摘要:

研究长柄炭角菌Xylaria longipes大米发酵物化学成分及其生物活性。应用硅胶柱色谱、Sephadex LH-20柱色谱、半制备型高效液相色谱等多种分离手段对长柄炭角菌大米发酵物乙酸乙酯部位进行化学成分研究,得到3个化合物,根据MS和NMR等波谱学方法确定其结构,分别为1-(3-ethyl-1,2,6-trihydroxycyclohexyl)-3-hydroxy-2-(methoxymethyl)propan-1-one(1)、(2E,4E)-6,8-dimethyldeca-2,4-dienoic acid(2)和(2E,4E)-8-methyldeca-2,4-dienoic acid(3)。化合物1为新的化合物,化合物23作为天然产物首次报道。三种抗细胞(角质细胞HaCaT、刀豆蛋白诱导的T淋巴细胞和脂多糖诱导的B淋巴细胞)增殖活性筛选结果显示,这些化合物均未表现出明显的生物作用。

Abstract:

This study aims to investigate the chemical constituents from the rice fermentation of Xylaria longipes and their biological activities.Three polyketones were isolated from the ethyl acetate layer of the rice fermentation of X. longipes by silica gels,Sephadex LH-20 column chromatography,and HPLC methods.Their structures were established based on NMR,MS and other spectroscopic techniques.1-(3-Ethyl-1,2,6-trihydroxycyclohexyl)-3-hydroxy-2-(methoxymethyl)propan-1-one (1) is a new compound. (2E,4E)-6,8-Dimethyldeca-2,4-dienoic acid (2) and (2E,4E)-8-methyldeca-2,4-dienoic acid (3) were reported as natural products for the first time.Their antiproliferative activities of compounds against three cell (keratinocyte HaCaT cell line,concanavalin A-induced T cells,and lipopolysaccharide-induced B cells) were evaluated,but none showed significant activities.

Key words: Xylaria longipes, rice fermentation, chemical constituents, polyketone
