiory- ( 22E, 24R) -ergosta-6, 22 -dien-3β-ol ( 13 ), respectively. All the above compounds are first obtained from the mushroom and compounds 2-10 are reported to be obtained from the Lyophyllum for the first time.
