| 2. | Chemical studies on sesquiterpenes in soft coral lobophytum sp . from the south china sea 中倍半萜化学成分的研究 |
| 3. | Two compounds with the purity higher than 95 % were obtained with this method 通过该方法,已得到两个二氢沉香呋喃倍半萜类化合物,纯度均在95 %以上。 |
| 4. | The gc / ms analyses of oil samples from qhd32 - 6 oilfield show that bicyclic sesquiterpanes are abundant 摘要色谱质谱分析结果表明,秦皇岛32 - 6油田原油中含有丰富的双环倍半萜。 |
| 5. | A novel 1886bp full - length sesquiterpene synthase ( ases ) cdna was cloned from a high - yield artemisia annua strain 001 by race strategy 用race方法从青蒿高产株系001中克隆了一个新的1886bp的全长倍半萜合酶cdna 。 |
| 6. | Conclusion the essential oil from d . dasycarpus . is mainly consisted of sesquterpenoids and aliphatic acids , and the sesquterpenoids is the main active component 结论白鲜皮挥发油主要由倍半萜类化合物和长链脂肪酸成分构成,而倍半萜类化合物是其主要活性成分。 |
| 7. | From gas chromatogram chart , in addition to less composition of volatile compounds , onion oleoresin contained more resin that has sharp flavor and pigment 从气相色谱图上可以看出,洋葱油树脂中除含少量洋葱精油外,主要是沸点较高的倍半萜及代表辛香味的树脂成分、色素等。 |
| 8. | The best method for isolation and purification of - dihydroagarofuran sesquiterpene in celastrus angulatus is alternate normal - phase and reserve - phase high performance liquid chromatography 结果表明,对苦皮藤中富含二氢沉香呋喃倍半萜类化合物部分进行分离的过程中,采用正相、反相高压制备柱层析交替进行的方法最为有效。 |
| 9. | In these bicyclic sesquiterpanes , the relative abundance of the rearranged drimane is regularly changed in spatial distribution , which may indicate the characteristics of petroleum migration and accumulation in qhd32 - 6 oilfield 该油田双环倍半萜中重排补身烷的相对丰度在纵向上和横向上都表现出有规律的变化,这种规律性的变化可能反映了秦皇岛32 - 6油田油气运移与聚集的特徵。 |
| 10. | Artemisinin , a sesquiterpene lactone containing an endoperoxide bridge , is a kind of phytoalexin . sa , a key signal molecular during systemic acquaired resistance ( sar ) , is related to the biosynthesis of phytoalexin . aba , a stress - resistance plant hormone can influence the secondary metabolism to stimulate phytoalexin biosynthesis 青蒿素属于萜烯类化合物(倍半萜类)是植保素( phytoalexin )的一种, sa是植物产生系统获得性抗性的重要信号分子,与植保素的产生相关。 |
