Rahman AS, Purwoko T, Nugraheni ER. 2011. The influence of ethanol extracts concentration of mengkudu fruit (Morinda citrifolia) and storage time toward beef quality. Biofarmasi 9: 26-32. The high protein content of beef makes it easy to get a contamination caused by an activity of bacteria. The use of formalin as a preservative substance especially for beef can make a damage to health, so it is required to find preservative substances as alternative to substitute formalin. Mengkudu (Morinda citrifolia L.) has antibacteria compounds to the decompose bacteria of beef, so mengkudu fruit can be one of natural preservative substance alternatives, especially for beef. The purposes of this research were to determine the influence of ethanol extracts concentration of mengkudu fruit and a storage-time effect toward bacteria amount, and to determine the concentration that had a same activity with formalin to combate the replication of bacteria. This research used two-way completely randomized design. The samples were fresh meat beef that be submerged in mengkudu extract with concentrations of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100% and formalin 1% as a comparator. After that, the beef was storaged in a room temperature during 16 hours, and every 4 hours it was tested for water content, pH value, beef temperature and a total plate count (TPC) test with a dilution method, and then the number of bacteria colonies with the limit of the bacteria amount of the beef to consume might not be more than 1x104 CFU/gram. The data were analyzed by ANOVA. If there was a significance, it would be continued by a DMRT test with an error rate 5%. The research results showed that all extracts concentration of mengkudu fruit and storage-time gave a significant effect (p<0.05) toward bacteria amount. The concentration of 100% had the same activity with formalin to combate the replication of bacteria among 16 hours storage time.

Background Literatures revealed that 1,4-pentadien-3-one and triazine derivatives exhibited a wide variety of biological activities. In order to develop highly bioactive molecules, in this study, a series of novel 1,4-pentadien-3-one derivatives containing triazine moieties were synthesized and their antibacterial and antiviral activities were investigated. Methods A series of novel 1,4-pentadien-3-one derivatives containing triazine moieties were synthesized and characterized in detail via 1H NMR, 13C NMR and HRMS spectra. The antibacterial activities against Xanthomonas axonopodispv. citri (Xac), Xanthomonas oryzaepv. oryzae (Xoo) and Ralstonia solanacearum (R.s) were evaluated at 100 and 50 µg/mL using a turbidimeter and N. tabacun L. leaves under the same age as that of test subjects. The curative, protective and inactivation activities against tobacco mosaic virus (TMV) at a concentration of 500 µg/mL were evaluated via the half-leaf blight spot method. Results The bioassay results showed that some of the target compounds exhibited fine antibacterial activities against Xac and R.s. Particularly, half maximal effective concentration (EC50) values of some target compounds against R.s are visibly better than that of the positive control bismerthiazol (BT). Notably, compound 4a showed excellent inactivation activity against TMV with a EC50 value of 12.5 µg/mL, which was superior to that ofningnanmycin (NNM,13.5 µg/mL). Besides, molecular docking studies for 4awith tobacco mosaic virus coat protein (TMV-CP) showed that the compound was embedded well in the pocket between the two subunits of TMV-CP. These findings indicate that 1,4-pentadien-3-one derivatives containing triazine moieties may be potential antiviral and antibacterial agents.

Studies have shown that extract of the pericarp of mangosteen contained mostly of xanthones exhibit many biological activities, especially as an antitumor. This study aimed to investigate the cytotoxic activity and selectivity of Mangosteen Peel Extract (MPE) and α-mangostin against two leukemia cell lines (HL-60 and K-562) and the normal lymphocyte cells from two different donors. The cytotoxic activity was performed using 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxyme-thoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay. Imatinib and Isotretinoin were used as a positive control to the K-562 and HL-60 cells, respectively. The MPE and α-mangostin revealed higher mortality toward leukemia cell lines rather than toward lymphocyte cells, with more than 80% of HL-60 and K-562 cells died at 6.25 and 25 μg/ml, respectively. MPE was more toxic and selective against K-562 with IC50 of 2.79 μg/ml and SI of 8.27, while α-mangostin was more toxic and selective against HL-60 with IC50 of 1.12 μg/ml and SI of 22.34. MPE and α-mangostin showed potent sensitivity and selectivity to leukemia cells, hence these are considered as promising sources for future leukemia treatment.
