Figure 5
Effect of leaves extracts derived from R. parviflora on different Lactobacillus strains. Various lactobacilli strains (108 CFU/ml) were cultured in presence or absence of various extracts/saquinavir (a commercially available HIV-1 protease inhibitor used as a reference control) at 100 μg/ml, for 24 h at 37°C and followed-up by viability assessment using MTT assay as described in Methods. Values are expressed as percent viability determined by dividing the absorbance of treated cells to untreated cells followed by multiplication with hundred. Data is represented as mean ± SE of three independent experiments performed in duplicates. Statistical significance of either the increase or decrease in viability of lactobacilli treated with either plant extracts or saquinavir as compared to untreated lactobacilli is shown by alphabets (ap < 0.05).
