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.

该奖项支持宾夕法尼亚州立大学的莫里斯·沙玛（Maurice Shamma），潘塔阿雷纳斯（Punta Arenas）的马加兰语大学的维克多·法贾多（Victor Fajardo）和智利圣地亚哥大学的亚历杭德罗·乌尔津（Alejandro Urzua）进行的智利植物学合作研究。 他们将研究从几个属植物叶子表面上存在的粘性化合物获得的某些类固醇。 这些化合物可能是针对草食害虫的防御，并将进行调查，以提高可能的抗癌潜力。 双方的设施都是互补的。美国科学家将在解释复杂的NMR光谱方面提供专业知识，智利人将通过使用色谱设备以及UV和IR光谱仪来帮助阐明化学结构。 他们还设有植物提取的设施。 这两位科学家将花时间在宾夕法尼亚州分离植物的天然产品并获得光谱数据。 该项目是实现发展中国家科学目标的一个很好的例子。
