Identification and Comparative Studies of Different Volatile Fractions from Monochaetia kansensis by GCMS

Natural products from fungi are reported for various anticancer, antioxidant and other biological activities. So in search for novel bioactives from fungi isolated and identified from infected leaves of Rhododendron sp. Thus the isolated fungus was identified as Monochaetia kansensis, was extracted with variety of solvents of increasing polarity such as chloroform, Dichloromethane and ethylacetate for bioactive compounds extraction and identified by GCMS. In the chloroform extract, hexadecane (91.91%), E-15-Heptadecenal (3.98%) and phenol, 2, 4-bis (1,1dimethyl ethyl) (1.57%) were identified. Hexadecane is reported for activities such as antibacterial, antioxidant activities. In dichloromethane extract, compounds such as phenol, 2, 4-bis (1, 1dimethyl ethyl) (55.76%), 1hexadecene (20.77%), 2-pentene, 3-ethyl, 4, 4dimethyl (16.99%) and 1octadecenol (6.48%) was noted. In ethyl acetate fraction, 2tetradecene (22.00%), cyclodecane (19.39%), phenol, 2, 4-bis (1, 1dimethyl ethyl) (9.78%), E-15-Heptadecenal (8.70%) and 1-octadene (12.29%) were noted. In all the three extracts, the presence of phenol, 2, 4-bis (1,1dimethyl ethyl) was observed, where the compound is reported for antibacterial activity. E-15-Heptadecenal was present in both choloroform and ethylacetate extract at percentage of 3.98 and 8.70 respectively. In the chloroform and dichloromethane extracts, 1-hexadecene was observed at percentage of 0.93 and 20.77 respectively. Thus the basic study is focussed to study for the presence of volatile active compounds in the fungi isolated from the infected plant by GCMS.
