植物甾醇

By inhibiting the sterol biosynthesis of cell death in plants conduction with absorption in the role of ascomycetes and a half for the bacteria known to a wide range of diseases caused by a very good control effect.

通过抑制甾醇的生物合成而使菌体死亡，在植物体内具有内吸传导作用，对于子囊菌和半知菌引起的多种病害防效极佳。

The chemical constituents from Primulaceae plants are mainly flavonoids, terpenoids, sterols, organic acids, quinines, etc. These plants have effects of lowering serum uric acid level in mice, promoting bile secretion in rats, reducing bile pigment stones formation rate, immune regulation and so on.

报春花科植物中主要化学成分有黄酮类、萜类、甾醇类、有机酸类、醌类等；药理活性主要有降低小鼠的血清尿酸水平，促进大鼠胆汁分泌，减少胆色素结石的成石率，免疫调节功能等。

Results Six compounds were isolated and identified as:5α,8α-epidioxy-(22E,24R)-ergosta-6,22-dien-3β-ol,scopoletin,isofraxidin,p-hydroxy benzaldehyde,3,4,5-trimethoxy benzoic acid,protocatechuic acid ethyl ester...

结果得到6个化合物，分别鉴定为：5α，8α表二氧(22E，24R)麦角甾6，22二烯3β醇、东莨菪素、异秦皮啶、对羟基苯甲醛、3，4，5三甲氧基苯甲酸、原儿茶酸乙酯。结论化合物Ⅰ～Ⅵ均为首次从该属植物中分离得到。

Chinensis by the methods of column chromatography (normal and reversed phase silica gel, Sephadex LH-20), preparative TLC and HPLC. On the basis of spectroscopic methods including IR, ESI-MS, 1-D and 2-D NMR, forty eight of them were identified as seventeen flavonoids, seventeen tritepenoids, one cumarin, five steroids and some benzene derivative etc.

中药射干为射干植物的干燥根茎，从中共分离出53个化合物，通过红外、质谱及核磁共振等波谱方法鉴定了包括12个新化合物在内的48个，结构类型分别属于iridal型三萜及其新颖的二聚体、异黄酮、黄酮及黄酮醇、香豆素、甾体、芳香酸和脂肪酸及其甘油酯等。

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。
