The study aimed to establish the quantitative analysis method with HPLL on total saponin of Panax notoginseng and research the stability of the total saponin.

［目的］建立三七总皂甙的液相色谱定量分析方法，研究三七总皂甙的稳定性。

With the total saponin of P. notoginseng as the investigated index, the HPLC method was used to discuss the effect of different pH value and different temperature on the stability of the total saponins of P. notoginseizg.

方法］以三七总皂甙为考察指标，采用高效液相色语法，探讨不同pH值、温度对三七总皂甙稳定性的影响。

Results The mutation incidence of LKG was 22.96%, while the mean incidence of GPG was 7.59%(The incidences of C20-OH group, glucoside group and aglucon group were 5.32%, 6.25% and 11.00% respectively). When treated with DMBA for 4 to 8 weeks, the mutation incidence of LKG ranged from 11.10% to 40.00%, while GPG ranged from 0 to 10.70%.

结果 白斑癌变模型组突变率达22.96%，绞股蓝处理组平均为7.59%；绞股蓝各组抗突变率效佳依次为C20-OH组、总甙组、甙元组，其突变率分别为5.32%、6.25%、11.00%；DMBA诱导癌变4～8周时白斑模型组突变率为11.10%～40.00%，绞股蓝处理组为0～10.70%。

Methods: The fluorescence char acteristics of astragaloside anisic reaction product were used to determine astragaloside in serum.

利用茴香酸在硫酸介质中与黄芪甲甙反应产生强烈荧光的特性，测定血清中的黄芪甲甙。

Chapter 5: The fluorescence quenching reactions of barbaloin with serum albumin in solution were studied. The quenching mechanism of serum albumin by barbaloin was interpreted using the Stern-Volmer mechanism. The binding constant K values and the number of binding sites were calculated, respectively.

第五章：首次研究了芦荟甙与血清蛋白在溶液中的相互作用，利用Stern-Volmer方程解释了芦荟甙对血清蛋白的荧光淬灭，并测定了不同温度下的结合常数及结合位点数。

The common building block of them was synthesized by firstly glycosylation of an appropriately protected glucose with diosgenin, then introduction of a rhamnosyl residue to the 2-OH at Glu, finally freeing the 4-OH at Glu by selectively benzoylation of 6-OH.

我们先将适当保护的葡萄糖接在薯蓣甙元上，然后选择性地保护葡萄糖的 3 位羟基，在 2 位上引入一个鼠李糖，接下来选择性地保护葡萄糖的 6 位羟基，得到了上面三个皂甙的共同合成子。

In order to exploit the resources ofCrocus sativus and crocin further, molecular biological research of saffron wasstudied in the thesis.

为了研究西红花药用成分西红花甙的资源，更好地利用西红花甙，本论文对西红花进行了分子生物学方面的研究：对西红花酸合成酶(7，8-二加氧酶)基因的克隆，并将其在大肠杆菌中表达，纯化诱导蛋白，制备相应的特异性抗体。

Callus derived from petiole explants of Panax japomcus var. major produced three cyanidin glycosides as major anthocyanin pigments in darkness. Anthocyanin synthesis was remarkably stimulated by 2,4-dichlorophenoloxyacetic acid in combination with kinetin in MS medium. The pigment content of the callus reached up to 34. 14 mg/g fw.

从珠子参(panax japonicus var.major)叶柄诱导的愈伤组织在暗培养条件下主要形成3种花色甙色素，且均以矢车菊素为甙元。2，4-二氯苯氧乙酸和激动素的组合能明显地促进色素的合成，色素含量可达34.14mg/g fw。
