松脂

The ancient Egyptians could make glass, tile, turpentine, soap and dyes.

古埃及人制造了玻璃、瓷砖、松脂、肥皂和染料。

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。

The two compounds were confirmed as phillygenin and matairesinol and both were isolated from the P. granatum first.

结论］确定2个化合物分别为连翘脂素和罗汉松脂素，均为首次从该种植物中分离得到。

Such as thin lightweight precast concrete blocks, hollow clay blocks and timber studding covered with either plasterboard, fibreboard, matchboarding, plywood, chipboard, resin bonded blockboard or other form of cladding.

如用轻薄混凝土砌块、空心砖、细木条再覆以壁纸板、纤维板、假型板、胶合板、经纤化处理后的废纸板、松脂粘合板或各种类型的复合材料板等。

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。
