Gorgonians respond to insult (damage and disease) by producing sclerites containing a purple pigment as opposed to the normal white sclerites. Raman microscopy is used to study the purple areas of three species of diseased coral, Gorgonia ventalina, Pseudoplexaura porosa, and Eunicea laciniata obtained from Puerto Rico. These spectra were compared to Gorgonia ventalina samples previously reported that were obtained from San Salvador, Bahamas. Spectra from two samples of G. ventalina that had been infected by different agents, Aspergillus sydowii and a slime mold, were also obtained. The results indicate that the purple compounds (polyenes) generated by the coral in response to infection are similar regardless of region from which the coral were harvested, of species of coral, and of the infective agent. A discussion of the Raman spectra of G. ventalina and the other coral species is presented.
柳珊瑚受到损伤（病害和疾病）时会产生含紫色色素的骨针，而不是正常的白色骨针。拉曼显微镜用于研究从波多黎各获得的三种患病珊瑚，即 Gorgonia ventalina、Pseudoplexaura porosa 和 Eunicea laciniata 的紫色区域。将这些光谱与先前从巴哈马的圣萨尔瓦多获得的 Gorgonia ventalina 样本进行了比较。还获得了两个感染不同病原体（黄曲霉和粘菌）的 G. ventalina 样本的光谱。结果表明，珊瑚对感染产生的紫色化合物（多烯）无论珊瑚的采集地、珊瑚种类或感染源如何，都是相似的。本文介绍了 G. ventalina 和其他珊瑚物种的拉曼光谱讨论。
