Abstract

Buah Merah (Pandanus conoideus Lamk.) has been extensively used to treat various diseases includingcancer. There are many varieties of buah merah and there was no scientifi c study comparing cytotoxicity ofdifferent varieties. The objective of this study was to investigate the cytotoxicity of three varieties of buah merahknown as Barugum, Maler and Yanggiru on breast cancer cell line (T47D). All samples were collected fromPapua, Indonesia. Each sample was extracted consecutively using three solvents chloroform, methanol andwater resulted to nine crude extracts. The cytotoxic activities were determined using MTT assay. The crudeextract showed the lowest IC50 was selected for further bioassay-guided fractionation. Fractionation was doneusing vacuum liquid chromatography coupled with preparative TLC to fi nd the active compounds. Severaldetection reagents were applied to TLC for identifi cation of the class of the potent compounds. The resultshowed that the potent extracts was obtained from Barugum methanol extract followed by Maler chloroformextract with IC50 value of 132.83 μg/ml and 139.72 μg/ml, respectively. All Yanggiru extracts did not showactivity. The bioassay-guided fractionation of Barugum and Maler extracts showed that the most potent fractioneluted by a mixture of hexane:ethyl acetate (75:25), was in Maler variety with IC50 value of 25,7 μg/ml, fourtimes higher than the most potent fraction of Barugum with IC50 value of 104,61 μg/ml. TLC analysis of themost potent fraction showed that the active compounds was class of terpene. Result of this study supportedthe utilization of buah merah Maler variety for breast cancer treatment.

Abstract

Endophytic microbes are potential sources of antibiotics. Some numbers of endophytic bacteria were isolated from plants in Ujung Kulon, Kaliurang, Meru Betiri and Baluran National Park, Bogor Botanical Garden, and Nusakambangan forest, Indonesia. Previous studies have been conducted to examine and obtain endophytic bacteria isolates from the selected plants, which resulted in three selected isolates, namely OOH-1, STG-1, and CMB-2. This research was conducted to determine the molecular identity of OOH-1 and STG-1 isolates, as well as to identify antibiotic compounds produced by STG-1 isolate. Molecular identifcation of selected isolates was based on 16S rRNA gene analysis and amplifed using primers 27F and 1492R. A phylogeny tree was then constructed by comparing the resulting sequences with data from Gene Bank using the BLAST-N program. The identifcation showed that STG-1 isolate had a 99% similarity with Pseudomonas brenneri strain SFML 97-391, and OOH-1 isolate had a 99% similarity with Enterobacter xiangfangensis. Identifcation of antibiotic compounds was done by purifcation and separation of the compounds. Antibiotic activity was also examined based on Lethal Concentration (LC50) on Fusarium oxysporum with a LC50 of 0.01–0.02% against Fusarium oxysporum.

Abstract

Avocado Persea Americana Mill. is a commercially important crop and studies have shown that the pulp may have benefits to cardiovascular health, dermatological health and possibly anti-cancer activity. Avocado seeds have several medicinalproperties such as anti-hyperglycemic, antimicrobial, antioxidant and anti-inflammation. This study aim to evaluate the effect of avocado seed extract on viability and apoptosis of breast cancer cell line MCF-7. The anticancer effect was evaluated by cytotoxic test using MTT assay and the effect on apoptosis and cell cycle was examined by flow cytometry method. The cytotoxic test showed that chloroform extract had strong cytotoxic activity against MCF-7 cell lines with IC50 value of 94.87 μg mL-1. Furthermore, the chloroform extract was partitioned with methanol and yield of soluble methanol fraction (FLM) and non soluble methanol fraction (FTLM). The cytotoxic activity of the methanol soluble fraction (FLM) and non soluble methanol fraction (FTLM) against MCF-7 cell lines was increased with IC50 of 34.52 and 66.03 μg mL-1, respectively. Flow cytometry analysis using annexin-V and propidium iodide staining revealed that methanol soluble fraction could induce apoptosis and modulating the cell cycle arrest in MCF-7 cell. This research indicated that avocado seed has a potency to induce apoptosis and as anti-proliferative to MCF-7 cells lines.
