Abstract

Citral, a significant aldehyde monoterpene found in various kinds of lemongrass (Cymbopogon sp.), is used as an aromatherapy tool to decrease tension, anxiety, and depression, as well as a fragrance in soaps and other personal care items. Moreover, recent research has revealed that this substance has numerous important health benefits, including anti-oxidant, anti-inflammatory, anti-hyperglycemic, and anti-diabetic qualities, to mention a few. Citral is the major component of the lemongrass essential oil (LGEO). The percentage of citral found in commercially marketed LGEOs are quite fluctuating, therefore it is important to quantify the citral molecules in the commercially available LGEOs. In this study, a pioneering detection method for citral is presented using copolymerization of Methacrylic Acid and Styrene on the surface of a Quartz Crystal Microbalance (QCM) sensor. The fabricated sensor has yielded a high sensitivity of 0.0833 𝑯𝒛/𝒑𝒑𝒎 with a commendable correlation factor (𝑹𝟐) of0.9648. The applicability of this sensor is further enriched by its large linear operating range of (50-600) ppm. The potential of the sensor was further investigated by discriminating four four distinct commercially available LGEO depending on Citral concentration, which has produced a high separability index of 0.9562 when analyzed through Principal Component Analysis. This QCM-based measurement technique enhances citral detection possibilities with promising results thereby further widening the application areas for QCM based measurement.
