Assessment of Antifungal Activity of Some Himalayan foliose Lichens Against Plant Pathogenic Fungi

引用

American Journal of Plant Sciences 2011年第6期2卷 841-846页

作者： Priti Tiwari Himanshu Rai Dalip Kumar Upreti Suman Trivedi Preeti Shukla 不详

In vitro antifungal activity of the acetone, methanol and chloroform extracts of four lichen species viz, Bulbothirx setschwanensis, Everniastrum nepalense, Heterodermia diademata, Parmelaria thomsonii were investigated against seven plant pathogenic fungi (Aspergillus flavus, A. fumigatus, Alternaria alternata, Fusarium oxysporum, F. solani, F. roseum and Penicillium citrinum) with reference to commercially available synthetic antifungal drug Ketoconazole (positive control). Lichen secondary metabolites were extracted using Soxhlet extractor and were further recovered through gentle evaporation of solvents in rotatory evaporator. Antifungal activity was analysed employing BauerKirby disc diffusion assay. Acetone and methanol extracts of lichenized fungi were found more effective against tested plant pathogenic fungi. Principal component analysis concluded that though, Ketoconazole was effective against four of the tested plant pathogenic fungi, acetone and methanol extracts of lichens were comparatively more effective against some broad spectrum plant pathogenic fungi (Fusarium oxysporum, F. solani, F. roseum).

Lichen exploration of West Kameng district and Tawang district of Arunachal Pradesh state,India located in the Eastern Himalayas reveal seventy nine lichens represented primarily by foliose(73%),a few fruticose(15%),dimorphic(8%),leprose(2%)and crustose(1%)*** these,seventeen species,one fruticose,sixteen foliose growth forms,belonging to 12 genera and 5 families are recorded as new additions to the lichen flora of Arunachal Pradesh *** lichens were sampled at an elevation ranging from 1618 meter to 4509 *** diagnostic features of new additions to macrolichens of Arunachal Pradesh based on the phytogeographic affinities and distribution of species is briefly described.
