The chemical constituents of the extract were investigated using gas chromatography-mass spectrometry (GC-MS).Methods: Secondary metabolites from S. omiyaensis were produced by submerge fermentation using ISP2 medium with 3% NaCl (w/v) for 21 days. The culture filtrate was extracted with ethyl acetate. The chemical constituents were detected in the GC-MS analysis. Antibacterial activity was performed using disc diffusion and broth microdilution methods. Antioxidant activity was evaluated by determining the reducing power capacity and free radical scavenging assays.Results: The GC-MS analysis of the SCH2 extract revealed the presence of four compounds. The main constituents were 2-phenylacetamide (79%). The extract exhibited the highest zone of inhibition against some pathogenic bacteria such as Enterobacter cloacae, Klebsiella pneumoniae, and Bacillus subtilis. In addition, the lowest minimum inhibitory concentration (IC) and minimum bactericidal concentration values of extract were obtained for E. cloacae (0.125 and 4 mg/ml). The extract showed antioxidant potential with IC50 values of 2.078.13±24.58 μg/ml and 475.74±4.56 μg/ml for 2,2-diphenyl-1-picryl-hydrazyl and 2,2′-azino-bis[3-ethylbenzothiazoline-6-sulphonic acid] assays, respectively. The ferric reducing antioxidant power value of extract was 110.36±1.75 mmol FeSO4.7H2O/g extract.Conclusion: This study indicated that S. omiyaensis extract possesses antibacterial and antioxidant activities. GC-MS analysis revealed the presence of major chemical constituents, acetamide, and pyrrolopyrazine which could be responsible for the biological activities. S. omiyaensis extract could be used as a potential of natural antibacterial and antioxidant agents for pharmaceutical and medical applications.

Kasturi (Mangifera casturi) is a typical plant of South Kalimantan which has only been used for consumption because of its distinctive taste and aroma. Mangifera indica, which is in the same genus as Mangifera casturi, shows antioxidant, antibacterial, antifungal, and antidiarrheal activity, so it is suspected that this plant has the same activity. Crude methanol extract from the meat of Casturi mango was fractionated using n-hexane, ethyl acetate, and methanol-water. Testing for antibacterial activity and minimum inhibitory concentration (MIC) were carried out using the disk diffusion method (Kirby-Bauer). The positive control used was Chloramphenicol because it has an antibacterial range that is rather broad and the negative control used was 10% DMSO. The fraction that had the greatest antibacterial activity was the ethyl acetate fraction; with the formation of a clear zone of 7.98mm against Pseudomonas aeruginosa and 7.52mm against Bacillus cereus, with a minimum inhibitory concentration of 2mg/mL. The next test was a cell leakage analysis which revealed an increase in absorbance at MIC 1 and MIC 2. The Gas Chromatography – Mass Spectrometry (GC-MS) results from the ethyl acetate fraction revealed the presence of phenolic, flavonoid, and glycoide content, with the highest compound concentration of 5-Hydroxymethylfurfural. Keywords: Antibacterial, Extract, Ethyl acetate, fraction, Mangifera casturi Abstrak Kasturi (Mangifera casturi) merupakan tumbuhan khas Kalimantan Selatan yang selama ini hanya dimanfaatkan untuk dikonsumsi karena rasa dan aromanya yang khas. Mangifera indica yang masih satu genus dengan Mangifera casturi menunjukkan aktivitas antioksidan, antibakteri, antijamur, dan antidiare sehingga diduga tanaman ini memiliki aktivitas yang sama. Ekstrak kasar metanol daging buah mangga kasturi difraksinasi dengan menggunakan n-heksan, etil asetat, dan metanol-air. Pengujian aktivitas antibakteri dan kadar hambat minimum dilakukan dengan menggunakan metode difusi cakram (Kirby- Bauer). Kontrol positif yang digunakan adalah Chloramfenikol karena memiliki spektrum antibakteri yang cukup luas dan kontrol negatif yang digunakan adalah DMSO 10%. Fraksi yang memiliki aktivitas antibakteri terbesar pada penelitian ini adalah fraksi etil asetat dengan terbentuknya zona bening sebesar 7,98mm terhadap Pseudomonas aeruginosa dan 7,52mm terhadap Bacillus cereus dengan kadar hambat minimum 2mg/mL. Uji selanjutnya adalah uji kebocoran sel yang menyatakan adanya peningkatan absorbansi pada KHM 1 dan KHM 2. Hasil pemeriksaan Gas Chromatography – Mass Spectrometry (GCMS) dari fraksi etil asetat menyatakan adanya kandungan fenolik, flavonoid, dan glikosida dengan senyawa tertinggi yaitu 5-Hydroxymethylfurfural.

One new dolabellane (1) and two known diterpenoids stolonidiol (2) and clavinflol B (3) have been isolated from the ethyl acetate extract of the Indonesian soft coral Anthelia sp. A new compound 1 exhibited a moderate cytotoxicity against NBT-T2 cells at 10 µg/mL, while known compounds 2 and 3 showed cytotoxicity at 1 and 0.5 µg/mL, respectively. Structure of the new compound 1 was elucidated by interpretation of NMR spectroscopic data (1D and 2D NMR data) and mass spectrometry (ESIMS data) as well as comparison with those of related ones. This finding should be useful for anti cancer drug development of the promising dolabellane-types compound.
