At present, production and processing of amygdalin in China domestic market is limited to a single product, and discarded other products. In particular, amygdalin is discarded as toxic substances. This is not only wasted the resources but also caused environmental pollution.

目前，我国市场对苦杏仁产品的生产加工仅限于单一产品的开发，而丢弃了其他副产品，尤其是将苯甲醛的前体物质苦杏仁甙作为有毒物质丢弃，不仅造成了资源的大量浪费也使环境受到污染。

The results indicated that the content of amygdalin, crude fat content, acid value , peroxide value and carbonyl value changed significantly.

对高温条件下苦杏仁品质稳定性进行了研究，结果表明：高温环境下苦杏仁中的苦杏仁甙含量、脂肪含量、酸价、过氧化值和羰基值发生明显变化，影响了苦杏仁品质。

A suitable method for extraction of amygdalin from hawthorn has been established. At first, the lipophilic components were removed with petroleum ether by ultrasonic extraction.

建立了从山楂中提取苦杏仁甙的方法，样品先用石油醚脱脂，然后用甲醇进行索氏提取。

Objective To study the effects of tetrandrine, tetramethylpyrazine and amygdalin on activity of collagenase secreted by human kidney fibroblasts, proliferation, apoptosis and expression of type Ⅰ collagen of human KFB.

目的 观察汉防己甲素、川芎嗪和苦杏仁甙3种中药成分对人肾成纤维细胞的影响。

Sixty Wistar rats were randomly assigned to receive sham operation, blockage of unilateral ureteral without treatment, or intraperitoneal injection of amygdalin at a dose of 3 mg or 5 mg, and then sacrificed on days 7, 14 and 21 postoperatively, Pathological changes in the kidney in each group were observed.

用单侧输尿管梗阻的方法建立大鼠肾脏间质纤维化模型。60只Wistar大鼠随机分为假手术组、单侧输尿管梗阻组、苦杏仁甙3 mg腹腔注射组和苦杏仁甙5 mg腹腔注射组，分别于术后7、14、21 d处死动物，观察各组大鼠肾脏病理损害程度。

It can be concluded that the content of amygdalin is higher in the seeds than that in the hawthorn powder without the seeds and the yield of amygdalin is higher in the hawthorn pieces than that in the hawthorn powder.

测定了含不同比例山楂籽的山楂样品，结果表明含山楂籽比例高的山楂样品中苦杏仁甙的含量高，且山楂粗粒样品中苦杏仁甙的提取量比粉末样品的提取量高。

Bitter almond contains amygdalin and almond oil, amygdalin can be decomposed to benzaldehyde under acidic condition, benzaldehyde is one of the most widely used flavor in fragrance industry. Almond oil contains high contents of unsaturated fatty acids and VE, it is an advanced edible oil, also can be used in cosmetics materials.

苦杏仁含有2-4%的苦杏仁甙，苦杏仁甙在酶或酸的作用下水解后产生具有强烈的杏仁香气的苯甲醛—即苦杏仁精油的主要成分；另外，苦杏仁含有约50%左右的脂肪油，苦杏仁脂肪油含有大量不饱和脂肪酸以及VE，可直接作为高级食用油或高级化妆品的原料。

And the main constitute of almond essential oil in experiments was benzaldehyde examined by ultraviolet spectrophotometer.

但目前国内对苦杏仁的研究主要集中在杏仁油和苦杏仁甙的开发利用上，而对苦杏仁挥发

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
