二苯乙烯

As for the forth part, the effects of microorganism on those stilbenoids other then piceatannol and resveratrol were discussed. Arachin derivatives, separated and identified by HPLC-MS, were corresponding to those stilbenoids found in callus.

第四部分则为以液相层析质谱分析鉴定落花生愈合组织中比杉特醇及白藜芦醇以外的类二苯乙烯化合物，结果发现有五个与 arachidin 结构类似之化合物。

The result shows that both of the two C-C double bond are exist as a trans configuration. The dihedral angle between benzene ring was 24.6°and 37.5°respectively.

发现均二苯乙烯荧光团的两个双键都是以反式结构存在，并且分子中的苯环并非完全共平面，相邻苯环之间的夹角分别为24.6°和37.5°。

Perhaps this is relevant to emodin and diphenyl ethylene glucoside which are the main ingredients included in the herb.

何首乌具有延年益寿，抗衰老作用，可能与其所含的主要成分大黄素、二苯乙烯苷有关。

Objective:To investigate the effects of Emodin and diphenyl ethylene glucoside on antioxidation of Radix Polygoni Multiflori at molecular lever.

目的：从分子水平研究何首乌中主要成分大黄素、二苯乙烯苷的抗氧化作用。

OBJECTIVE: To investigate the effect of stilbene glucoside on hypoxia-reoxygenation injury of human umbilical vein endothelial cells.

目的：观察二苯乙烯苷对人脐静脉血管内皮细胞缺氧/复氧损伤是否具有保护作用。

AIM To study the mechanisms of 2, 3, 4, 5-tetrahydroxystilbene-2-O-β-D glucoside for its antiatherosclerotic effect.

目的 探讨二苯乙烯苷抗动脉粥样硬化的可能机制。

Stilbene glucoside protects HUVECs against hypoxia-reoxygenation injury, which has superior therapeutical effect to that of prevention.

二苯乙烯苷对血管内皮细胞缺氧复氧损伤具有明显的保护作用，而且其治疗作用优于预防作用。

On the basis of this, the relationship between concentrations of stilbenes in the samples and the heartwood resistant ability was studied.

并在此基础上，研究木材中细胞次生代谢产物——二苯乙烯类化合物的含量与木材对真菌腐朽耐受性的相关性。

Resveratrol (3,5,4'- trihydroxystilbene) was first isolated from the roots of white hellebore Veratrum grandiflorum O.

白藜芦醇( 3，5，4'三羟基二苯乙烯)最早是于1940年从白藜芦的根茎中分离所得。

ResultsOnly five species of Pholidota genus were studied and 41 compounds were isolated and characterized including 9,10dihydrophenanthrenes, phenanthraquinone, bibenzyls, stilbenes, triterpenoids, phenyl propanoids, lignans, sterols and aliphatic compounds, and some plants and compounds exhibited analgesic, antioxidant, anticancer and NO production inhibitory activities.

结果目前石仙桃属植物研究所涉及的种类仅5种，从该属植物中分离出化学成分41种，包括9， 10二氢菲、菲醌、联苄、二苯乙烯、三萜、苯丙素、木脂素、甾体和脂肪族等结构类型。一些种类所含成分在镇痛、抗氧化、抗癌、抑制NO生成等方面显示了较好的活性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
