Dictyotaceae是次生代谢物的丰富来源，尤其是萜类。这些天然产物因其对人类的生物活性和在自然界中的生态作用而被研究。目前的工作突出了Dictyotaceae萜烯的多样性，强调了它们的生物活性和来源的生物地理学。倍半萜类化合物存在于Padina、Dictyopteris和Taonia中。虽然Dictyopteris和Padina在所有海洋中都有分布，但桃属的分布较为有限。已报道的混合来源的二萜类化合物存在于罗非目、桃属和柱花科植物中。裸子植物是典型的热带暖温带属植物。二萜类化合物的骨架为spatane和Seco-spatanes，分别见于Spatoglossum、Stoechosperum和Rugulopteryx。赤舌藻广泛分布于整个热带海洋世界。已知的Stechosperum发生在印度洋，Rugulopteryx主要分布在亚洲和澳大利亚的太平洋海岸。Dictyota属含有作为主要代谢物的二萜类化合物，存在于所有海洋中，甚至可以到达南北半球的寒冷温带地区。Dictyotaceae中的萜类化合物具有生物活性，如抑制食草动物和抗真菌、细胞毒性、抗菌、抗炎、杀虫和抗病毒活性。
Dictyotaceae are a rich source of secondary metabolites, especially terpenes. These natural products have been studied for their bioactivity for human and for their ecological role in nature. The present work highlights de diversity of the Dictyotaceae terpenes, emphasizing their bioactivities and the biogeography of their sources. The sesquiterpenes are found in Padina, Dictyopteris and Taonia. Although Dictyopteris and Padina can be found in all oceans, Taonia has a more restricted distribution. Diterpenes of mixed origin have been reported in Lobophora, Taonia and Stypopodium. Stypopodium is a typically tropical and warm temperate genus. Diterpenes with the spatane and seco-spatanes skeletons are known from Spatoglossum, Stoechospermum and Rugulopteryx. Spatoglossum is distributed over all the tropical marine world. Stoechospermum is known to occur in the Indian Ocean and Rugulopteryx is distributed mainly in Asia and on the Pacific Coast of Australia. The genus Dictyota contains diterpenes as the major metabolite and are present in all oceans, reaching even the cold temperate regions of northern and southern hemispheres. The terpenoids from Dictyotaceae exhibit bioactivities such as inhibition of herbivores and antifungal, cytotoxic, antibiotic, anti-inflammatory, insecticidal and antiviral activities.
