Anti-meningitis agent potentially of Syzigium Cumini Essential oil by GC-MS

Abstract

The essential oil from fruit of Syzygium cumini (Myrtaceae), endemic to Indonesia, was investigated by using GC and GC-MS. Forty-six components represented of the total oil were identified. The major components of the essential oil were 1,2,3-Propanetriol (20.32%), octadecanoic acid (16.13%), glycerine-1-oleate-3-palmitate (12.00%), 9,12-Octadecadienoic acid (6.49%) and Heptadecyl acetate (5.52%). The bio-activity of the major components of essential oil of S. cumini was investigated by the PASS-online bio-activity prediction software. The major components of essential oil of S. cumini exhibited antibacterial activities. The antibacterial activity present in the essential oil of S. cumini has the potential to be used as an anti-meningitis bacterial. Further research is needed to test the definitive antibacterial ability of the compounds contained in S. cumini essential oil…

Antiacne and Antibacterial Bioactivity Properties of Teak (Tectona grandis) Flower Essential Oil

“…The GC-MS method is very suitable for volatile essential oils. 18,19 Before the real operation, the instrument was checked for gas flow starting at a low flow rate by opening the main and secondary valves on the carrier gas tank until it showed the 15-psi needle; this allows 2-5 mL/min carrier gas flow for the packed column or 0-5 mL/min for the capillary column. The column was heated to the desired initial temperature.…”

“…Finally, the E-oil was analyzed with GC or GC-MS (sealed and stored in cold storage away from light, if necessary). 16,17,18 .…”

“…10,11,15 Isolation of bioactive compounds by distillation of essential oils is reported to be able to isolate more volatile bioactive compounds compared to other extraction methods. 16,17,18 Therefore, this research aim is the important of study the bioactive compound profile of teak flower essential oil and test its potential as an antibacterial on Propionibacterium acnes to treat acne. The approach to providing the outcomes of this research objective was carried out by isolating essential oils from teak flowers using steam distillation.…”
