GC-MS Analysis of The Extract of Alternaria Perpunculata Fungus, Isolated from Diseased Weed Species of Paddy Fields; Alternanthera Sessilis.

Dondapudi spandana, P.K. Ratna Kumar


Alternanthera sessilis is the most predominant diseased weed of Devarapalli Mandal West Godavari District, Andhra Pradesh, India. Alternaria perpunculata is the causal organisms for the infestation of the A.sessilis leaves. The objective of the present study was to investigate the compounds present in the fungi Alternaria perpunculata fungi isolated from Alternanthera sessilis diseased leaves through Gas Chromatography-mass spectrometry (GCMS) . Based on the peak area, retention time molecular weight, molecular formula, chemical structure s and its properties they were identified. The study revealed that it showed the presence of fifteen compounds. The major compounds are 4-Hexyl-1-(7-methoxycarbonylheptyl)bicyclo[4.4.0]deca-2,5,7-triene(26.8%) Diethyl Phthalate(17%) and oleic acid. They can be used as plant metabolites, antioxidants, plasticizer etc.
