目的考察不同产地知母中总皂苷、菝葜皂苷元的含量。

The sugar chains are usually trisaccharide or tetrasaccharide, and the aglycones are classified into three groups, i.e., solanidane, spirosolane, and other steroidal derivatives.

糖苷生物碱是主要分布于茄科和百合科植物中的糖苷类次级代谢产物，糖链通常由3或4个单糖组成，苷元通常为三类甾体生物碱：茄次碱烷、螺旋甾碱烷和其他甾体衍生物。

Results When cellulase and pectinase compound,amlyse and diastatic enzyme were added in order in the method of stepwise biocatalysis,98% diosgenin from plants was extracted.IR spectrum of the product was in accordance with that of reference substance and the purity of it is more than 95% according to its HPLC chromatogram.

结果利用阶梯生物催化法，当纤维素酶和果胶酶复合酶制剂、淀粉酶以及糖化酶按顺序依次加入时，能够将植物中98%的薯蓣皂苷元提取出来，其产品的红外谱图与对照品谱图相吻合，经HPLC谱测定薯蓣皂苷元质量分数95%以上。

By the quantitative analysis of flavonoids from the extract under acid hydrolysis condition, it is demonstrated that the level of isoquercitrin degrades along with the content of hydrochloric acid elevating and the level of kaempferol is reverse. Those reveal that there exist flavonoid conjugates whose aglycone is kaempferol in the leaves.

对青钱柳酸水解液中成分的测定表明，随着酸浓度的提高，异槲皮苷的含量下降，槲皮素的含量上升，山奈酚的含量也随酸浓度上升而增高，表明青钱柳中尚有以山奈酚为苷元的黄酮苷存在。

From molecular structure of chemistry,picric in stevioside,sweetness,the relation between sweetness,aglycone join position and join glucosyl quantity were discussed in the paper.

本文从分子化学结构的角度出发，论述分析了甜菊糖苷甜中带苦涩后味的根本原因，甜度、甜味与苷元的C连接部位和连接葡糖基数的关系；对于现今改进甜菊糖苷的苦涩味的酶化方法，作了深入的比较、论证，并指出新的科学技术方法。

Result: Daidzein was remarkedly effecti ve in preventing ventricular fibrillation induced by chloroform in mice and arrh ythmia induced by aconitine in rats.

结果 ：大豆苷元(3.0，5.0mg·kg-1)对氯仿诱发的小鼠室颤有明显的预防作用，大豆苷元(0.8，1.0mg·kg-1)对乌头碱诱发的大鼠心律失常有明显的治疗效果。

Daidzine were hydrolyzed to genistein and daidzein, which can improve the healthy function of products.

发酵15天的成品豆豉中，95.3％的黄豆苷和83.4％的染料木苷转化为苷元，有利于提高产品的生理功能。

Icariin, the main constituent of Epimedium sagittatum Maxim, and its metabolite icariside Ⅱ showed similar activity in cell proliferation. The total flavonoids from Viscum coloratum Nakai could stimulate cell proliferation and significantly promote cellular ALP activity. Daidzein and its derivatives exhibited no significant activity in cell proliferation.

结果发现：中药淫羊藿中的主要成分淫羊藿苷及其大鼠体内主要代谢物淫羊藿次苷Ⅱ具有类似的作用，可显著促进成骨样细胞的增殖；中药槲寄生总黄酮对成骨样细胞的增殖有一定的促进作用，并可显著提高细胞内ALP活性；大豆苷元及其衍生物对UMR106细胞的增殖作用不明显。
