Keywords: Aloe vera , Colletotrichum gloeosporioides , Leaf spot, Biochemical groups, Phenolics, Chlorophyll, Vitamin E


This study aimed to determine the alterations in major biochemical contents of Aloe vera infested by Colletotrichum gloeosporioides. Effects of fungal pathogen C. gloeosporioides on chlorophyll-a, chlorophyll-b, total chlorophyll, total soluble sugar, total phenols, total anthraquinones, total flavonoids, carotenoids and vitamin E were analyzed in artificially infested leaves of A. vera. While significant decrease in the contents of chlorophyll-a, chlorophyll-b, total chlorophyll, carotenoids and total soluble sugar was observed, an increased concentration of total phenolics, total anthraquinones, total flavonoid and vitamin E contents was recorded in infested leaves as compared to control. Being a medicinal plant, A. vera suffers a huge loss in its yield due to the attack of number of fungal pathogens. Moreover, changes in the concentration of its main biochemical groups were directly associated with the adverse effect of pathogens during the progression of infection on plant leaves. Therefore, control of the fungal diseases by applying appropriate management strategies is the important thrust to protect the plant of an enormous commercial value.
