The chemical composition research aspect literature report are extremely few: According to reports, the root of Rosa davurica pall includes the lactone, the tanning substance, the return to original state sugar, the total lucoside, the flavanone, the phenol class, the biological alkalis, the protein, the anthraquinone equi com ponent, moreover ,the total polysaccharide is the even polysaccharide which is composed by the fructose.In 1999, for the first time from puncture the root in the alcohol extraction to sep arate Oleanic acid. And used the double wave length thin layer scanning method to determine the uneven pillar tartaric acid in to puncture in the root ontent.

化学成分研究方面文献报道极少：据报道，山刺玫根中含有内酯、鞣质、还原糖、总苷、黄酮、酚类、生物碱类、蛋白质、蒽醌等成分，而且山刺玫根中总多糖是由果糖组成的均多糖。1999年，首次从刺玫根的乙醇提取物中分离出齐墩果酸，并采用双波长薄层扫描法测定了齐墩果酸在刺玫根中的含量。

METHODS The contents of synephrine,neohesperidin,hesperidin, naringin and narirutin in the raw materials and the extracts of Citrus aurantium were determined by reversed-phase high performance liquid chromatography with an Inertsil ODS-3(4.6 mm×250 mm,5 μm) column, respectively.

方法采用高效液相色谱法，以InertsilODS-3(4.6mm×250mm，5μm)色谱柱分别对枳实及其提取物中辛弗林生物碱类成分和新橙皮苷、橙皮苷、柚皮苷、芸香柚皮苷黄酮类成分进行测定。

Benzimidazoline as a new tetrahydrofolate coenzyme model to perpare alkali can bring a byproduct N, N\'-dimethylaniline, this byproduct can be recycled to produce benzimidazoline as raw materials.

这种新的仿生合成方法，以羧酸和卤代物为起始原料制备四氢-β-咔啉类化合物，可为工业生产β-咔啉类生物碱提供更为方便的条件。

Quinazolinone alkaloids are the active components contained in the plants of Rutaceae. Many investigators have indicated that quinazolinones have anti-tumor activity. However, the reasons why the molecular mechanisms of quinazolinones produced their biological effects remain unknown.

喹唑啉酮类生物碱是芸香科植物中所含的活性成分，虽然已有许多研究者证实喹唑啉酮类缘物具有抗癌活性，然而，其真正的抗癌作用机制仍然未被厘清。2-(Naphthalene-1-yl)-6-pyrrolidinyl-4-quinazolinone（HL66）是合成的喹唑啉酮类缘物。

The 3,4-disubstituted succinimide substructure-containing natural products andindolizidine alkaloids, tropane alkaloids are widespread in nature. Most of themexhibit important bioactivities.

含有3，4-二取代琥珀酰亚胺结构的天然产物以及吲哚里西啶生物碱、托品烷类生物碱广泛分布于自然界中，它们大多具有重要的生物活性。

We provided biomimetic synthetic methods for tetrahydro-β-carboline by using the benzimidazoline as a new tetrahydrofolate coenzyme model with tryptamine as nucleophile reagents under the condition of acid.

由四氢-β-咔啉类化合物，可制得多种具有较好抗病毒、抗菌和抗肿瘤活性的β-咔啉类生物碱，因而四氢-β-咔啉类化合物的合成受到人们的广泛关注。

Results: Adsorption capacity of congenial adsorbents in macroporous adsorbing resins of different types was significantly different.

结果：复方中黄酮类和生物碱类成分在不同型号大孔树脂上的吸附容量有明显差异。

Result: The lipo-alkaloids were decomposed under high temperature and pressure, also produced the corresponding hydrolyzing alkaloids.

结果：脂类生物碱在高温高压条件下发生分解反应，生成相应的水解型生物碱。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
