Study on total lipid content, lipid class composition of some fire and soft corals collected in Nha Trang, Vietnam

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, 10.91–16.02%), monoalkyldiacylglycerols (MADAG, 20.69-39.92%) and hydrocarbon wax (HW, 29.83-37.17%) were the main lipid classes of the total lipid in soft coral species. Meanwhile, PL (24.11-33.23%), TG (14.27–34.92%), ST (10.10–14.50%) and HW (12.08–19.95%) 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.

Carbon And Nitrogen Content

We determined seasonal cycles of lipid content, lipid class composition, and carbon and nitrogen content of seven taxa of zooplankton that were collected from the Beaufort Sea shelf, Canadian Arctic, over a 10-month period (September 2003 – August 2004). All taxa except the chaetognath Parasagitta elegans had substantial lipids stores (>50%), either seasonally (Oikopleura spp.) or throughout the year (Calanus hyperboreus, Calanus glacialis, Paraeuchaeta glacialis, Metridia longa, and Eukrohnia hamata). Wax esters were the dominant lipid class in the chaetognath Eukrohnia hamata and in all copepods, including the carnivore Paraeuchaeta glacialis. Seasonal trends in lipid content and composition varied among taxa; some taxa had little variation from winter through summer (e.g., Parasagitta elegans), other taxa showed little variation until summer (e.g., Calanus glacialis), and others showed increasing or decreasing trends during winter and spring (e.g., Calanus hyperboreus). Specifically, total lipid content of Calanus hyperboreus decreased from January through May at a rate of ∼450 μg·month−1·individual−1 in adult females and ∼100 μg·month−1·individual−1 in juvenile copepodite IV, representing a 75%–85% loss in lipid.

Five soft coral samples belonging to the same specimen Sinularia brassica were collected in the coastal area of Ha Long Quang Ninh, Nhat Le beach, Quang Binh, Hon Vang - Thanh Hoa and Nha Trang areas (2014–2016), these samples were examined and analyzed by total lipid content, content and composition of lipid and fatty acids. Highest total lipid content was found in the sample SHM 09 collected in Nha Trang bay (1.11%), and the lowest total lipid content was in HL-SHM 07 collected in Ha Long, Quang Ninh (0.68%).The lipid composition of samples contained basic classes such as polar lipids, sterols, free fatty acids, triacylglycerols, monoankyldiacylglycerols, hydrocarbons and waxes. In studied soft corals, there are the appearance of all fatty acids from C12 to C24. There are differences in composition and content of lipids and fatty acids in samples collected in different locations: Samples collected at Nha Trang bay contain more polyunsaturated fatty acids than the other samples collected in Ha Long, Thanh Hoa, Quang Binh. Another two samples, collected in Hon Vang (Thanh Hoa) have similar composition and content of lipid classes, the composition and content of fatty acids in total lipids. The obtained results also show the significant impact of habitat and time of acquisition on the studied subject.

High Polarity

Samples from cured burley and flue-cured tobacco were examined for total lipid content and for lipid composition of fractionated lipid classes. Cured burley tobacco contained 6–8% lipids compared with 14–15% in cured flue-cured tobacco. Neutral lipids constituted 70–80% of burley lipids but only half the flue-cured lipids; the latter had 75% more neutral lipids than the former. Flue-cured tobacco contained considerably more (5–10 times) medium- to high-polarity lipids than burley. Stalk position had only a minor effect on the lipid content of both tobacco types.
