Lasia spinosa (L.) Thwaites is a widely used ethnomedicinal plant in Bangladesh. In this study, we investigated phenolic contents, volatile compounds and fatty acids, and essential oil components of extracts prepared from aerial parts of the plant. The main volatile compounds were Me ester of oleic acid, palmitic acid and stearic acid as determined by GC/MS. Phenolic contents of the extracts were determined qual. and quant. by HPLC/TOF-MS. Six phenolic compounds (syringic acid, morin, gentistic acid, 4-hydroxybenzoic acid, cinnamic acid, and apigenin) were found in the extracts GC/MS anal. of steam distilled essential oil showed camphor, α-pinene and δ-3-carene as the main constituents. In DPPH radical scavenging assay, the highest free radical scavenging activity was observed for the methanol extract with an IC50 value of 0.48 ± 0.04 mg/mL, whereas, in metal chelating activity on ferrous ions (Fe2+) assay, the highest chelating activity was observed for hexane extract (IC50 = 0.55 ± 0.08 mg/mL). The extracts and essential oil were tested against five severe human pathogenic bacteria using disk diffusion assay and subsequent MIC values were also determined All the extracts (except methanol extract) and the essential oil were found to possess potential antimicrobial activity with corresponding inhibition zone and min. inhibitory concentration (MIC) ranging from 9-23 mm and 62.5-500μg/mL. This study has been explored the plant Lasia spinosa can be seen as a potential source of biol. active compounds This study involved multiple reactions and reactants, such as Methyl nonadecanoate (cas: 1731-94-8Formula: C20H40O2).
Methyl nonadecanoate (cas: 1731-94-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Formula: C20H40O2
