目的 研究繁茂膜海绵Hymeniacidon perleve来源青霉属真菌Penicillium sp.HPQJ10的次级代谢产物。方法 利用正相硅胶柱色谱、葡聚糖凝胶Sephadex LH-20以及半制备高效液相等色谱分离手段进行分离纯化,根据波谱学数据鉴定化合物结构。结果 从发酵产物中共分离到14个单体化合物,分别鉴定为N-[(Z)-2-(4-hydroxyphenyl) ethenyl]formamide(1)、2,4-dimethoxyphenyl acetate(2)、6,8,5',6'-四羟基-3'-甲基黄酮(3)、4-羟基苯乙酸(4)、cyclo-(L-Pro-L-Val)(5)、cyclo-(L-Pro-L-Leu)(6)、邻苯二甲酸二异丁酯(7)、邻苯二甲酸二丁酯(8)、7-hydroxy-2-(2-hydroxypropyl)-5-methyl chromone(9)、2-(2,4-dimethoxylphenyl)-3-(4-hydroxybenzyl)-1,2,4-triazole(10)、(22E,24R)-麦角甾-5,7,22-三烯-3β-醇(11)、cyclo-(Leu-Pro-Ile-Pro)(12)、2,4-二甲氧基苯甲酸(13)、3-甲氧基苯酚(14)。结论 除化合物1、3、10、11 以外,其他化合物均为首次从该菌种中分离得到。

Objective To study the secondary metabolites of sponge-derived fungus Penicillium sp. HPQJ10. Methods The compounds were isolated and purified by chromatographic methods on silica gel, Sephadex-LH20 columns and semi-prep HPLC. The structures were established on the basis of spectroscopic data interpretation. Results Forteen compounds were isolated and identified as N-[(Z)-2-(4-hydroxyphenyl) ethenyl] formamide (1), 2,4-dimethoxyphenyl acetate (2), 6,8,5'6'-tetrahydroxy-3'-methylflavone (3), 4-hydroxyphenylacetic acid (4), cyclo-(L-Pro-L-Val) (5), cyclo-(L-Pro-L-Leu) (6), diisobutyl phthalate (7), dibutyl phthalate (8), 7-hydroxy-2-(2-hydroxyPropyl)-5-methyl chromone (9), 2-(2,4-dimethoxylphenyl)-3-(4-hydroxybenzyl)-1,2,4-triazole (10), (22E,24R)-ergenol-5,7,22-trien-3β-ol (11), cyclo-(Leu-Pro-Ile-Pro) (12), 2,4-dimethoxybenzoic acid (13), and 3-methoxyphenol (14). Conclusion Except for compounds 1, 3, 10, and 11, other compounds are isolated from Penicillium sp. for the first time.
