Clam Anadara inaequivalvis (A. inaequivalvis) is a mollusc having Indo-Pacific origin and currently living also in several areas of the Mediterranean Sea where it probably arrived due to maritime transport, attached to the boats’ hulls or carried in the ballast water1. Despite its nutritional value, similar to that of the more appreciated clam Chamelea gallina, (C. gallina), it has not cornered the market as food, thus fishermen must pick it out from the other molluscs2. However its chemical composition, makes A. inaequivalvis interesting as a possible source of nutrients and nutraceuticals. In our study, we applied several methods for extracting lipids, in order to evaluate the actual fatty acids composition of this mollusc. The extract has been further investigated for determining the lipid composition and particularly the phospholipid fraction. A picture of the total lipid composition has been obtained through SPE purification3 of the extract and TLC analysis. The first results suggest that phosphatidylserine (PS), phosphatidylinositol (PI) and phosphatidylethanolamine (PE) are mainly present in the extract. A comparison with the clam C. gallina is also under consideration; methods and preliminary results will be presented.

Abstract
Clam Anadara inaequivalvis (A. inaequivalvis) is a mollusc having Indo-Pacific origin and currently living also in several areas of the Mediterranean Sea where it probably arrived due to maritime transport, attached to the boats’ hulls or carried in the ballast water1. Despite its nutritional value, similar to that of the more appreciated clam Chamelea gallina, (C. gallina), it has not cornered the market as food, thus fishermen must pick it out from the other molluscs2. However its chemical composition, makes A. inaequivalvis interesting as a possible source of nutrients and nutraceuticals. In our study, we applied several methods for extracting lipids, in order to evaluate the actual fatty acids composition of this mollusc. The extract has been further investigated for determining the lipid composition and particularly the phospholipid fraction. A picture of the total lipid composition has been obtained through SPE purification3 of the extract and TLC analysis. The first results suggest that phosphatidylserine (PS), phosphatidylinositol (PI) and phosphatidylethanolamine (PE) are mainly present in the extract. A comparison with the clam C. gallina is also under consideration; methods and preliminary results will be presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
