水杨梅

Taking the ampelopsis as the raw material,under the condition that ethanol soaks to prepare the processing,taking water as the associated extract dihydromyrictin.

以干藤茶叶为原料，采用乙醇浸泡进行预处理，以水为溶剂提取二氢杨梅素，考察了乙醇预处理时间、茶叶与乙醇的料液比、加热时间等因素对提取率的影响，通过单因素分析和正交试验设计，确定了最佳提取工艺条件。

Result The number of diarrhea in each group administered bayberry extracts was reduced, with the effect of the ethanol extract being stronger than that of water extract.

结果 灌胃杨梅果实提取物的小鼠的腹泻次数均有明显的下降，且醇提物的作用效果要好于水提物。

Heat value relates to lignose content and benzene-ethanol extractive content linearly.(3) Of all the 12 tree species,Schima superba, Castanopsis hystrix, Myrica rubra have the strongest resistance to fire; Machilus pauhoi, Mich elia macclurei, Mytilaria laosensis, Camellia olifera and Manglietia tenuipes are relatively strong in fire-resis tance, and Lithocapus thalassica, Tsoongiodendron odorum, Cunninghamia lanceolata and Pinus massoniana are weak in fire-resistance.

木质素含量和苯-乙醇抽取物与总发热量有线性相关关系；(3)由多目标决策方法对12种树的抗火性能综合排序，木荷、红椎、杨梅的抗火性强，刨花楠、水老排、火力楠、油茶和木莲的抗火性中等，稠木、观光木的抗火能力较弱，杉木、马尾松的抗火能力弱。

［Objective］ To research main compounds in different fractions of water extract from the root of Adina rubelle Hance.

［目的］研究水杨梅根提取物不同提取部位的主要成分。

Organic solvent repetition crystallization method showed that 60% ethanol was the suitable solvent system. After 5 times repetition crystallization, the purity of product can be up to 98%, and the crystal state was yellow club-shaped, length of which is above 3mm. The productivity of this method is 30.01±1.26%, which is 2 times high than water repetition crystal method. So this method has good exploitation foreground.

有机溶剂重结晶法，选择60%浓度乙醇为适合的二氢杨梅素结晶体系，经过5 次重结晶后，产品的纯度可达98%，晶体为黄色、棒状，长度可达3mm，结晶产率为30.01±1.26%，较水重结晶法高2 倍左右。

Unfortunately for the Bennets, if Mr Bennet dies their house will be inherited by a distant cousin whom they have never met, so the family's future happiness and security is dependant on the daughters making good marriages.

不幸地为水杨梅，如果Bennet先生死他们的房子将由他们从未遇见的一个远表兄继承，因此家庭的未来幸福和安全依靠做好婚姻的女儿。

But it would be unstable in water with the increasing of temperature and heating time, even be oxidated.

但在水相中随时间和温度的增加会变得不稳定。pH 值是影响二氢杨梅素稳定性的重要因素。

He and Nina moved to California and lived at 2005 Ivar Street, Apt.
