We Factory export forest products as follows:Gum Rosin,Gum Turpentine(All products take to make by best,advanced and universal's a spectrum of steam method,and we severely differentiate material make into 100% Pinus Massoniana,Pinus Marsh,pinus elliotiis and Pinus mixed etc foru products),Pine Oil,Terpineol,α-Pintene,β-Pintene any rosins,Tung Oil,Cassia,Star Aniseed etc.our export have exceed 15years.

我司经常出口的林化产品有：脂松香、脂松节油（全部采用当前中国最先进和常用的连续蒸汽法生产，并严格区分原料生产出纯马尾松、湿地松、南亚松经合松四种产品）、松油、松油醇、α-蒸烯、β-蒎烯、各种树脂产品以及桐油、桂皮、八角等。其中，脂松香和脂松节油是我们的传统出口产品，已有15年的历史了。

Their structures were characterized as dihydroconiferyl dihydro-p-coumarate, vanillin, apocynin, p-hydroxybenzaldehyde, syringaldehyde, syringic acid, syringylethanone,α-hydroxypropiosyringone, coniferyl aldehyde, dihydroconiferyl alcohol, 2-hydroxyphenylpropanol, and 3-hydroxy-4-methoxy-phenylethanol, respectively.

结果 从该植物中分离得到12个酚性化合物，其结构分别为二氢松柏醇二氢对羟基桂皮酸酯，香草醛，罗布麻宁，对羟基苯甲醛，丁香醛，丁香酸，丁香乙酮，α-羟基丁香丙酮，松柏醛，二氢松柏醇，2-羟基苯丙醇和3-羟基－4-甲氧基苯乙醇。

Gallnut decoction group, was effective on eliminating Enterococcus faecalis when the pastes were placed 3 days ;until the pastes were placed 7 days , Enterococcus faecalis was successfully killed, although not as quickly as the other three drug groups.

五倍子水煎剂组，在第3天时可以抑制粪肠球菌，但不能完全杀灭；在第7天时，可以成功杀灭粪肠球菌；其效果不及桂皮醛组、 FC 组、氢氧化钙丙二醇糊剂组迅速。

Department of tooth crowns were removed and apical, dedicated root 6mm long, 50 teeth set up Enterococcus faecalis after root canal infection model, 20 teeth were placed in root canals cinnamaldehyde, gallnut decoction, Another 30 infected root canals placed FC, calcium hydroxide paste propylene glycol and normal saline.

标本牙去除牙冠部及根尖部，留取6mm长牙根，50颗牙建立粪肠球菌根管感染模型后，20颗牙根管内分别放置桂皮醛、五倍子水煎剂，另30颗感染根管放置FC、氢氧化钙丙二醇糊剂和生理盐水。

Condensation of cinnamaldehyde with methyl crotonate in the presence of alcohol-flee potassium methoxide gives,after hydrolysis,p-phenyl-benzoic acid in low yield.Its structure has been ascertained by direct comparison with an au- thentic sample.

桂皮醛与α-丁烯酸甲酯在催化剂去醇的甲氧基钾影响下进行反应，得到低产率的对-苯基-苯甲酸，共结构经用已知方法所得同样的酸直接加以比较而确定。

Methods: 60 freshly extracted , single-rooted premolars were randomly divided into two experimental groups (cinnamic aldehyde, gallnut decoction) and four control group (FC group, calcium hydroxide mixed with propylene glycol group, negative the control group and positive control group),.
