In the 1930s, the Russian geochemist/biologist Vernadsky wrote,"The property of maximum expansion is inherent to living matter in the same manner as it is characteristic of heat to transfer from more heated to less heated bodies, of a soluble substance to dissolve in a solvent, and of a gas to dissipate in space."

1930年代，俄罗斯地理化学/生物学家沃尔纳德斯基写道："最大化扩张的属性是活物与生俱来的，就如同热之从温度较高的物体传到温度较低的物体，可溶性物质之溶入溶剂，以及气体之消散入天空。"

The essential oil was prepared from the peel by solution extraction, and separated into fractions of hydrocarbon and oxygenated compounds through a silicagel column. As the oxygenated fraction had the characteristic aroma of the peel oil, odor quality of the fraction was estimated on the basis of a odor unit value. Twenty five compounds such as geranial, neral, linalool and aliphatic aldehydes were selected as the components contributed to the aroma of the peel oil.

用溶剂萃取法提取白柠檬果皮的精油，并用硅胶柱将精油分成碳氢化合物和含氧化合物两大部分，由于含氧化合物部分具有果皮油的特征香气，利用各成分的香气值对该部分进行了评价，明确了香叶醛、橙花醛、沉香醇以及一些脂肪族醛等25种成分对白柠檬果皮油香气起着重要作用。

Methods: In the presence of hydrochloric acid or nitric acid, geranyl sulfone was prepared from geraniol in isopropyl alcohol or THF under reflux conditions for 18 h or 28 h, respectively.

以异丙醇或THF为溶剂，盐酸或硝酸为催化剂，香叶醇与苯亚磺酸钠回流反应18或28 h得香叶基砜。

Germanium, solvent extraction method is a simple, rapid separation, and the most competitive method with good effect.

锗的提取中溶剂萃取是一种简单、快速分离、效果理想、最有竞争力的方法。

Experiment 3: Affections of Ginger Extraction on Cardiac Systolic/Diastolic Function of Rabbits with Heart Failure and the Comparison Between Ginger Extraction and 4-Retro-decoction (Si-hi Tang,四逆汤) Method 50 pure-breed New-Zealand rabbits were randomly allocated into 5 groups: control group, low (0.028mL/kg), middle (0.056mL/kg) and high (0.112mL/kg) dosage Ginger group, and 4-Retro-decoction group. The heart failure model of rabbit was established by intravenous administration of 20g/L pentobarbital sodium (0.15 mL·kg〓·min〓) at a certain rate. Oral tube perfusion of Ginger extraction was administrated after the establishment of the model. Their hemodynamic changes were detected before and after the model establishment, and at 5, 10, 15, 20, 30, 45, 60, 90, 120, 150 minutes respectively after the ginger administration by a RM-6000 4-graph physiological monitor.

干姜提取物对兔急性心衰模型心脏功能及血流动力学的影响及其与四逆汤作用的比较方法以50只纯种新西兰兔为研究对象，随机分为低、中、高剂量干姜组，溶剂对照组和四逆汤对照组，共5组，以0.15mL·kg〓·min〓静脉恒速给予20g／L戊巴妥钠的方法建立兔急性心力衰竭模型，造模成功后，经口插管入胃灌服受试品，用RM—6000四道生理仪测定造模前、造模成功时及用药后5min、10min、15min、20min、30min、45min、60min、90min、120min、150min兔的心肌舒缩性能指标，观察各时段指标的变化情况。
