化合物简介
Guaiazulene, also azulon or 1,4-dimethyl-7-isopropylazulene, is a dark blue crystalline hydrocarbon. A derivative of azulene, guaiazulene is a bicyclic sesquiterpene that is a constituent of some essential oils, mainly oil of guaiac and chamomile oil, which also serve as its commercial sources. Various soft corals also contain guaiazulene as a principal pigment. Its low melting point makes guaiazulene difficult to handle, in contrast to the crystalline nature of the parent azulene. The electronic structure (and colors) of guaiazulene and azulene are very similar.

生产方法及用途
生产方法
提取蓝樟油 ( 馏程220~300℃)通入氮气与钯 碳试剂,沸腾反应5h,滤出的油料中加入石油醚和80%磷酸。酸层用石油醚洗涤后,加入多量冰水,用石油醚萃取。有机相用2%氢氧化钠和水洗涤后,浓缩产物为愈创木奥粗品,得率以蓝樟油计为8%。 1.愈创木奥为CTFA认可的化妆品助剂,可以缓解其他物质对皮肤的刺激和过敏反应,为常见的外用抗过敏剂,有明显的抗炎功能,在防晒制品中用于预防或治疗阳光灼伤。可抗菌,口腔卫生用品中加入0.1%即可抑制微生物生长。愈创木也可用作化妆品色素.
