Abstract

The crude polar extract of mangosteen fruit pericarp not only has a moderate antioxidant activity of (55±4 μg/mL) but also has high cytotoxicity (16±0.5 μg/mL). The high cytotoxicity presumably is caused by the presence of complex cytotoxic compounds from the mangosteen pericarp. To obtain a non-toxic extract preparation with high antioxidant activity, polar crude 50% ethanol extracts of mangosteen pericarp were partially purified using reverse-phase column chromatography with Silica C18 as the stationary phase and acetonitrile-water gradient elution. Six of the ten fractions collected had high antioxidant activities, with IC50 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging antioxidant levels <50 μg/mL. Three fractions (fractions 3, 5, and 7) with the highest antioxidant activities of (16.4 ± 0.6 µg/mL), (17.8 ± 2 µg/mL) and (17.4 ± 1.8 µg/mL) respectively, were chosen for further cytotoxicity, phenolic content and High-Performance Liquid Chromatography (HPLC) analysis. The cytotoxic tests were conducted with the Brine Shrimp Lethality Assay. Fraction 3 had low cytotoxicity (LC50 485 ± 96 µg/mL) and fraction 5 was non-toxic (LC50 ≥ 1000 µg/mL), while fraction 7 still had high cytotoxicity (LC50 2.8 ± 0.8 µg/mL). The chromatogram profiles of HPLC showed that fractions 3 and 5 contained more polar compounds than the compounds present in fraction 7. It can be concluded that the reverse phase method succeeded in the isolation of a non-toxic polar fraction, that is, fraction 5, with a significantly higher (p<0.05) antioxidant activity than in the original crude polar extracts. This fraction had a high total phenolic content of 43.3 ± 0.3 g GAE per 100 g extract.

Abstract

An antibiotic-resistant and multidrug-resistant (MDR) issue open the role of researchers to continue to search for natural potential as a source of new antimicrobials. One of the potential fungi isolates that can produce antimicrobial active compounds from Indonesian tropical peat soils is Penicillium sp. LBKURCC34. In this study, the production of antimicrobial compounds from local isolates was carried out by batch fermentation method in liquid media with the addition of biotic elicitors to increase the extraction activity and yield. This study aims to optimize the results based on the time the elicitor is added. Staphylococcus aureus was used as a biotic elicitor, which was added on days 2, 3, and 4 in the production of antibiotics by fermentation incubation of 6-14 days. The antibiotic production media was extracted with ethyl acetate and evaporated. The antimicrobial test was carried out by the disk diffusion method against pathogenic bacteria Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Staphylococcus epidermidis using three crude extract contents (19; 38; and 57 µg/disc). Amoxicillin® was used as a positive control (10 µL/disc). The results showed that the addition of S. aureus biotic elicitor extended the log phase growth of the fungus Penicillium sp. LBKURCC34. The optimum condition of production was obtained by adding initiator treatment on the 3rd day for 14 days incubation with the highest yield and could inhibit the growth of all pathogenic microbes.
