石榴在植物分类学上属石榴科石榴属植物,目前,我国已有100个以上的栽培品种,还有几个不结实的重瓣观赏品种和变种。作为栽培的只有一个种,即石榴(Punica granattum L.).石榴原产伊朗、阿富汗、中亚级亚一带,引入我国种植已有2000多年.石榴被视为"合家团圆"、"多子多福"的吉祥物,多作贡品和馈赠亲友的最佳礼品,需求量越来越大。 相似文献

目的:研究石榴花挥发油的化学成分及β-葡萄糖苷酶对其的增香作用。方法:使用挥发油提取器提取石榴花的挥发油,以GC-MS法进行分析鉴定,用面积归一化法获得各化合物的相对含量。结果:分别从无酶和有酶的石榴花挥发油提取物中确证了42个化合物。证明β-葡萄糖苷酶可以增加石榴花中某些香精成分的相对含量,但也使其中某些成分的相对含量减少。结论:石榴花中的化学成分十分丰富,GC-MS可以对石榴花挥发油进行良好的分离鉴定,同时证明β-葡萄糖苷酶对石榴花的增香作用不显著。 相似文献

Pomegranate (Punica granatum) is an important source of polyphenols with assessed antioxidant properties. The aims of this study were: (i) the characterization of the monomeric phenolic variability on each isolated fruit component (endocarp, mesocarp, aril); (ii) the study on the effect of pomegranate fruit components on human thrombin amidolytic activity. Collectively, our data show that pomegranate components contain bioactive metabolites (mainly ellagic acid) and suggest a potential role for the pomegranate extract in the regulation of a number of physio-pathological processes involving thrombin (or thrombin-like proteinase). 相似文献

石榴果实香气物质的研究 总被引:7,自引:0,他引:7
利用顶空固相微萃取法提取大青皮甜石榴整体果实、石榴皮和石榴籽汁的芳香物质,气相色谱-质谱联机定性定量分析,检测香气组分.石榴香气组分中以醛类和醇类为主,在石榴整体果实中占总峰面积的78.32%和14.52%,在石榴皮中占89.88%和4.70%,在石榴籽汁中占82.15%和9.78%.石榴中共检测出77种香气组分,其中石榴果实、果皮和籽汁中分别检测出42种、39种和43种.香气成分中共有的成分为18种,在果实、果皮和籽汁中分别占总峰面积的94.62%、95.59%和93.76%.2-己烯醛、己醛、3-己烯醛、(E,E)-2,4-己二烯醛为石榴的主要香气成分,在果实、果皮和籽汁分别占78.27%、89.78%和81.79%.结果表明,石榴香气组分以C6醛和醇为主,石榴不同部分香气组分差异也主要表现在C6醛和醇含量的差异上. 相似文献

Pomegranate (Punica granatum) is native to Iran and neighbouring countries and is negatively affected by a wide range of diseases. Canker and dieback diseases caused by Cytospora punicae and members of the family Botryosphaeriaceae are the main trunk diseases on pomegranate. In summer 2017, progressive dieback of branches on some young pomegranate trees was observed in orchards of the Gorgan Region (Golestan province, Northeast Iran). Fungal colonies with similar colony colour were isolated from symptomatic tissues. The identity of the causal agent was determined as Neofusicoccum parvum, based on a polyphasic taxonomic approach including morphological features of conidiomata and phylogenetic inference based on the ITS‐rDNA region and translation elongation factor 1 alpha (tef1‐α) gene. Koch's postulates were fulfilled using an excised shoot method. This study provides the first report on the occurrence of N. parvum as a cause of branch canker on pomegranate in Iran. 相似文献
