[Oligoelements and lipids in pterocladia from the lebanese coast]

While pursuing our studies on marine algae growing on the Lebanese coast, our attention was drawn by an important type: ''Pterocladia''. Its presence was noted on the coast of Beirut, Manara. Careful analysis showed that it contained proteins and carbohydrates in adequate amounts, as well as twenty five types of oligoelements and some fatty acids such as palmitic, stearic, myristic and lauric acids. Among these various substances, Si [Silicium] and palmitic acid were present in large amounts, which led us to suggest that organic Si could be isolated and used in treating various diseases and conditions. As an example, it could be used in topical application for its analgesic effect. The remaining algae extract could be used as a supplement to infant's diet [milk] in order to contribute to development and growth of various organs that need fatty acids and other lipids

Trace elements and lipids in Padina Pavonica, in Lebanon

The present study is one of a number of studies that we conducted on the Lebanese coast [the coast of EI-Barbara] in order to determine the types of marine algae that grow there. We have already studied Fucus vesiculosus and Jania rubens. Padina Pavonica was the type we analyzed in this study. Using the Gas Chromatography [GC] method, we determined 9 types of fatty acids and 14 types of trace elements. Then, we compared our findings with the active ingredients found in Fucus vesiculosus and Jania rubens. We found that Padina pavonica contains 2 fatty acids that we did not find in any of previously studied algae: eicosanoic [C20:0] and cis 11-eicosaenoic acids [C20:1]

Trace elements and lipids in Jania Rubens, in Lebanon

The project of studying marine algae on the Lebanese coast was conducted, with the help of the National Council of Research, in order to define the most important types of marine algae. This is why we studied at first the Fucus vesiculosus [we have 2 projects in that domain] [1, 2]. Afterwards, we pursued the same study, choosing this time another type that we found very rich in active ingredients: Jania rubens. Indeed, after collecting samples from the coast of El- Barbara, we found, by means of Gas Chromatography [GC] seven types of fatty acids and, in another analyses, 14 types of trace elements. A comparaison between active ingredients contained in Fucus vesiculosus with those contained in Jania rubens, showed that the latter could play a more important role in medicine, pharmacy and nutrition
