Koidz.with petroleum ether refluxing extraction,and the chemical constituents of fatty acids were analyzed by means of GC-MS.The yield rate of the oil was 36.7%.Main compounds of fattyacids were 13-octadecenoic acid,linoleic acid,hexadecanoic acidand octadecanoic acidwith relative contents of 40.5%,29.6%,24.8% and 5.1% respectively.The unsaturated fatty acids accounted for 70.1%.展开更多
以三叶木通(Akebia trif olia ta K o idz.)的新鲜叶片和硅胶干燥叶片为材料,分别采用CTAB法、高盐低pH法和苯酚法3种不同方法提取其植物总DNA,用琼脂糖凝胶电泳和紫外分光光度法检测获得的DNA的质量,以期从中找出提取三叶木通植物总DN...以三叶木通(Akebia trif olia ta K o idz.)的新鲜叶片和硅胶干燥叶片为材料,分别采用CTAB法、高盐低pH法和苯酚法3种不同方法提取其植物总DNA,用琼脂糖凝胶电泳和紫外分光光度法检测获得的DNA的质量,以期从中找出提取三叶木通植物总DNA的最适方法。结果表明对于三叶木通的新鲜叶片和硅胶干燥叶片,无论从产率上还是质量上,CTAB法都明显优于其他两种方法。展开更多
