结果： 1。从植物A的80％乙醇提取物中共分离得到16个化合物，分别为：-落叶松脂醇、-异落叶松脂醇、异落叶松脂醇9-O-β-D-吡喃葡萄糖苷、tanegoside B、芹菜素、芹菜素7-O-β-葡萄糖苷、芹菜素7-O-β-新橙皮糖苷、槲皮素3-O-β-D-吡喃葡萄糖苷、1，7-二羟基-3，4-二甲氧基-口山酮、菝葜皂苷元-3-O-[α-L-吡喃鼠李糖基（1-4）]-β-D-吡喃葡萄糖苷、喹诺酸3β-O-D-葡萄糖苷、知母宁、3′-对羟基苯甲酸-知母宁、大黄素甲醚、苯甲醇-β-D-吡喃葡萄糖苷、香草酸。

Pinoresinol diglucoside of Eucommia ulmoides could decrease with increasing of temperature and time.

随着炮制品的温度升高和时间的延长，杜仲中松脂醇二葡萄糖苷含量逐渐下降。

Methods: The changes of the content of pinoresinol diglucoside, extract and fingerprint were studied.

通过杜仲盐制前后松脂醇二葡萄糖苷的含量、醇溶性浸出物以及指纹图谱的变化进行比较研究。

METHODS Orthogonal design was used as the method of optimizing processing and pinoresinol diglucoside was assayed by RP-HPLC.

用正交设计法优选炮制工艺，采用RP-HPLC法测定松脂醇二葡萄糖苷的含量，作为杜仲质量控制的考察指标进行实验比较。

RESULTS The optimized processing was: salt dosage of 2.5%,temperature of 135℃, frying time of 30 min. Pinoresinol diglucoside of crude Eucommia ulmoides was twice of processed product.

结果 杜仲的最佳炮制工艺：用盐量2.5%、温度135℃、时间30 min，杜仲生品中松脂醇二葡萄糖苷含量高于炮制品2倍以上。

Results: Pinoresinol diglucoside contents in post-processed pieces were lower than those in pre-processed and aleohol extract had different changes because of its different habitats.

结果：杜仲盐制后松脂醇二葡萄糖苷的含量均有不同程度的下降，醇溶性浸出物因产地的不同而呈现出不同的变化趋势，杜仲指纹图谱共标出指纹峰11个，盐杜仲则标示出8个。

OBJECTIVE To choosing pinoresinol diglucoside as quality control index, to screen and optimize the traditional stir-frying with salt-water processing techniqul of Eucommia ulmoides, and compared with crude Eucommia ulmoides.

目的 以松脂醇二葡萄糖苷的含量为质控指标，筛选优化传统盐炙杜仲的炮制工艺，并与生杜仲进行比较。

A technological process for the extraction and purification of pinoresinol diglucoside in eucommia ulmoide oliver was studied andHPLC method for determination was used.

摘 要：对杜仲中活性成分松脂醇二葡萄糖甙(Pinoresinol DiGlucoside ，即PDG)提取、纯化工艺进行了研究，并使用高效液相色谱法测定PDG含量。

Walking through pinewoods, the summer air still and heavy with the scent of resin, eager feet sinking in soft white sand.

徒步穿过松林，夏日的空气静谧又凝滞，带着松脂的沁醇。双脚迫不及待地踩进洁白柔细的沙中。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
