“…The present experiment is similar to the study of Shekar et al [ 36 ]; they showed 75.54% inhibition of S. mutans bacteria. Nallathambi and Bhargavan [ 37 ] recorded the existence of bioactive compounds in the moist extract of C. dactylon by using a gas chromatograph and a mass spectrometer with a quadruple double-focusing mass analyzer and detected eight compounds which included Alanine, 9, 12-octadecadienoic acid, n-Hexadecenoic acid, oleic acid, 3-octyl-methyl-ester trans, phytoderivatives and coumarine, 3-(2-4-dinitrophenyl), etc. The compounds of phytol derivates are used due to their antimicrobial, anticancer, anti-inflammatory, antioxidant, and diuretic properties [ 23 ].…”

Streptococcus mutans bacteria form a biofilm called plaque that causes oral diseases, including tooth decay. Therefore, inhibition of biofilm formation is essential to maintaining good oral health. The health and nutritional benefits of Cynodon dactylon are well documented, but very little is known about its use to treat against oral diseases. The aim of this study was to detect the adhesion strength of the S. mutans bacterial biofilm in 100 cases in the Rajshahi region and evaluate the inhibitory activity of different compound extracts of C. dactylon on the S. mutans bacterial biofilm by determining the composition of isolated compounds using phytochemical analysis. Nuclear magnetic resonance (NMR) spectroscopy confirmed that three specific compounds from C. dactylon were discovered in this study: 3,7,11,15 tetramethyl hexadec-2-4dien 1-o1, compound 3,7,11,15 tetramethylhexadec-2-en-1-o1 from phytol derivatives, and stigmasterol. Results indicated that the compound of 3,7,11,15-tetramethyl-hexadec-2-en-1-ol exhibited higher antibiofilm activities on S. mutans than those of the other compound extracts. A lower level of minimum inhibitory concentration was exposed by 3, 7, 11,15 tetramethyl hexadeca-2-en-1-o1 (T2) on S. mutans at 12.5 mL. In this case, the compound of 3,7,11,15 tetramethyl hexadec 2en-1-o1 was used, and patients showed a mean value and standard error reduced from 3.42 ± 0.21 to 0.33 ± 0.06 nm. The maximum inhibition was (80.10%) in the case of patient no. 17, with a value of p < 0.05 found for S. mutans to which 12.5 μL/mL ethyl acetate extract was applied. From these findings, it may be concluded that C. dactylon extracts can be incorporated into various oral preparations to prevent tooth decay.

“…A chromatogram evaluation technique uses a thermal conductivity detector to determine gas mixture separation. [36][37][38] Helium (He) is primarily employed as a carrier gas to flow continuously at a flow rate of 25 mL/min, the chamber temperature is kept constant at room temperature (27°C), and the detector and filament temperatures are adjusted to 125 and 225°C, respectively. The make and model of GC-MS are Agilent GC: 7980B Agilent MS: 5977A with autosampler Column available: DB5MS and DB1MS, used in the investigation.…”

Anthropogenic activites release greenhouse gas emissions into our atmosphere, especially carbon dioxide (CO2). This abundant accumulation of CO2 generates numerous problems like global warming and climate change. However, research has been conducted to capture CO2 from significant single‐point emitters like compression ignition (CI) engines, backup generators, and distributed power production plants. Moreover, research has also been done on post‐combustion adsorption chamber to capture CO2 emissions from small stationary engines. Biomass‐based activated carbon as an adsorbent for capturing CO2 from engine exhaust has recently been investigated. Three biomass‐based adsorbents, (a) coconut shell adsorbent, (b) rice husk adsorbent and (c) eucalyptus wood adsorbent, are used in the capture unit to trap CO2 from the CI engine exhaust. This study uses a single‐cylinder, four‐stroke, air‐cooled, naturally‐aspirated, direct‐injection (DI) CI engine running at a constant speed of 1,500 rpm and producing power of 4.4 kW. The adsorption performance of adsorbent samples is investigated by coupling the adsorption chamber to the exhaust system of a test engine operated on diesel (D100) at various loads. Temperature swing adsorption (TSA) is used to regenerate the original adsorbent. The adsorbents’ adsorption capacities are evaluated by performing multiple adsorption–desorption test cycles using the same adsorbents. During TSA, CO2 released from the capture unit is further captured and stored in a gas bag. The captured gas sample is characterized through gas chromatography‐mass spectroscopy (GC‐MS) characterization to examine and ensure the gas adsorption efficacy of adsorbent samples. The outcomes of this research study are discussed and presented in detail. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.
