The results showed that temperature rise would inhibit their esterification capacity, ethyl caproate-producing capability of raw zymin of 1# high-temperature monascus improved with the prolong of the esterification time when ethanol concentration was 4 %vol and caproic acid content was 4 mL, and when ethanol concentration and caproic acid content was within proper range, caproic acid content had more effects on the formation of ethyl caproate by raw zymin than ethanol concentration.

结果表明，温度相对升高对其酯化力的形成有一定的抑制作用；高温型红曲1#酯化菌株粗酶制剂的酯化力在乙醇浓度为4 %vol、己酸含量为4 mL时，产生己酸乙酯的能力随酯化时间的延长而增强；在适宜的乙醇浓度和己酸含量范围内，己酸含量对酯化酶粗酶制剂己酸乙酯生成影响比乙醇含量的影响大。

Now, Flavonoids and ginkgolides were mainly extracted from the leaves of Ginkgo biloba., but the leaves often contain high content of corious and cereous, and the effective constituent is very different under the various conditions. In addition, the constituent of ginkgolides is very low in the leaves, and thus the quality of extraction is difficult to reach the international standards.

目前人们主要从银杏叶中提取银杏黄酮和萜内酯，但由于银杏黄酮和银杏内酯的含量很低，尤其银杏叶中最主要的有效成分银杏内酯B主要存在于根中，在银杏叶中含量极低(＜0.1％)，且是在生长状态的叶中含量最高，采叶影响树的生长；又因银杏叶中主要的有效成分受多种因素的影响又有很大差别，银杏叶革质化、蜡质化程度高，使得国内银杏叶提取物的质量很难达到国际标准。

A novel type of amphiphilic tri-block copolymers with both pH and temperature sensitiveness: poly-poly (dimethylamino ethyl methacrylate)-poly (ε-caprolactone)(PEG-PDMAEMA-PCL) was synthesized via sequential oxyanionic polymerization of macro-molecular: PEG, with a hydroxyl at one end, and dimethylamino ethyl methacrylate andε-caprolactone, with the potassium naphthalene as the initiator.

The first synthetic route uses 1,2,4-trimethoxybenzene and chloroacetonitrile in forming 2,4,5-trimethoxy-a-chlor-acetophenone under the anhydrous condition, then the intermediate condensates with papaverine forming the core pyrro[2,l-a]isoquinoline, followed by formation and lactonization to form the lactone ring. The second synthetic route uses prepared aldehyde with prepared ethyl nitroacetate by Knoevenagel condensation to obtain 2-Nitro-3-(2,4,5-tris-methoxy-phenyl)-acrylic acid ethyl ester and 2-Nitro-3-(2,4,5-tris-benzyloxy -phenyl)-acrylic acid ethyl ester etal intermediates. The lamellarin skeleton could arise from condensation of the papaverine and these intermediates by Michael reaction, the ester group is provided for subsequent lactonization. The third synthetic route uses coumarin or indan-l,3-dione derivatives and papaverine to form lamellarin under basic conditions.

The aim of this study was to develop a novel amphiphilic functional block poly(ε-caprolactone) bearing ketone groups MPEG-b-P(OPD-co-CL. 2-oxepane-1, 5-dione was copolymerized with ε-caprolatone in which methoxy poly (MPEG, Mn=5 000) and stannous octoate were used as initiator and catalyst, respectively. The syntheses were conducted by bulk and solution polymerization. 1H NMR results showed that peak position and splitting of the polymers synthesized through solution polymerization were consistent with theoretical data, demonstrating the products were designed block copolymers. While in the bulk polymerization, polymer peak position was changed due to their high reaction temperature, suggesting their structural variation.
