1-Eicosane, A Hydrocarbon from Curvularia lunata an endophytic fungi isolated from bark tissue of Ficus religiosa

The structure is further confirmed by comparison of the spectrum obtained with the mass spectrum of Eicosane from the GC-MS database WILEY and NIST respectively. [...]the the endophytic fungi Curvularia Lunata serves as an alternative source for 1- Eicosane production which is used as a fuel in automobile industry. [...]analysis of the compound was done by Thin Layer Chromatography (TLC), Ultra Violet (UV), Fourier Transform- Raman (FT-R), Nuclear Magnetic Resonance (NMR) and GC-MASS.TLC analyses were carried out on Merck0.25-mm silica gel plates developed in the solvent systems of chloroform/ ethyl acetate (2:1, v/v) and it showed a mauve colored spot with the Rf value of 0.5 (Fig.2) which yielded 475 mg. The purified compound further subjected to FT-Raman analysis showed the existence of (sp3hybridized carbon) C-H stretching vibration indicates- certainly there is a CH2 or CH3 groups. Since there is characteristic peak at 2880.50 cm-1 (Fig.4). Volatile hydrocarbons from the endophyte Fusarium solani isolated from the bark of the plant Taxus buccata was active against human pathogenic microbes29. 1-Eicosane, a C20 alkane is a heavy fraction alkane having the chemical formula (CH3(CH2)18CH3), molecular weight 282,55 g/mol, melting point/freezing range 35-37°C to 37-40°C, initial boiling point and boiling range 220°C at 40 hPa and Flash point > 113,00°C.1-Eicosane is the hydrocarbon, used as a PCM (Phase change material based cooling) especially as a solid-liquid PCM's for periodic power dissipating devices30.
