This study was performed to evaluate the antimicrobial activity of aerial parts of chloroform extract of Cassia auriculata L. The chloroform extract of C. auriculata were shown to possess an antimicrobial activity against two gram positive and two gram negative human pathogenic bacteria and fungi, viz. Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and fungus cultures Candida albicans and Aspergillus niger by using disc diffusion method. The extract showed antibacterial activity at all concentrations selected, but only the extract with the concentration of 300µg/ml showed maximum antibacterial activity against all the organisms except Pseudomonas aeruginosa which are comparable with the standard control, amikacin. The anti fungal activity of chloroform extract of C. auriculata revealed significant effect against Candida albicans and Aspergillus niger with the net inhibition zone of 14 and 14 mm, respectively at 300µg/ml concentration, which is almost comparable with standard control, ketokonazole used as an antifungal agent. The phytochemical analysis showed the presence of alkaloids, carbohydrates, fixed oils, fats, tannins, gum & mucilage, flavonoids, saponins, terpenoids, lignin and sterols. It is concluded that the antimicrobial activity showed by the plant was due to the presence of these phytochemicals. Further studies are highly needed for future drug development.

This article contains data on in vitro cytotoxicity activity of chloro-form, methanolic and water extracts of leaf and heartwood of Cae-salpinia sappan L. a medicinal plant against Breast cancer (MCF-7) and Lung cancer (A-549) cells. This data shows that Brazilin A, a natural bioactive compound in heartwood of Caesalpinia sappan L.induced cell death in breast cancer (MCF-7) cells. The therapeutic property was further proved by docking the Brazilin A molecule against BCL-2 protein (an apoptotic inhibitor) using auto dock tools.

Objective: To elucidate cytotoxic activity of fractions from chloroform and methanol extracts of D. bulbifera organs on T47D breast cancer cells. Method: The vegetative organs of D. bulbifera were extracted gradually using chloroform and methanol. Cytotoxicity tested on T47D cells using MTT Assay. The most toxic extract was fractioned by vacuum liquid chromatography (VLC) followed by thin layer chromatography (TLC). The extract and fractions potential were tested on the Vero cells using the same method as cancer cells. The most toxic fraction was analyzed using TLC followed by the application of various spray reagents for the identification of active compound. Results: The chloroform extract of the D. bulbifera leaves was the highest cytotoxic on T47D cells (IC 50 115.63±86.01 µg/mL). Moreover, the cytotoxicity test on the combined fractions of leaves chloroform extract showed that fraction 5 (F5) and fraction 6 (F6) were the most toxic fractions compared to those of other fractions. The IC 50 of both fractions were 14.55±8.62 and 7.12±4.43 µg/mL respectively. However, Its were very weak compared to those of cancer medicine (Doxorubicin) with the IC 50 was 0.04±0.02 µg/mL. Potential fractions were not toxic against Vero cells with IS>10. The active compounds in those fractions were alkaloid and terpenoid. Conclusion: Chloroform extract of the D. bulbifera leaves had the highest cytotoxic effect on T47D cells. Potential fractions were not toxic against Vero cells. The active compounds in those fractions were alkaloid and terpenoid.

"Emergence of new strains of Escherichia coli with the ability of resistance to a wide range of antibiotics necessitates the efforts to search alternatives for better treatments to deal with these infections. Chamomile is one of the most widely used herbs in the world. In this study we investigated the potential therapeutic effects of chamomile chloroform extract on E. coli intraperitoneal (IP) infection of BALB/c mice. Female BALB/c with an average weight of 20 to 25 g, were divided into 8 groups. Lethal dose of the E. coli for mice was injected IP in test groups and treated with 5.25, 10.5 and 21 mg/mL of chamomile chloroform extract. The combined effect of the extract (50 µg/mg) with amikacin and amikacin alone were also examined. The highest number of survived mice at the dose of 10.5 mg/mL of extract and the highest death rate with 5.25 mg/mL of extract was observed. In amikacin group all infected animals were survived. Mortality rate in chamomile extract combination with amikacin is almost the same as amikacin alone. The significant lowest mortality rate was observed in the some group which had been treated with a combination of extract and amikacin. The result of this study does not recommend in-vivo using of chloroform extracts of chamomile for E.coli infection via IP administration. In vivo chloroform extracts of chamomile, it seems not to have a strong antibacterial effect on E. coli IP infection of BALB/c mice."

The plant Pomegranate (Punica granatum Linn.) selected for this study is native to the region of Eurasia. The objective of this study was to evaluate the antitrypanosomal potential of the plant against Trypanosoma brucei brucei (T.b. brucei) and Trypanosoma evansi (T. evansi). Similarly, the parasites used for this study have two entirely different modes of transmission that is Cyclical Transmission (T.b. brucei) and Mechanical Transmission (T. evansi). The chloroform extract of Punica granatum (P. granatum) was analysed in vitro for trypanocidal activity against T.b. brucei and T. evansi at concentrations of 100 mg/mL, 50 mg/mL, 25 mg/mL, 12.5 mg/mL and 6.25 mg/mL. The chloroform extracts of P. granatum had trypanocidal activity against T. evansi and was inactive against T.b. brucei. These findings suggest that the mode of transmission may have an effect on the parasite-drug reaction and the possible use of the chloroform extract of P. granatum in the management of trypanosomiasis due to T. evansi which may require further elucidation.
