内容記述 | Di(2-ethylhexyl) phthalate (DEHP) and unsaturated fatty acids (UFAs), as positive control, were isolated from Laminaria japonica (Makonbu) and Undaria pinnatifida (Wakame) to investigate a possibility of the isolated DEHP as a natural product by the analysis of natural abundance 14C contents. Wild L. japonica and cultured U. pinnatifida were freeze-dried and extracted with dichloromethane. DEHP and UFAs were isolated and purified by GC from the extracts. The 14C contents (pMC) of DEHP and UFAs from Laminaria japonica were 14.8 ± 0.1 and 103.7 ± 0.4, respectively, and from Undaria pinnatifida were 2.32 ± 0.04 and 96.9 ± 0.3, respectively. Therefore, DEHP isolated from L. japonica and U. pinnatifida was the industrial origin. | |||||
