Research Article Bioactive potential of sea urchin Temnopleurus toreumaticus from Devanampattinam, Southeast coast of India

The present investigation elucidates the bioactive potential of aqueous extract of sea urchin Temnopleurus toreumaticus. In this investigation biochemical, heamolytic, cytotoxic and FT-IR analysis were followed by standard methods. In biochemical analysis, proteins content 2.70 mgmL-1, total carbohydrates content 2.15 mgmL-1 and total lipids content 0.03 mgmL-1 were showed in aqueous extract of sea urchin. In heamolytic assay, the goat and chicken erythrocytes showed the maximum 64 Hemolytic Unit (HU) and human blood group “A ” shows 32 HU, blood group “B ” shows 64 HU, blood group “AB ” shows 32 HU and blood group “O ” shows 128 HU. In cytotoxic study, aqueous extract of sea urchin showed LC50 value 0.12±0.09 mgmL-1 concentration was showed 50 % mortality. In antimicrobial assay, maximum zone inhibition 12.26 ± 0.6 mm showed by K. oxytoca and 3.33 ± 0.9 mm showed by Mucor sp. against chloroform extract of sea urchin T. toreumaticus. Thin layer chromatogram showed the spots of Rf values of 0.38, 0.85 cm. The FT-IR study shows the presence of functional groups such as chloroalkanes, bromoalkanes, iodoalkanes, alcohols groups, acids or aromatic ethers, methyl alkyl groups, 1 ° amines groups and ammonium ions. These results indicate that, sea urchin has remarkable hemolytic and cytotoxic activities
