韭菜

Objective: To extract the volatile oil from rhizome,leaf,flower of chive by chemical method and its chemical components were identified.

目的 ：用化学方法从韭菜的根茎、韭菜叶、韭菜花中提取挥发油，并鉴定出其挥发油的化学成分。

However, There is not the report about the effects of nitrogen on yield, quality and key enzymes in nitrogen metabolism of Chinese chive in a hydroponics system.

本试验以6韭菜品种为试材，研究了氮素营养对韭菜生理效应、氮代谢关键酶及硝态氮对不同韭菜品种的根系生长的影响，以期为韭菜低硝酸盐富集品种的选育及无土栽培提供理论依据。

The results showed that phosphorus deficiency stress environment (0~80 μmol/L) and phosphorus abundance stress environment (160~320 μmol/L) made the content of Chl a, Chl b and the total content of chlorophyll decline obviously, and restrained the growing of Chinese chive and decreased the yield.

结果表明：低磷胁迫(0~80μmol/L)和高磷胁迫(160~320μmol/L)使韭菜叶片的叶绿素a、叶绿素b及叶绿素总量明显下降，抑制韭菜的生长，降低了产量。

Cabbage leaves with the chives, then wrapped in leek was not easy to evaporate the water, but also ...

用白菜叶把韭菜包起来的话韭菜的水分也不容易蒸发，而且还能。。。

The results showed that the total phosphorus concentration had close relation with the irrigation interval of leek field.

结果表明。福保村韭菜地排水边沟中总磷浓度和韭菜地的灌溉周期密切相关。

Based on the biology model, leek is put in the normal paint or water-based environment. Since the ratio of microkernel is directly proportional to damage, the pollution can be assessed through the permillage of microkernel.

通过实验建立起生物学模型，将处于减数分裂时期的韭菜花放入涂有油漆和水性漆的环境中，其花粉细胞常发生突变，而在正常环境中的韭菜花的花粉细胞突变较少。

Medthods:Volatile oil of chive was extracted by means of water-vapour distillation and its chemical components were assayed by capillary gas thromat ography-mass spectrometry.

用水蒸气蒸馏法提取韭菜中韭菜的根茎、韭菜叶、韭菜花挥发油，并用毛细管气相色谱/质谱法，鉴定出其挥发油的化学成分。

For confirmation of this ancient legend and found out the sexual improvement compounds the testosterone and NO in serum of mice were measured,the weight of sexual organs of mices was detected and the sex behaviour of mice was observed.The testosterone and NO concentration in serum of mice as indicator for screening some improving sexual compounds from Chinese chives was builted.1、The preliminary experiment of Chinese chives confirm sexual improvement functionThe sexual improvement function experiments of Chinese chives comparing with herba epimedii,herba cynomorii and radices morindae which were acknowledged as chinese herbals having sexual improvement function were carried out.The result was showed that the Chinese chives was confirmed having sexual improvement function,though its efficacy was less than herba epimedii,herba cynomorii and radices morindae.

为了证实古代医学认为韭菜的壮阳功能，揭示韭菜起温肾壮阳作用的化学物质基础，开发其功能性物质成分，本实验首先应用韭菜酒精初提液对小鼠睾酮、NO含量、性器官、性行为等指标的测定，验证韭菜是否具有改善性功能作用，然后以小鼠睾酮、NO含量等为指标对韭菜中的壮阳物质进行逐步分离和改善性功能作用筛选，以鉴定出几种改善性功能的物质。1、韭菜改善性功能的验证将韭菜与淫羊藿、琐阳、巴戟天三种有温肾补养功能的中草药进行比较，发现韭菜改善性功能作用不如淫羊藿、琐阳、巴戟天壮阳中草药的效果明显，但是韭菜还是具有显著的改善性功能作用的(P＜0.001)。

The concents of testosterone and NO of the mouses gavaged with high dosages of Chinese chive extractiong were not significantly more than that of giving middle dosages.This indicated that Chinese chives might be more safe than traditional chinese herbals of sexual improvement function.2、The screening of sexual improvement function chemical substances of Chinese chivesThe crude extract was leached to four phases by petroleum ether, ethyl acetate,n-butanol and water.By doing animal tests to detect the contents of testosterone and NO in serum of mices,the result was showed that the extracts of petroleum ether and n-butanol have sexual improvement function,especial the n-butanol phase.

从小鼠灌喂不同剂量的韭菜提取液试验结果来(来源：ABCa539a5论文网www.abclunwen.com)看，灌胃高剂量的小鼠的睾酮含量和NO含量相对于中剂量来说并不上升，而是保持稳定，因为睾酮含量和NO含量过度上升可能会带来付作用，所以由此可以说明其食用安全性高，副作用小。2、韭菜改善性功能物质的筛选将韭菜粗提物依次通过不同溶剂萃取，分成石油醚、乙酸乙酯、正丁醇和水四个萃取相，通过小鼠灌胃的动物试验，以小鼠血液NO含量和睾酮含量为指标，发现正丁醇和石油醚萃取相中的物质有改善性功能的效果，尤其是正丁醇相效果非常显著。

Leeks, green onions, garlic Even if these three do not you like to eat: Because leeks will be glued to the teeth, the teeth white with green leek Road is not a good scene; green onions and garlic odor of the president of the stay in your mouth and stomach, the girls hate this taste comparison.

韭菜、大葱、大蒜这三样就算你再喜欢也不要吃：因为韭菜会粘在牙上，白色的牙齿配上绿色的韭菜可不是道良好的风景；大葱和大蒜的气味会长久留在你的口腔和肠胃中，女孩子比较厌恶这种味道。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
