Characteristics of Composition of Volatile Organic Compounds in Caulerpataxifolia

Caulerpataxifolia is an invasive alga that has caused serious environmental problem in global ocean. Differing from the other studies using HS-SPME/GC-MS method, in this study used a purge-trap method with GC-MS to analysis the components of volatile organic compounds (VOCs) in Caulerpataxifolia is used. According to the standard spectrum library, 65 volatile organic compounds were identified and their contents were semi-quantified by the peak area normalization method. The area percentage contents, furan and phenolic compounds with some toxicity were relatively high, which may have adverse effect on the growth of other algae. Halohydrocarbon, organosulfur and benzene compounds which have important effects on atmospheric environment were also detected in Caulerpataxifolia.
