“…The fruit extracts showed zone inhibition of 10.17mm on S. typhi but its action on other tested organisms were not apparent. Vivek et al [36] revealed that 1/10 of the original volume of cashew juice showed 26 -36 mm and 16 -17 mm zone of inhibition on S. aureus and S. mutans respectively. The difference could be as a result of the differences in the concentration of the fruit extract (juice) and the synergistic reactions of the various phytochemicals [36].…”

Extracts of the leaf, stem bark and fruit of cashew plants were investigated to determine their phytochemical, antioxidant and antimicrobial properties. Cashew leaves, stem barks and fruits of the Brazilian Jumbo variety were processed, extracted and analyzed for their phytochemical, antioxidant and antimicrobial activities. The results showed that the phytochemical contents varied significantly between the sample extracts. Carotenoids content of cashew extracts are 88.86, 125.93 and 100.33 mg/g for the leaf, bark and fruit respectively. The stem bark extract showed significantly highest tannin content (2.01 mg/g) compared to the cashew fruit extract (1.56 mg/g) and cashew leaf extract (1.19 mg/g). Total phenolic content of the cashew plant parts varied significantly from 103.92 -983 .23 mg/g sample of the extract with the leaf extract having significantly lowest value while the fruit had the highest value. Cashew fruit extract exhibited significantly highest percentage DPPH scavenging activity at all concentrations. There was a positive correlation between the total phenolic content and antioxidant activities of cashew extracts suggesting that the phenolic content may directly influence the antioxidant activities. Extracts of cashew leaves and stem barks exhibited appreciable inhibition on all human pathogens screened compared to the fruit extract which was only active against salmonella typhi. Cashew extracts could therefore be used as a potential source of ingredients in the development of nutraceuticals and functional foods for the control, management and treatment of health disorders.

“…In our study, the leaf extract showed a dose dependent inhibitory activity against oral isolates of S. mutans. It has been experimentally shown that plants and their products exhibit marked inhibitory activity against cariogenic flora (Fani and Kohanteb, 2007;Jose and Beegum, 2007;Ferrazzano et al, 2009;Almeida et al, 2012;Vivek et al, 2013).…”

Article Information The present study was performed to estimate elementals and to determine bioactivities namely anticariogenic, antioxidant, pancreatic lipase inhibitory and cytotoxic activity of Chrysophyllum roxburghii leaves. Elemental analysis revealed that calcium and manganese were present in high concentration among principal and trace elements respectively. Preliminary phytochemical analysis revealed the presence of tannins, alkaloids and terpenoids in the extract. Total phenolic content was found to be 179.05mg Gallic acid equivalents/g of extract. The methanol extract caused a dose dependent inhibition of Streptomyces mutans isolates. All the isolates tested were found to be sensitive to extract. In DPPH assay, t he extract exhibited marked dose dependent scavenging activity against DPPH free radical with an IC50 value of 3.54μg/ml. In Ferric reducing assay, the absorbance of the reaction mixture was found to increase with the concentration of extract which is suggestive of reducing power. The activity of chicken pancreatic lipase was affected by the extract and the effect was concentration dependent. Higher inhibition of enzyme (>50%) was observed at extract concentration 50mg/ml. In cytotoxic study, the lethality was found to be directly proportional to extract concentration. Highest mortality (>80%) of shrimps was observed at extract concentration 1000µg/ml. LC50 of extract was 83.04µg/ml. The bioactivities of the extract could be attributed to the presence of secondary metabolites in the plant material. The plant material could be used as a source of important elements required for the body. In suitable form, the plant could be used in the prevention and treatment of dental caries, oxidative damage, obesity and cancer.

“…The isolates of S. mutans and S. aureus were inoculated into sterile Brain heart infusion broth (HiMedia, Mumbai) and Nutrient broth (HiMedia, Mumbai) tubes respectively. The tubes were incubated at 37 o C for 24 hours (Vivek et al, 2013).…”

“…Using sterile cork borer, wells of 6mm diameter were punched in the plates and 100μl of lichen extracts (10 and 20mg/ml of 25% dimethyl sulfoxide [DMSO; HiMedia, Mumbai]), reference antibiotic (Chloramphenicol, 1mg/ml of sterile water) and DMSO (25%, in sterile water) were transferred into labeled wells. The plates were incubated at 37 o C for 24 hours in upright position and zones of inhibition were measured (Vivek et al, 2013).…”

Article InformationThe present study was conducted to evaluate the antibacterial efficacy of methanol extract of three species of macrolichen Parmotrema (Parmeliaceae) viz., P.tinctorum (Nyl.) Hale, P. grayanum (Hue.) Hale and P. praesorediosum (Nyl.) Hale from Western Ghats of Karnataka against clinical isolates of burn and dental caries. Identification of lichens was done by morphological, anatomical and color tests. The powdered lichen materials were extracted using methanol in soxhlet apparatus. Inhibitory potential of lichen extracts was evaluated against two isolates of Staphyloccus aureus (Sa-01 and Sa-02 from burn subjects) and two isolates of Streptococcus mutans (Sm-01 and Sm-02 from dental caries) by agar well diffusion assay. Lichen extracts were found inhibitory against all clinical isolates and the inhibitory activity was dose dependent. Among S. aureus and S. mutans isolates, Sa-02 and Sm-02 were inhibited to higher extent respectively by lichen extracts. Extract of P. praesorediosum inhibited S. aureus isolates to higher extent. Extracts of P. praesorediosum and P. tinctorum inhibited S. mutans isolates to higher extent. The lichens of this study were found promising sources for development of agents active against clinical isolates. The observed activity of extracts could be ascribed to the presence of secondary metabolites.
