Nghiên cứu hàm lượng lipit tổng, thành phần các lớp chất lipit của hai loài san hô mềm Sinularia brassica, Sinularia flexibilis và hai loài thủy tức (san hô lửa) Millepora dichotoma, Millepora platyphylla thu thập được ở vùng biển Nha Trang, Việt Nam cho thấy có sự khác biệt đáng kể. | Vietnam Journal of Marine Science and Technology Vol. 19 No. 1 2019 87 91 DOI https 1859-3097 19 1 13389 https jmst Study on total lipid content lipid class composition of some fire and soft corals collected in Nha Trang Vietnam Nguyen Ba Kien1 2 Trinh Thi Thu Huong3 Luu Van Huyen4 Nguyen Thanh Vinh5 Tran Duy Phong6 Dang Thi Minh Tuyet3 Nguyen Thi Nga3 Dang Thi Phuong Ly3 Pham Quoc Long3 1 Graduate University of Science and Technology VAST Vietnam 2 Vietnam Soils and Fertilizers Research Institute Hanoi Vietnam 3 Institute of Natural Products Chemistry VAST Vietnam 4 Hanoi University of Natural Resources and Environment Hanoi Vietnam 5 Hanoi University of Pharmacy Hanoi Vietnam 6 Fisheries Development and Consultancy Joint Stock Company Hanoi Vietnam E-mail trinhthuhuong2001@ Received 3 October 2017 Accepted 31 December 2017 2019 Vietnam Academy of Science and Technology VAST Abstract For the first time the total lipid content and lipid class composition of the Vietnamese soft corals Sinularia brassica Sinularia flexibilis and fire corals Millepora dichotoma Millepora platyphylla were investigated. The results indicated that the total lipid content of the investigated species was significantly different. Compositions of the lipid classes were analyzed using TLC and image analysis program Sorbfil TLC Videodensitometer DV and the results showed that phospholipids PL monoalkyldiacylglycerols MADAG and hydrocarbon wax HW were the main lipid classes of the total lipid in soft coral species. Meanwhile PL TG ST and HW were predominant in fire coral species. ST TG and FFA contents in soft and fire corals were at low level. DG was only present in the Sinularia flexibilis but not in other studied corals. Keywords Soft corals hard corals lipids lipid layers.
