The isolation of microbial agents less susceptible to regular antibiotics and the rising trend in the recovery rates of resistant bacteria highlights the need for newer alternative principles. Triphala has been used in traditional medicine practice against certain diseases such as jaundice, fever, cough, eye diseases etc. In the present study phytochemical (phenolic, flavonoid and carotenoid) and antibacterial activities of aqueous and ethanol extracts of Triphala and its individual components (Terminalia chebula, Terminalia belerica and Emblica officinalis) were tested against certain bacterial isolates (Pseudomonas aeruginosa, Klebsiella pneumoniae, Shigella sonnei, S. flexneri, Staphylococcus aureus, Vibrio cholerae, Salmonella paratyphi-B, Escherichia coli, Enterococcus faecalis, Salmonella typhi) obtained from HIV infected patients using Kirby-Bauer's disk diffusion and minimum inhibitory concentration (MIC) methods. T. chebula was found to possess high phytochemical content followed by T. belerica and E. officinalis in both aqueous and ethanol extracts. Further, most of the bacterial isolates were inhibited by the ethanol and aqueous extracts of T. chebula followed by T. belerica and E. officinalis by both disk diffusion and MIC methods. The present study revealed that both individual and combined aqueous and ethanol extracts of Triphala have antibacterial activity against the bacterial isolates tested.

“…It could be concluded that the virus infected leaves have been attributed two causes-stimulation of chlorophylase which degrades chlorophyll into chlorophyllide and phytol and inhibition of chloroplast development which leads to the development of colour deviations like mosaic, yellowing, chlorosis, etc. The reduction of total chlorophyll was 60% in case of soyabean infected by Soya bean yellow mosaic virus (Narayanasamy and Palaniswami 1973). Multiplication of virus particles in the infected plant cells alters biochemical compounds of cells such as chlorophyll, β-carotene, organic carbon, nucleic acids, etc.…”

Alteration of cellular components and host physiology due to five biotypes of Cucumber mosaic virus (CMV) were investigated to know the effects on ultimate growth and yield of chilli. Severe reduction of cellular components like chlorophyll-a (59.31%), chlorophyll-b (68.40%), total chlorophyll (63.20%) and β-carotene (51.14%) were observed in plant infected by mosaic and stunting (MoS) as compared to healthy plant. The ratio of RNA to DNA was increased in the infected leaves. The reduction of photosynthesis rate was found 6.32 to 17.10% in CMV infected plants as compared to healthy plants. Stomatal conductance and inter cellular CO 2 was found lower in CMV infected plats. Considerable yield reduction (28.80 to 78.11%.) was found infected with five symptomatic isolate of CMV. The present findings indicate that multiplication of virus particles in the infected cells alter the biochemical compounds of cells that disrupt the physiological process which affect the growth and yield of chilli.
