摘要: 采用硅胶、RP-18、Sephadex LH-20等多种材料对石榴嗜蓝孢孔菌发酵液的乙酸乙酯提取部分分离纯化,通过理化方法和波谱分析对化合物进行结构鉴定。分离鉴定了11个化合物,经波谱数据分析分别鉴定为角鲨烯(1)、棕榈酸(2)、(9Z,12Z)-十八烷二烯酸(3)、(22E,24R)-ergosta-7,22-dien-3β-ol(4)、亚油酸甲酯(5)、麦角甾-4,6,8 (14),22-四烯-3-酮(6)、麦角甾-5,7,22-三烯-3β-醇(7)、过氧麦角甾醇(8)、2α-methoxyl-3β,9β-dihydroxyergosta-7,22-diene(9)、3β,6β-dihydroxycinnamolide(10)、麦角甾-7,22-二烯-3β,5α,6β-三醇(11)。化合物10是一个新的drimane型倍半萜,其他化合物均首次从该种真菌中分离得到。

Abstract: The ethyl acetate extract of Fomitiporia punicata were separated and purified by silica gel,RP-18,Sephadex LH-20 column chromatography.Their structures were determined on the basis of physicochemical properties and spectroscopic analysis.Eleven compounds were isolated and identified as squalene (1),palmitic acid (2),linoleicacid (3),(22E,24R)-ergosta-7,22-dien-3β-ol (4),methyl linoleata (5),(22E,24R)-ergosta-4,6,8(14),22-tetraen-3-one (6),(22E,24R)-ergosta-5,7,22-trien-3β-ol (7),(22E,24R)-5α,8α-epidioryergosta-6,22-dien-3β-ol (8),2α-methoxyl-3β,9β-dihydroxyergosta-7,22-diene (9),3β,6β-dihydroxycinnamolide (10),(22E,24R)-ergosta-7,22-dien-3β,5α,6β-triol (11).Compound 10 was a new drimane-type sesquiterpenoid,named as 3β,6β-dihydroxycinnamolide,other compounds were isolated from Fomitiporia punicata for the first time.

Key words: Fomitiporia punicata, chemical constituent, sesquiterpenes, 3&beta, ,6&beta, -dihydroxycinnamolide
