植物甾醇

Study on the extraction technology of phytosterol from rice-bran by ultrasonic in this paper .

植物甾醇是植物中广泛存在的一类具有重要生物活性的物质。

The phytosterol extracted from plant fruits of our factory is natural pure green food, its specific index is as follows

本厂从植物果实中提取的植物甾醇是纯天然绿色食品，具体指标如下

Phytosterol is a kind of substance of physiological activity, which is directly extracted from plant through supercritical carbon dioxide extraction technology. Therefore, it does not contain any unidentified compositions such as organic solvents and metal ions, etc. It can be widely used in the industries of medicine, food and feed etc.

植物甾醇是一类具有生理活性的物质，采用超临界二氧化碳萃取技术直接由植物中提取而得，所以不含任何有机溶剂及金属离子等不明成分，能广泛应用于医药，食品，饲料等行业。

The hemisuccination process and kinetics ofβ-sitosterol and stigmasterol with succinic anhydride were studied, respectively.

为植物甾醇琥珀酸酯化反应过程和植物甾醇琥珀酸酯化产物的分离与精制过程的工业化提供理论指导和技术参数。

Therefore, it has great meaning to establish the analysis method of plant sterol in China, and determining the contents of plant sterols in plant foods commomly consumed in Chinese people so that we can evaluate the dietary intakes.

因此，建立植物甾醇的分析方法、测定食物中植物甾醇含量、估计居民摄入量有重要意义，可以为我国植物性食物的合理利用提供基础数据，也为科学指导居民膳食提供依据。

The hemisuccination process and kinetics ofβ-sitosterol and stigmasterol with succinic anhydride The reaction product ofβ-sitosterol and stigmasterol with succinic anhydride were characterized by elemental analysis,~1H NMR and ~(13)C NMR.

应用高效液相色谱对混合植物甾醇琥珀酸酯化产物中各组分的含量进行了分析测定。实验结果表明，各种植物甾醇琥珀酸单酯的分离效果较好，响应时间在10min左右，面积归一法能够快速准确地用于该过程的分析测试。

This paper reviewed the study situation of several forest chemical products associated with medical and health such as sterols,paclitaxel, betulinic acid and hinokitol.

综述了植物甾醇、紫杉醇、桦木酸、桧木醇等几种与医药保健品有关的林产化学品的研究开发现状。

Androstenedione and dehydroepiandrosterone as a new steroid material attracts people's attention because of the shortage of diosgenin resource and successful synthesis of AD by degradation of sterols. The followings were included in this thesis: 1. 24 new oxime-ether and oxime-ester compounds from AD were synthesized by cleavage of A-ring through NaIO_4/KMnO_4 oxidation, ring closure by amination, oximation with hydroxylaminechloride in C-17 position.

甾体药物的合成原料一般为薯蓣皂素、剑麻皂素、番麻皂素等，随着薯蓣资源日渐枯竭，使得甾体药物工业不得不寻求新的原料，而微生物降解胆固醇和植物甾醇合成雄烯二酮获得成功，使得AD成为新兴的甾体原料吸引了人们的注意。

In conclusion,plant sterols and stanols effectively reduce serum LDL cholesterol and cardiovascular risk.

总之，植物甾醇和植物甾醇酯能有效的降低血液中的LDL-Ch，以达到降低引发心血管疾病的风险的目的。

Plant sterols are extracts of certain plants that, when ingested, inhibit the absorption of cholesterol in the small intestine.

植物甾醇提取物是某些植物，当毒物，抑制吸收的胆固醇在小肠。

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。
