Infra Red and Gas Chromatogram / Mass Spectral Studies on Ethanolic Extract of Didemnum PsammathodesAuthor(s): 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.
