Infra Red and Gas Chromatogram / Mass Spectral Studies on Ethanolic Extract of Didemnum Psammathodes

C. Veerabahu, V. K. Meenakshi and K. F. Roselin

In the present study, the ethanolic extract of Didemnum psammathodes have been subjected to Infra red (IR) spectral study and Gas chromatogram/Mass spectral (GC-MS) analysis. Infra red spectral study indicates the presence of aromatic ring, carboxylic acid and moisture or hydroxyl compounds (O-H stretching). The GC-MS analysis revealed the presence of eight compounds. The nature of the compounds identified were steroids, plasticizers, triterpenes and ketones. Major compounds present in this extract are 2,6,10,14,18,22-Tetracosahexaene, 2,6,10,15,19,23-hexamethyl-, (all-E)- [Synonyms: All-trans-Squalene], Dibutyl phthalate, 1,2-Benzenedicarboxylic acid, diisooctyl ester. The resulting chemical compounds exhibit many biological activities such as anti-microbial, anti-fouling, anti-oxidant, anti-cancer, antiinflammatory, anti-arthritic, anti-asthmatic, diuretic, pesticide and chemo-preventive.
