A Chemical Study of the Chilean Flora

该奖项支持由宾夕法尼亚州立大学的Maurice Shamma、蓬塔阿雷纳斯的Magallane大学的Victor Fajardo和智利圣地亚哥大学的Alejandro Urzua对智利植物区系的化学研究进行的合作研究。他们将研究从几个属植物叶表面存在的粘性化合物中获得的某些类固醇。这些化合物可能作为对草食性害虫的防御，并将被研究可能的抗癌潜力。双方的设施是互补的；美国科学家将在解释复杂的核磁共振谱方面提供专业知识，智利人将通过使用他们的色谱设备和UV和IR光谱仪来帮助阐明化学结构。他们也有植物提取的设施。这两位科学家将在宾夕法尼亚州立大学花费时间将天然产物从植物中分离出来，并获得光谱数据。该项目是实现发展中国家科学计划目标的一个很好的例子。

This award supports cooperative research on chemical studies of Chilean flora to be conducted by Maurice Shamma of Penn State University, Victor Fajardo of the University of Magallanes in Punta Arenas and Alejandro Urzua of the University of Santiago, Chile. They will study certain steroids obtained from the sticky compounds present on the surface of the leaves of plants from several genera. These compounds may act as defense against herbivorous pests and will be investigated for possible anticancer potential. The facilities of both sides are complementary; the U.S. scientist will contribute expertise in the interpretation of complex NMR spectra and the Chileans will help elucidate the chemical structures through the use of their chromatographic equipment and UV and IR spectrometers. They also have facilities for plant extraction. These two scientists will spend time at Penn State to isolate the natural products from plants and obtain spectral data. This project is a good example of the fulfillment of the goals of the Science in Developing Countries program.
