Isolation, identification, structural elucidation and bioactivity of Heneicos-1-ene from Coriandrum sativum L. foliage

Abstract

Coriander foliage is a distinctive spice employed on a daily basis in curry and other Indian traditional food preparations mainly for the unique flavour attributes and health benefits. Radical scavenging activity has been demonstrated previously for coriander foliage. However, specific molecules responsible were not identified. A new molecule was isolated via chromatographic technique, and its structure was established by employing multinuclei and multidimensional NMR and HRMS techniques. The identified molecule Heneicos-1-ene was also screened for radical scavenging activity and antimicrobial activity, wherein it displayed radical scavenging activity of 89.6 ± 0.62% at 200 ppm, and also exhibited substantial antimicrobial activity against E. coli and Salmonella typhi.
