Comparative analysis of alkaloid content determination and abirritation of anhusuo both before and after its preparation 延胡索炮制前后生物碱含量测定及镇痛作用的对比研究
The fumarate ion participates in several important metabolic pathways , e . g . the krebs cycle , purine pathways , and the urea cycle 延胡索酸分别参与多种重要的代谢途径,如卡尔文循环、嘌呤途径和尿素循环。
Results : the optimum extraction process was as follows , adding 8 times of 50 % alcohol into coptis meal , refluxing and extracting for 2 times , one hour every time 结果:最优提取工艺为中等粒度的醋延胡索, 50 %的乙醇, 8倍溶剂量,提取2次,高温减压浓缩。
But , the contents of essential oil in corydalis straminea maxim is simpler than that one , most of their chemical contents are long - chain alkylations , whose c are from 15 to 36 通过分析比较灰绿黄堇和草黄堇生物碱、延胡索乙素含量、挥发油含量及成分分析等方面的异同,为它们的开发利用提供科学依据。
Methods : using orthogonal design method , to apply extract yield of rhizoma coptis and the extract amount of berberine hydrochloride as observing indexes , to measure the content of dl - tetrahydropalmatine with hplc 方法:采用正交设计法,以槲皮素、原儿茶醛薄层斑点,延胡索乙素含量为指标,优选提取工艺。
Abstract : the pollen morphology of 5 species of corydalis from northeast china was observed and compared by sem . the results declared the shape and size of the pollen and exine sculpture of the 5 species were basically stable and could serve as a taxonomic character 文摘:用扫描电镜对东北延胡索极其近缘植物的花粉形态进行了观察,结果发现花粉粒在形状、大小、外壁纹饰、沟的长短及宽度等方面均有区别,从中获得了东北延胡索及其近缘植物分类方面的孢粉学依据.因此花粉的特征可用于区别延胡索类植物
