Year: 2024

Type: article

Abstract: Citrus limon (L.) Osbeck is considered as one of the most significant horticultural as well as essential oil crop. However, the significance of the fruit peels left after the utilization of the sour fruit find limited importance and these leftover peels are rich in essential oil. Lemon peel essential oil (LPEO) finds used in the fragrance, food, cosmetic, and pharmaceutical industries. In this study lemon peel were used for isolation of essential oil by hydro-distillation, analyzed by GC-FID and GC-MS and was further subjected to in vitro anti-oxidant (DPPH, ABTS), anti-inflammatory, anti-tyrosinase, genotoxicity and anti-diabetic assays. The essential oil analysis has revealed limonene as major compound (38.08%) along with other minor compounds namely, α-citral (12.02%), decanal (8.14%) and neral (7.36%). The total amount of citral (α-citral and neral) was found to be 19.38%, comparatively higher compared to previous reports. LPEO was found to exhibit very strong tyrosinase inhibition activity along with good alpha-amylase inhibition. The results from this study further strengthen the immense potential of LPEO as an anti-diabetic and skin whitening agent. The results framed from this study will further strengthen the position of earlier works on biological activities of C. limon besides providing a descriptive work on the potential of Assam LPEO.
