The contents of total flavonoids and triterpene are detected with the weight method.

是我国药典记载的药用甘草[ 1 ]，其主要有效成分是皂甙类、黄酮类、生物碱和多糖类化合物。

The structures of the triterpene glycosides were elucidated based on spectral data, chemical reactions, and related references.

利用大孔树脂柱层析、正相硅胶柱层析、反相硅胶柱层析、Sephadex LH-20以及HPLC等层析手段，对一种辐肛参的皂苷类成分进行分离，应用波谱技术和化学方法，并结合文献对照，对所得的化合物进行结构鉴定。

Furthermore, a series of triterpene glycosides that composed of oleanolic acid, ursolic acid and glucosamine oligosaccharides were synthesized, and their structures were determined.

本文还以具有良好生物活性的五环三萜类的化合物齐墩果酸与熊果酸作为苷元，完成了一系列氨基葡萄糖及其寡糖三萜皂苷的合成和结构确定工作，为测试其生物活性、研究构效关系奠定了基础。

Firstly, the homopolymerization of acrylamide was carried out in aqueous phase by reversible addition-fragmentation chain transfer radical polymerization using a trithiocarbonate as a chain transfer agent.

整个过程分为两步，首先在水溶液中，通过RAFT控制得到亲水性单体丙烯酰胺的均聚物；然后以得到的均聚物作为水溶性的大分子链转移剂，在水相中条件下参与亲油性单体苯乙烯无皂乳液聚合。

The fatty acid in tussore oil was saponificated and modified to methyl esters by different means .

研究了脂肪油的衍生化、三氟化硼、硫酸3种不同方法对脂肪油的皂化、甲酯化效果，并用GC/MS法对柞蚕中脂肪酸的成分进行了鉴定和分析。

They were never thoroughly removed in the first place and the soaps used and/or the uncleaned sticky substance collects more dirt; or 2 The unwanted material is forced down below the surface of the carpet by a high pressure steam cleaning unit - only to "wick" back up as the carpet dries.

有两个原因可以使污点在清洗后重现：1）、没有完全去掉污点，并且清除污点所用的皂剂和没有清洗掉的粘性物质吸引了更多脏的东西。2）、污垢在高压力下被打到地毯深处——干燥过程中又泛上来

In this article, three representative oil and fat resourse (edible raw oil, unedible linseed oil and waste oil and fat) were used to study the fatty acid methyl ester preparation technology, and the products from different technologies were compared and analysed. For plant oil, ester exchange process was performed immediately after simple decolorating and alkali refining pretreatment.

对于植物油脂，采用简单的脱色、碱炼预处理后，直接进行酯交换的工艺；对于废油脂，由于其成分变质较严重，预处理也显得相对复杂，采用了先预酯化再酯交换的工艺和先皂化酸化后再酯化的两种工艺。

Margarine Unie, a Dutch producer of margarine, and Lever Brothers, a Britishsoapmaker.

合并的双方是荷兰人造黄油生产商玛格瑞乃公司，和英国制皂商利华兄弟公司。

It is mainly from a higher degree of unsaturated fatty acid composition of甘油脂, in addition to small amounts of phospholipids and unsaponifiable matter.

它主要由不饱和度较高的脂肪酸甘油脂组成，此外还有少量的磷脂和不皂化物。
