Gas chromatography–mass spectrometry (GC-MS) analysis of antimicrobial compounds produced by mahua oil cake against the stem rot pathogen- Sclerotium rolfsii

The antifungal property containing oil cakes play a significant role in reducing plant disease wide range of soil-borne pathogens. A destructive pathogen, Sclerotium rolfsii is infecting vast crops worldwide. In-vitro efficacy five different viz. mahua cake, neem pungam coconut cake and castor extracts was tested against the stem rot pathogen groundnut. Among cakes, extract produced minimum mycelial growth 1.57and1.29 cm at 5%, 10% concentrations, respectively showed maximum percent inhibition 83.33and 86.66% respectively. Bioactive compounds were analyzed through GC-MS. From result GC-MS, high retention time peak area percentage observed with major important bioactive like n-Hexadecanoic acid (24.968) (12.22), Hexadecanoic acid, ethyl ester (23.655) (2.9), 9,12-Octadecadienoic (Z, Z)-(28.659)(35.61), 9-Octadecenoic (E)-(28.786) (13.15), Octadecanoic (29.137) (33.59) a1-Octyn-3-ol (3.023) (0.04).The identified GC-MS from found to be exhibiting activity S. rolfsii.
