At the initial isolation to the extract from ethyl acetate, tow kinds of crystal a and b with higher purity were found, and the primary components were 98.45%. Quinic acid and 69.34% L-Proline, 5-oxo-, methyl ester.

在乙酸乙酯部分进行初次分离时，还得到了两种纯度较高的晶体a和b，经GC-MS分析可知其主要成份分别为98.45%奎宁酸和69.34%的5-脯氨酸甲酯。

The main organic acid was citric acid, followed by malic acid. Citric acid and tartaric acid levels increased during storage. Malic acid and quinic acid increased from stage one to stage two. Shikimic acid level increased from stage one to stage three, then decreased slightly. Acetic acid changed unremarkably. Succinic acid changed not significantly from stage one to stage two, then increased and it was the highest in the stage three. The level in stage four and stage five was lower than the level in stage three.

五九香梨果实中的主要有机酸是苹果酸和柠檬酸，整个贮藏期间，柠檬酸和酒石酸含量处于上升趋势，苹果酸和奎宁酸含量在第一、二月贮藏期间增加，而后开始下降；莽草酸含量在贮藏期第一到第三阶段上升，而后略下降；琥珀酸含量在第一到第二阶段变化不明显，接着有上升的趋势，在第三阶段含量达到最高，第四和第五阶段略低于第三阶段；乙酸含量变化不明显。

QN 〓PHAL,〓PHAL and 〓PHAL were quaternized by refluxing with benzyl bromide to give ligands 8, 9 and 10 respectively. 2. The chiral ligands were applied to the AD reaction of olefins with NMO as co-oxidant and PEG (400 MW) or PF〓 as reaction media.

以奎宁和奎尼定为原料分别与1，4-二氯-2，3-二氮杂萘反应制备〓PHAL和〓PHAL，然后通过〓PHAL、〓PHAL及〓PHAL与苄基溴的季铵化反应制备单季铵盐手性配体8、9和10。

A chiral phase transfer catalyst, N-benzyl quinine bromide, was synthesized from natural chiral compound. And 2,5-bimethyl-4-(3-nitrobenzene)-1,4-bihydrogenation pyridine-3--4-methyl formate (viz. nitrendipine) was synthesized by this chiral phase transfer catalysis, and characterized by elemental analysis, infrared spectrum,1H nuclear magnetic resornace, and X-ray single-crystal diffraction.Key words: ammonium; chiral phase transfer catalyser; crystal structure

通过对天然手性物质进行修饰合成手性相转移催化剂N-苄基溴化奎宁，并对目标分子2，5-二甲基-4-(3-硝基苯)-1，4-二氢吡啶-3-甲酸乙酯-5-甲酸甲酯进行不对称催化合成，并通过红外光谱和核磁共振氢谱对化合物进行了表征，用X射线单晶衍射法测定了该化合物的晶体结构。
