Isolation of the biotransformation product artemisinine from endophitic bacteria is a new alternative for the production of the multidrugresistant antimalaria compounds. The bacteria strain, AT 12, has been proved particularly potential as an artemisinin source.This working was carried out to isolate and to identify the biotransformation product artemisinin as an antimalarial active compound from endophitic bacteria strains of Artemisia annua. The IR spectrum exhibited the characteristic bands for Î´-lactone (1750-1735 cm-1, 1250-1111 cm-1) and endoperoxide function (~1115 cm-1, 890-830 cm-1). As a result, the GC-MS gave a positively identification for the majority of GC peaks. The mass spectrum of the peak (Rt 27.94 min) has a molecular ion of artemisinin with one hydrogen loss at m/z 281, representing (M+ - 1).Keywords: Artemisia spp. Artemisia annua, Endophytic, Artemisinine, sesquiterpene

Microorganisms activity and oxidation process can contribute to food spoilage occurrence. Natural source that have antimicrobial activity and antioxidant are potential as a natural preservative. The aims of this study are to investigate the endophytic fungi from turmeric plant which have antibacterial toward histamine-producing bacteria and antioxidant activity. Antibacterial activity of histamine-producing bacteria was done by paper disc diffusion, whereas the antioxidant activity was performed by free radical scavenging method. In the paper disc diffusion method were obtained 3 isolates which have the highest diameter of inhibition at concentration of 20.000 ppm: from root (15 mm), flower (14 mm) andÂ rhizome (13 mm). Also at the antioxidant assay, the lowest IC50 values were isolates from root (39,52 ppm), flower (157,93 ppm) and rhizome (96 ppm). Endophytic fungi from root, flower and rhizome had antimicrobial and antioxidant activity thus they could potentially used as a natural food preservative.Keywords: antibacterial, antioxidant, endophyte, preservative, Â turmericABSTRAKAktivitas mikroorganisme dan proses oksidasi dapat menyebabkan kerusakan pangan.

Sambiloto (Andrographis paniculata) has been used to treat malaria. In vitro research using parasite or through heme polymerization inhibition using andrografolide and in vivo using infected animal test have been done widely, however, heme polymerization inhibition from extracts with different polarity levels has not been studied yet. The aims of this study were to investigate the heme polymerization inhibition activity and toxicity of sambiloto leaf extracts. Sambiloto leaf extracted with gradually maceration using n-hexane, ethyl acetate, and 70% ethanol respectively. Heme polymerization inhibition activity was used as in vitro antimalarial test. Brine shrimp lethality test (BSLT) was used to determine toxicity of the extracts. Phytochemically screening was done for all extracts qualitatively. The results of this study were n-hexane, ethyl acetate, and 70% ethanol extracts had heme polymerization inhibition activities withÂ IC50 values at 2,196.57; 1,235.54; and 1,157.24 Î¼g/mL respectively. N-hexane, ethyl acetate, and 70% ethanol have LC50 values at 1,155.79; 1,133.89; and 5,229.15 Î¼g/mL respectively. 70% ethanol extract contains alkaloid, flavonoid, steroid/triterpenoid, saponin, and tannin. N-hexane and ethyl acetate extracts has only contains alkaloid and flavonoid. 70% ethanol, ethyl acetate, and n-hexane extracts of sambiloto leaf have ability to inhibit heme polymerization and also non toxic to Artemia salina larvae. Â Abstrak Sambiloto (Andrographis paniculata) telah lama digunakan untuk mengobati malaria. Penelitian in vitro dengan parasit maupun melalui penghambatan polimerisasi hem dengan senyawa andrografolida dan in vivo dengan hewan uji terinfeksi telah dilakukan, namun demikian belum ada penelitian tentang penghambatan polimerisasi hem ekstrak dengan tingkat kepolaran yang berbeda. Penelitian ini bertujuan untuk mengetahui aktivitas penghambatan polimerisasi hem dan toksisitas ekstrak daun sambiloto. Daun sambiloto diekstraksi secara maserasi bertingkat berturut-turut menggunakan pelarut n-heksan, etil asetat, dan etanol 70%. Uji antimalaria secara in vitro menggunakan metode penghambatan polimerisasi hem. Uji toksisitas menggunakan metode uji kematian larva Artemia salina (BSLT). Skrining fitokimia dilakukan secara kualitatif untuk seluruh ekstrak. Hasil penelitian menunjukkan bahwa ekstrak n-heksan, etil asetat, dan etanol 70% memiliki aktivitas penghambatan polimerisasi hem dengan nilai IC50 masing-masing sebesar 2.196,57; 1.235,54; dan 1.157,24 Î¼g/mL. Ekstrak n-heksan, etil asetat, dan etanol 70% masing-masing memiliki nilai LC50 sebesar 1.155,79; 1.133,89; dan 5.229,15 Î¼g/mL.

Malaria is still the leading cause of death worldwide with nearly half the worlds population at risk. Parasitic resistance to existing antimalarial drugs in the market makes the search for a source of new drugs from nature is very important. Therefore, the aims of this study are to determine in vitro antimalarial activity of endophytic fungi extract from turmeric root and to identify the selected isolate molecularly. Heme polymerization inhibition method was used as in vitro antimalarial assay. The selected isolate was thrn identified using ITS1, ITS2, and 5.8S sequences of rDNA. The result of this study obtained 16 isolates of endophytic fungi from root of turmeric plant with isolate code were of K.Cl.Sb.A1 - K.Cl.Sb.A16. All of the ethyl acetate extracts of isolated endophytic fungi have heme polymerization inhibition activity. K.Cl.Sb.A11 was the most active isolate on heme polymerization inhibition test with 94,31% at concentration of test material at 8 mg/mL and IC50 value at 1.84 mg/mL. Molecular analysis showed that K.Cl.Sb.A11 isolate was Penicillium sp. and potentially developed as an antimalarial drug.

Antioxidant Activity of Endophytic Fungi Cb.Gm.B3 Extract from Cinnamon (Cinnamomum burmanni) TwigsABSTRACTThere are many degenerative diseases that are caused by a free radical effect. Cinnamon (Cinnamomum burmanni) contains cinnamaldehyde compounds that have activity as a powerful antioxidant and fight free radicals. Endophytic fungi can be found in cinnamon plants living symbiotically. Endophytic fungi produce a variety of bioactive metabolites including antioxidants. This research was conducted to isolate endophytic fungi from C. burmanni plant which is active as antioxidant. Endophytic fungi isolation was carried out using surface sterilization method and cultivated in PDA media. Antioxidant activity test was performed using free radical 2.2-diphenyl-1-picrylhydrazyl (DPPH) method. Selected isolates were then identified molecularly to determine their species. A total of nine fungi were isolated from cinnamon twigs. The result showed that the highest antioxidant activity was obtained from Cb.Gm.B3 with IC50 of 13.219 ± 0.755 µg/mL. The selected isolate Cb.Gm.B3 taxonomically has a high similarity with Neofusicoccum parvum isolate PEL23 (Accession no: KY053054.1).Keywords: antioxidant, Cinnamomum burmanni, 2.2-diphenyl-1-picrylhydrazyl, endophytic fungi, Neofusicoccum parvum ABSTRAKKayu manis (Cinnamomum burmanni) mengandung senyawa sinamaldehid yang memiliki aktivitas sebagai antioksidan kuat dan dapat menangkal radikal bebas.
