Abstract

BACKGROUND: Brucea javanica extract has been reported to have anti-proliferative and cell death induction activities. B. javanica extract was reported to induce apoptosis through caspase cascade. Most of investigated B. javanica extracts were derived from seeds and fruits, or commercially available oil emulsion. Therefore we conducted a study on B. javanica leaf extract (BJLE) in oral cancer cells.METHODS: B. javanica leaves were collected, identified, minced, dried, extracted with distilled ethanol at room temperature for 24 hours, filtered and evaporated. Resulted BJLE was stored at 4°C. Human oral squamous cell carcinoma (HSC)-2 cells were fasted for 12 hours and treated with BJLE in various concentrations for 24 hours. Cells were then quantified with 3-(4,5-dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium bromide (MTT) assay, demonstrated with 4',6'-diamidino-2-phenylindole (DAPI) staining. To find out mitochondrial membrane permeability (MMP), mitochondrial membrane potential (ΔΨM) was analyzed.RESULTS: BJLE reduced percentage of viable HSC-2 cells in a concentration dependent manner. BJLE induced apoptosis in HSC-2 cells. With treatment of 50 μg/ml BJLE, fragmented nuclei were seen. ΔΨM of HSC-2 cells treated with 50 μg/ml BJLE were shifted to the left, meaning that BJLE induced reduction of ΔΨM and attenuation of MMP.CONCLUSION: Our results suggested that BJLE could induce apoptosis by attenuating MMP.KEYWORDS: Brucea javanica, leaf, apoptosis, HSC-2, MTT, DAPI, mitochondria, permeability

Abstract

BACKGROUND: Indonesia's tropical forest is home to around 80% of the world's medicinal plants. One of these is Zingiber purpureum, which have traditionally been used to treat joint discomfort, the common cold, and jaundice. The rhizomes of this plant have been suggested to possess antibacterial action in the treatment of infections. In this study, Z. purpureum was screened for antibacterial activity against 13 bacteria (Gram-positive and Gram-negative).METHODS: Z. purpureum rhizomes were obtained and the distillated extracts were made to generate essential oil. The minimum inhibitory concentration (MIC) and Kirby Bauer disk diffusion methods were used to determine the antibacterial activity.RESULTS: All bacteria activity were inhibited by the essential oil of Z. purpureum at concentrations ranging from 2.5 vol% to 10 vol%. However, several bacterias (Escherichia coli, Pseudomonas aeruginosa, and Enterobacter cloacae) were inhibited at the lowest concentration (0.63 vol %), with the inhibition zones ranging from 6.7 mm to 8.0 mm. Meanwhile, the widest inhibition zone (13.3 mm) was reported on E. cloacae at 10 vol% concentration.CONCLUSION: A 10 vol% Z. purpureum rhizome extract inhibits Gram-positive and Gram-negative bacteria, particularly those that are resistant to a variety of antibiotics.KEYWORDS: Zingiber purpureum, antibacterial agents, susceptibility test, infection
