丹东海域速生经济海藻无机营养元素的分析 总被引：1，自引：0，他引：1
张雅琴 《辽宁科技学院学报》2014,(2):20-21
对比了采自丹东沿海的12种速生海藻的无机营养元素的含量,并针对不同生长时期、不同产地对分属于不同门类的海藻富集无机元素的能力进行比较。结果表明：12种海藻常量元素和微量元素含量都十分丰富;K、Ca富含于褐藻门;Fe、P、Cu富含于绿藻门中,而红藻门的Mn、Zn含量最高。海藻吸收无机元素的能力与海藻种类、生长时期及产地有关。 相似文献

In the present study, the effect of red (Gracillaria corticata), green (Ulva fasciata) and brown (Sargassum ilicifolium) seaweeds alcoholic extract, against five important human cancer cell lines (MCF-7, MDA-MB-231, HeLa, HepG2, and HT-29) proliferation, apoptosis and cell cycle arrest were evaluated. The reducing activity and total polyphenol content were also investigated. MTT assay was used for cytotoxicity test. Morphological alterations were examined using phase contrast, fluorescent and electron microscopy. All the extracts were antiproliferative against all the cancer cell lines, dose-dependently, with G. corticata methanol extract (GCME) having the greatest inhibition activity against MCF-7 cell line. The percentage of apoptosis increased from 18 to 78 %. The cell cycle analysis also showed that GCME can induce apoptosis which confirm by TEM. Algal extract reducing activities were as follows: G. corticata > S. ilicifolium > U. fasciata. The GCME is a good source of potential complementary and alternative functional food for prevention and treatment of cancer. 相似文献

分析了采自大连沿海的13种速生海藻的无机营养元素的含量，并针对不同生长季节，不同海域对分属于不同门类的4种海藻富集无机元素的能力进行比较，结果表明：13种海藻中均含有钾、钙、磷等常量元素和铁、锰、铜、锌等微量元素，其中，褐藻门的钾、钙含量最高，绿藻门的磷含量最高，微量元素中，绿藻门的铁、铜含量最高，而红藻门的锰，锌含量最高，海藻富集无机元素的能力与海藻种类，生长季节及海域有关。 相似文献

Seaweed has been used in traditional cosmetics and as a herbal medicine in treatments for cough,boils,goiters,stomach ailments,and urinary diseases,and for reducing the incidence of tumors,ulcers,and headaches.Despite the fact that seaweeds are frequently used in the practice of human health,little is known about the role of seaweed in the context of inflammation.This study aimed to investigate the influence of Jeju endemic seaweed on a mouse macrophage cell line(RAW 264.7) under the stimulation of lipopolysaccharide(LPS).Ethyl acetate extracts obtained from 14 different kinds of Jeju seaweeds were screened for inhibitory effects on pro-inflammatory mediators.Our results revealed that extracts from five seaweeds,Laurencia okamurae,Grateloupia elliptica,Sargassum thun-bergii,Gloiopeltis furcata,and Hizikia fusiformis,were potent inhibitors of the production of pro-inflammatory mediators such as nitric oxide(NO),prostaglandin E2(PGE2),interleukin-6(IL-6),and tumor necrosis factor-α(TNF-α).Based on these results,the anti-inflammatory effects and low cell toxicity of these seaweed extracts suggest potential thera-peutic applications in the regulation of the inflammatory response. 相似文献
