Rice Bran (Oryza sativa L. cv Cilliwung) is a by-product of the rice milling process, consisting of an outer layer of rice grains with the whole seed institute. Rice bran oil is a result of rice bran extraction. Rice bran oil contains antioxidant compounds, one of which is oryzanol, so this study aims to determine the levels of or-oryzanol in rice bran. The stages of the research included sample preparation, extraction using Microwave-Assisted Extraction (MAE), followed by Vacuum Liquid Column Chromatography (VLCC) was extracted using the MAE method produced 30 mL of black-brown rice bran oil extract. A total of 8 grams of rice bran extract was obtained at VLCC using eluent (n-hexane: ethyl acetate) with ratios 9:1, 7:3, and 1:1, respectively. Then the five factions obtained were characterized using HPLC, and GC/MS identified the mass of the γ-oryzanol compound.

Introduction: In our previous study, secondary metabolites of endophytic fungi isolated from gall rust sengon showed their bioactive activity against antibacterial and antioxidant, but only gave little effect to antifungal activity. Endophytic fungal culture extracted from gall rust of sengon (Falcataria moluccana Miq. Barneby and J. W. Grimes) has the ability on inhibiting Bacillus subtilis, Pseudomonas aeruginosa and Escherichia coli. To increase the production of bioactive compounds, this research was focused on isolates which produced the highest activity compounds, and sought the optimal fermentation conditions in the production of bioactive compounds. Methods: The fermentation process was carried out on PDB liquid media for 21 days, under shaker conditions, at room temperature, and sampling measurements were hold every 3 days. Bioassay were carried out against B. subtilis, P. aeruginosa, and E. coli. Results: The early stages fungal growth was adaptation stage, continued by 1-6th days of exponential growth period. Day 6-12th was stationary growth and day 15-21th were cell death periode. The highest secondary metabolite production was achieved at stationary periodes, that was occured at days 9-15th\ and high antibacterial activity was produced on days 9-12th. Conclusion: The best production secondary metabolite that has high activity was at day 9-12th.

Objective: The objective of this study was to investigate the antibacterial activity of coastal plants and marine sponges extracts against fish bacterial pathogens. Methods: Samples were extracted by maceration and the extracts were examined for their antibacterial activities against Streptococcus sp. BJ0509, Staphylococcus aureus ATCC 6538, Aeromonas hydrophila BA03 and Vibrio parahaemolyticus 29S by means of paper disc diffusion method. Active extracts were partitioned and purified by column chromatography. The purified substance was tested for Minimum Inhibitory Concentration (MIC) against seven bacterial fish pathogens namely Streptococcus sp., Vibrio parahaemolyticus, V. alginolyticus, V. harveyi, Photobacterium damselae, Aeromonas hydrophila and A. dhakensis. Results: The highest antibacterial activity against all bacteria used in the assay was demonstrated by OKA 6, a bark extract sample of a coastal plant, Diospyros maritima. It showed a diameter of inhibition zones against Streptococcus sp. BJ0509, S. aureus ATCC 6538, A. hydrophila BA03 and V. parahaemolyticus 29S of 19, 33, 18, and 18 mm, respectively. The column chromatography fraction of OKA 6 inhibited the growth of S. aureus ATCC 6538 with MIC of 3.125 μg/mL. The MIC of this fraction against seven bacterial fish pathogens ranged \< 0.098 to 3.125 μg/mL. The antibacterial activity of partially purified substance obtained from column chromatography fractionation of OKA 6 was higher than those of oxytetracycline and kanamycin. Conclusions: This result indicates that antibacterial activity of the partially purified substance is potentially higher than those of the commercial antibiotics tested. It further indicates that OKA 6 extract from D. maritima can serve as a promising resource for the development of therapeutic agents against bacterial infections in aquaculture.

Objective: To analyze the accumulation of potential photo-protective compound groups, include phenol, flavonoid, and tannin in the leaf tissues of Sonneratia caseolaris (L.) Engler. Methods: The research used Sonneratia caseolaris (L.) Engler leaves as materials. The total of compound groups and photo-protective ability level of each tissue was measured using spectrophotometry, while detection of compound group accumulations in the leaf tissue were observed using histochemical assay. Results: Epidermis extract contained the highest content of total phenolic compounds (phenol, flavonoid, and tannin), followed by those of mesophyll and whole leaf. Moreover, Sun Protection Factor (SPF) value of epidermis was also higher than those of mesophyll and whole leaf, considering that there were no significant difference of SPF value between mesophyll and whole leaf. Result of histochemical assay of S. caseolaris fresh leaf sections showed that phenol, flavonoid, and tannin were highly accumulated in the epidermis and some parts of mesophyll. Conclusion: Potential photo-protective compound groups of S. caseolaris leaves were accumulated in epidermis and mesophyll. However, epidermis showed the highest level of potential photo-protective compound groups than those of other tissues. Photo-protective ability of epidermis also showed higher value than those of mesophyll.
