In the present study hydrodistd. essential oil and total methanol extracts of Tanacetum argenteum subsp. flabellifolium have been evaluated for their antimicrobial and antioxidant effects. The chem. composition of the oil and the crude extract were determined by GC/FID, GC/MS and LC/DAD/ESI-MS systems resp. β-thujone (47.1%), α-pinene (19.1%) and α-thujone (10.5%) were the main compounds of the essential oil while the 5-O- eaffeoquuinic acid, 1,5-O-dieafteoquuinic acid. 4,5-O-dicaffeoquuinic acid were identified as flavonoid content of the crude extract The oil and the methanol extract were demonstrated moderate antimicrobial effects (MIC range; 0,062-2,0 mg/mL) against 21 different pathogenic micro organism. Total phenolic content was determined as 63 mg GAE in g extract and the DPPH radical scavenging effect was determined as 0.16 mg/mL (IC50) and TEAC was determined as 0.21mMol. In the experiment, the researchers used many compounds, for example, Isopentyl 3-methylbutanoate (cas: 659-70-1COA of Formula: C10H20O2).
Isopentyl 3-methylbutanoate (cas: 659-70-1) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.COA of Formula: C10H20O2
