AbstractObjectiveTo analyze the constituents of the essential oil from fresh Canarium album Raeusch leaves.Methods Essential oil from the fresh Canarium album Raeusch leaves was extracted by steam distillation and were analyzed by gas chromatography-mass spectrometry (GC / MS). Results Forty-six
compounds were identified, which accounted for over 99.7% of the essential oil. Conclusion The main components of essential oil include trans-3-hexenol (36.58%), Alloaromadendren
(16.26%),. beta.-caryophyllene (6.51%), hexanal ( 5.66%),
isohexanol (4.92%) ,2-ethoxypropane (4.78%), cis-2-peneten-1-
ol (3.10%), cis-3-hexenyl acetate (2.89%), methyl salicylate (2.32%) and etc.

Olive Branch plant olive Canariumalbum (Lour.) Raeusch., For the tall trees, commonly known as the Green Lam, white rugby and so on, originated in China and in Fujian, Guangdong, Guangxi, Taiwan, Yunnan, Sichuan and other provinces for many in our country has 3000 years of cultivation history; stone circle moment for the Egg, was green when ripe, so called "fruit." According to "Compendium of Materia Medica" contains: "Olive to Health fluid, only polydipsia, cure sore throat, chemical product fresh. Chew swallow juice can answer all
Yubie poison." Olive (fruit) can rule carnivorous fish bone stuck throat and poisoning can also hangover drugs to reduce cholesterol. Yan-Ling Liang et al  reported that olive plants of Ukraine Lam Canarium pimela Koening leaf water
extract with a step-down and slow down the heart rate
Pharmacodynamics. Green Lam fruit volatile oil components have been reported in the literature [2,3], green leaf volatile components Lam reported in the literature yet to see. In this study, extracted by steam distillation of fresh olive leaf volatile oil, gas chromatography - mass spectrometry analysis
of fresh olive leaf volatile components were analyzed.
1 Materials and methods
1.1 sample sources and the extraction of volatile components in samples collected from Guangdong Longmen Nankunshan feet, age about 180 years of fresh fruit olive leaves. The fresh olive leaf crush, saying that taking 200 g, using steam distillation 3 h, distillate extracted with anhydrous ether, extract dried with anhydrous sodium sulfate,
35 ? water bath, vacuum recovery ether, had orange ribbons there are micro-Xin Lam smell fragrant volatile oil 0.052 g, have the oil rate of about 0.026%. Analysis of volatile oil from pre-airtight container stored at 10 ? below. Anhydrous
ether and anhydrous sodium sulfate were of analytical grade reagents.

2 Results and discussion
Figure 1 is a fresh olive leaf volatile oil composition of the total ion chromatogram, a total of 49 isolated peaks, using a computer search of all peaks corresponding mass map identified 46 compounds, with peak area normalization method
was determined by their The relative content. The results in Table 1. Volatile components were identified accounting for 99.7% of the total composition.
Table 1 data show that the volatile components of fresh olive leaves are mainly alcohols, terpenes, aldehydes, ketones, esters, and most also contain unsaturated bonds, such as: enol type, allyl aldehyde, allyl esters and other substances. Of fresh olive leaf volatile components in the
methyl salicylate has a fragrant smell, as a traditional folk medicine for pain and convergence, pass through, Qufeng, urination, excitement and so on efficacy for the treatment of headache, abdominal pain, joint pain, inflammation, rheumatism, sore throat, skin diseases, dental conditions such as wind ; β-elemene with a broad-spectrum anti-tumor,
curative effect, drugs, mild side effects, etc., to β-elemene
as their principal ingredients Eiemene injection is the success of China's independently developed Type II anti-tumor
drug, is currently widely used in clinical malignant serous effusion, lung cancer, gastrointestinal cancer, brain tumors and other treatment of superficial tumors [5 ]; Caryophyllene is the main component of natural flavors and fragrances. We
hope that the volatile components of fresh olive leaf's study can in order to better development and utilization of resources to provide a scientific basis olive leaf. Table 1 fresh olive leaf volatile oil chemical constituents and their
