The contact toxicity of two kinds of bitter almond on Musca domestica vicina, Mythirmna separata and Sitophilus zeamais was studied. The result showed that the contact toxicity of bitter almond oil is stronger with the increase of concentration.

含有和去除HCN的苦杏仁精油对家蝇、粘虫以及玉米象的触杀活性结果表明随着浓度的增大，精油对三种试虫的触杀活性增强。

The result showed that there was significant botanical character difference among the three varieties of rosemary; the content of essential oil of Rosmarinus officinalis L is higher than that of Rosmarinus officinalis 'Rex' and Rosmarinus officinalis 'Wood' with 0.80, 0.46 and 0.40 mL(100g)^(-1)FW respectively;α-pinene、1,8-cineole、verbenone、geraniol and borneol were the main compositions of essential oil from Rosmarinus officinalis L, with 27.26%, 20.92%, 11.75%, 5.92% and 5.07% respectively; the major components of essential oil of Rosmarinus officinalis 'Rex' were 1,8-cineole、camphor、borneol、α-pinene and camphene, accounting for 31.07%, 21.66%, 11.98%, 5.36% and 5.34% respectively; in Rosmarinus officinalis 'Wood', camphor、1,8-cineole、bornyl acetate、borneol、α-pineneand camphene were the major compositions with 24.69%, 23.96%, 6.76%, 5.94%, 5.80% and 5.28% respectively.

结果表明：三种迷迭香的植物学性状，如外形、花色等差异显著；迷迭香的精油含有率较高，为0.80mL(100g)^(-1)FW，Rex迷迭香和Wood迷迭香的精油含有率低，分别为0.46和0.40mL(100g)^(-1)FW；迷迭香的主要成分为α-蒎烯27.26%、1，8-桉叶素20.92%、马鞭烯酮11.75%、香叶醇5.92%、龙脑5.07%等，Rex迷迭香精油中1，8-桉叶素31.07%、樟脑21.66%和龙脑11.98%、α-蒎烯5.36%、莰烯5.34%是其主要成分，Wood迷迭香精油的主要成分为樟脑24.69%、1，8-桉叶素23.96%、醋酸龙脑酯6.76%、龙脑5.94%、α-蒎烯5.80%和莰烯5.28%等。

In this thesis we carried on the preliminary study to the extraction process of plant essential oil, and measured the biological activity of plant essential oil on red flour beetle, Tribolium castaneum and the housefly, Musca domestica vicina.

采用三因素四水平正交试验设计对植物精油进行提取工艺研究，最佳提取工艺条件是A_2B_3C_3，即50g供试植物加入1000ml水，水蒸气蒸馏120min后，用石油醚萃取，萃取液浓缩以后得到的精油可获最大收益。

First talk about price,price is about who would take the refined oil rose to an example,extract adrop of rose oil to 2000flowers,rose flowers yield about 500-750kg,in the international market price of Bulgarian rose oil also in the 6~8USD/kg is usually between.a rose flower oil rate for extreme III and,thus 10ml100%Rose oil prices for tho西方强国nds or even tens of tho西方强国nds.

起首讲一下价格，谈到价格很人城市拿玫瑰精精油来举例，提取1滴玫瑰油要2000朵鲜花，玫瑰的鲜花亩产约500-750kg，在国际市场上保加利亚玫瑰精油价格也就在6~8美元/kg之间。通常玫瑰鲜花的出油率为万分三，因此10ml100%玫瑰精油价格都要上千甚至上万。

The contents are mainly divided into three parts: The first part describes mechanism and metabolism rule of natural products and its classification ; The second part is about the growth and development of plants and their mutual relationship, natural biological active substances which are produced in the course of defending plant diseases and insect damages. The third part is not only the function and principle of medicine, anticancer and antioxygen activity of different kinds of natural products such as resin ,essential oil, high molecule, grease and so on but also their application. The fourth is security problem of Plant Natural Products. Through the lessons, we can correctly understand and use the relationship between plants and environment.

其课程分为13章，内容主要分为4大部分，一是阐述植物天然产物的发生机理和代谢规律，介绍相关主要植物种类，并对天然产物进行化学分类；二是讲述植物天然产物和自身生长发育之间的关系、天然产物如何影响植物之间的相互关系、以及植物如何利用天然生物活性物质抵御病虫害的威胁；三是详细描述了各种天然产物，如植物自身生长发育过程中所产生的活性物质、植物与其它生物之间的相互关系中所产生的生物活性物质、植物毒性物质、植物药理活性物质、植物抗生物质、植物树脂、植物精油、植物高分子、植物油脂、植物抗氧化活性成分等，并阐述它们的药理活性、抗癌性、抗氧化性等对人类健康起作用的的功能和原理；四是提出了植物天然产物的安全性问题，并介绍相关案例和介绍相关法规；在此基础上还专门讲述了树脂、精油、高分子、以及油脂类等天然产物的应用。

When induced to differentiate in the presence of Oleaceae oil (35-130 mg/ml), 3T3-L1 preadipocytes dose- dependently reduced their ability to accumulate cellular triglycerides. Cytoplasmic triglyceride droplets could also be visualized by microscopic observation. Cells treated with 130 mg/ml Oleaceae oil retained their morphology as spindly fibroblasts, while normal adipocytes take on a rounded shape filled with triglyceride droplets.

在开始刺激细胞分化的同时，以 35 mg/ml 到 130 mg/ml 不同的木樨科精油浓度处理细胞，为期八天，将分化到第八天的细胞收下来测三酸甘油酯的浓度当作分化程度的指标，结果发现随著木樨科精油浓度的增加，细胞所累积的三酸甘油酯浓度就越低，用显微镜观察即可发现细胞中脂肪油滴所占的比例明显降低。

At the same time, the inhibition effect of plant essential oil to pathogenic fungi was determined.

三因素中萃取溶剂是提高精油产量最重要的因素，其次是蒸馏时间，加水量对精油的产量影响较小。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
