The volatile oil was obtained from the seed of Fibraurea recite pierre by steam distillation. Twenty-six chemical constituents were identified by CC-MS. The relative content of docosane was the highest.

采用水蒸气蒸馏法提取大黄藤种子挥发油，结果表明：所得提取物经CC-MS检测出26种化合物，其中相对含量最高的化合物是二十二烷。

Here we introduced oxadiazole moiety to theside-chain of Ph-PPV to enhance the electron transport properties. The luminescenceefficiency and luminescence brightness (1.33cd/A, 9400 cd/m~2) of the Ph-PPV withside oxadiazole moiety are much higher than non-oxadiazole Ph-PPV (0.70 cd/A,2300 cd/m~2), and these polymers emitted green light which unaffected by theintroduction of oxadiazole moiety. Anthracene has a rigidity and planar structure which shows high photoluminescenceand thermo-stability.

结果表明，以十烷氧基作为间隔基使噁二唑单元键接在苯基取代PPV的侧链，所得材料制备的电致发光器件的效率和亮度(1.33cd／A，9400 cd／m~2)明显高于不含噁二唑单元的苯基取代PPV(0.70 cd／A，2300 cd／m~2)，噁二唑单元的引入并不影响材料的发光光色，膜状态下的荧光发射光谱和电致发光光谱均呈绿光发射。

结果：从皱皮木瓜的乙酸乙酯萃取部位分离鉴定了9种化合物，分别为绿原酸甲酯，5-O-咖啡酰基－奎宁酸丁酯，奎宁酸丁酯，5-羟甲基－2-糠醛，三十烷酸，-表儿茶素，7，8-二羟基香豆素，3，4-二羟基苯甲酸乙酯，原儿茶酸。

In order to get the information of interaction between metal complex and DNA and select metal complexes which can cleave DNA effectively, twenty seven transition metal complexes containing O/N coordinate atoms have been synthesized in this thesis. We report the synthesis, crystal structure and properties of the complexes. One of the complexes is the first μ〓-oxalato tetranuclear Cu complex, in which there is ferromagnetic interaction between the copper atoms bridged by oxalate ions. Two trinuclear copper complexes containing partial cubane Cu〓O〓 cores have been synthesized and discussed the magnetic properties.
