UV 254nm, 366nm and anisaldehyde as a chromogenic agent were used for detecting compounds of these strains. Results indicate that the metabolites of these strains were the most abundant when these strains were fermented in No.1 and No.4 media, and only few in No.2 and No.3. Metabolites of each strain were different in different media.

同时，通过分析在遗传优化过程中分子参数出现的频度，还得到了可能对活性影响较大的几个重要分子参数，它们分别是水／辛醇分配系数(ALogP98)、指示因子以及电性拓扑态指数。对该类抑制剂的设计和改造提供了指导。

Results Bulbus alkaloids easily formed molecular ions(superscript + in MS and dimerized easily in alcohol solution, which did not dimerize in acidity solution. Collision induced dissociation made these alkaloids easily lose a molecule of H2O. The MS spectra of the extracts of five Bulbu Fritillartae species indicated that the major molecular ions were similar to each other, but different varieties showed very different relative abundances of these molecular ions.

结果 在正离子一级质谱中，贝母生物碱易形成带一个正电荷的准分子离子，并且在中性醇溶液中，贝母生物碱易形成二聚体，在酸性介质中则无此现象；二级碰撞诱导解离易使贝母生物碱脱去一分子水；5种贝母对照药材的总生物碱提取液的一级电喷雾质谱图显示，主要分子离子峰基本相同，但因品种不同相对丰度差异较大。

The extracts of water and alcohol were separated by ion exchange resin. The eluates of neutral solution were the most effective against hydroxyl radicals and the highest rate of inhibiting hydroxyl radicals was 81%. The eluates of basic solution were also effective, the inhibit rate of which was 60%.

将发酵灵芝粉的水和醇提取物上离子交换树脂柱，依次用酸性、中性、碱性淋洗液洗脱分组，发现中性洗脱部分对羟基自由基抑制作用最强，抑制率最高可达81％；碱性洗脱部分亦具有抑制羟基自由基的效果；酸性洗脱部分抑制羟基自由基的作用不强，且占很少比例。

In order to accomplish this change, our research have made several important break-through by revising new formulation especially in (1) catalyst mix,(2) adjustment of water content,(3) addition of chain extenders and crosslinkers, and(4) utilization of long-chained polyols. By doing so, the general performances of our new non-yellowing foam products are comparable to those of the traditional TDI based products. In certain mechanical properties in areas such as tensile strength, split tear strength, and elongation our measured values of 1.89 kg/cm2, 1.47 kg/cm, and 355 % respectively have out-performed the old materials.
