1、用下劃線標(biāo)注說(shuō)明下列各題中每一字段的含義。 （1）期刊出版物的文摘標(biāo)頭： 129：248995z Calculation of the Hydrodynamic Contribution to Peak Asymmetry in High-Performance Liquid Chromatography Using the Eequilibrium-Dispersive Model. Stanley, Brett J.; Savag, Theresa L; Geraghty, Jennifer J. (Department of Chemistry Califonia State University, San Bernrdino, CA, 92407-2397, USA). Anal. Chem.. 1998,70(8), 1610-1617 (Eng), Americal Chemical Society. （2）期刊論文文摘全文示例： 116：105900k A new approach for the synthesis of the chiral sex pheromoneof peach leafminer moth.. Chen, Zikang; Zhu, Jun; Cheng, Ying (Dep. Chem., Beijing Norm. Univ., Beijing, Peop. Rep. China 100875). YoujiHuaxue 1991, 11(5), 530-3(Ch).The enantiomeric 14-methyl-1-octadecenes were prepd. by cross coupling reation between the Grignard reagent of 12-chloro-2-methylhexane from corresponding (R)-or (S)-2-methylhexanoic acid under the catalysis of Li2CuCl4. The overall yied of the each enantiomer is about 30% from the racemic 2-methylhexanoic acid and the optical purity is approx.100%. The (S)-enantiomer showed strong bioactivity as the sex pheromone of peach leafminer moth in field tests. |
