We attached for the first time -NOBIN to Frechet-type dendron units. The syntheses of 16 kinds of dendrimer-based NOBIN Schiff-base ligands were achieved in a straightforward manner by simple condensation of -NOBIN with the corresponding salicylicaldehyde derivatives, of which 12 belong to the dendritic Schiff-base ligands and 4 belong to the non-dendritic Schiff-base ligands.
通过手性拆分获得了光学纯化合物NOBIN，首次将NOBIN手性单元连接到树枝状大分子中去，设计合成了四个系列16种新的NOBIN衍生的希夫碱三齿手性配体，其中4种为非树枝状手性希夫碱配体，12种为树枝状手性希夫碱配体。

The constituents of bulb of F. puqiensis were studied. Five steroid alkaloids were isolated. The plane structure and stereoscopic configuration of 4 compounds were elucidated. They are named as puqienine A (FP-33), puqienine B (FP-3), N-demethyl-puqietinone (〓 FP-34) and puqietinone (〓, FP-9). Puqienine A and N-demethyl-puqietinone are new compounds. Puqienine B is as same as FPQ-3 elucidated by Prof.

Methods: DECB was dealed with heat , acid , alkali , roasting , organic solvent extracting , microorganism zymolysis , then the method of microrespiromete was used to detect/measure the respiratory activity respectively.
目的：研究小牛血清去蛋白提取物（deproteinated extract of calf blood，DECB）中生物活性物质的物理化学性质；方法：分别将小牛血清去蛋白提取物进行加热、加酸、加碱、烘烤、有机溶剂萃取、接种微生物发酵等方法处理，然后分别用微量呼吸检压法检测呼吸活性，结果：采用加热、加碱、加酸，接种微生物发酵的方法进行处理，DECB刺激呼吸活性的能力没有明显改变，而采用烘烤的方法处理，结果DECB的活性完全消失；用有机溶剂萃取DECB，可明显降低DECB刺激呼吸活性的能力，而有机相中含有了刺激呼吸活性物质。

The ethanol extract was dissolved with HCl, the acidic extract was basified to pH9-10 with NH_3-water and extracted with CHCl_3 to give total alkaloids. five alkaloids were isolated with column chromatography and preparative thin-layer chromatography, and three of them were identified as dehydrocorydaline、 corynoline and dihydrosanguinarine on the basis of spectral analysis MS,~1H-NMR,~(13C-NMR and physicochemical properties. All of them were found for the first time from this plant.

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.
第一条路线首先从1，2，4-三甲氧基苯出发与卤乙腈作用合成卤代芳酮中间体，然后与罂粟碱反应合成开链片螺素，最后经乙酰化、去保护、成内酯环得到片螺素；第二条路线由制备的芳醛和制备的硝基乙酸乙酯经缩合得到2-硝基-3-芳基丙烯酸乙酯，然后由该中间体与罂粟碱反应，在完成关环的同时也引入酯基，最后去保护、成内酯环得到片螺素；第三条路线是由香豆素或茚二酮出发，经溴代后的中间体与罂粟碱反应，得到片螺素的基本框架。
