Abstract
Essential oil of Elettaria cardamomum (Green cardamom) is effective in the treatment of various disease conditions. Globally, Guatemala is the leading producer of green cardamom fruits. Green-cardamom fruits from Guatemala were purchased from a Saudi Arabian market. The Guatemala cardamom essential oil (GCEO) was extracted using hydro-distillation method, and analyzed using gaschromatography/ mass-spectrometry (GC-MS). The antioxidant and anti-inflammatory activities were studied using 2,2-diphenyl-1-picrylhydrazyl-hydrate, ferric-chloride, bovine serum-albumin and proteinase inhibitory assays. GC-MS results confirmed the presence of α- terpinyl acetate and 1,8-cineole as major components. The antioxidant and anti-inflammatory activities of GCEO were found to be significant compared with those of standard ascorbic acid and ibuprofen, respectively. The molecular-docking study revealed the considerable binding potential of α-terpinyl acetate and 1,8-cineole with human-peroxiredoxin-5, tyrosine-kinases and Human-5-LOX receptors. The in-silico activity prediction analysis confirmed the antioxidant and anti-inflammatory potential, whereas the pharmacokinetics confirmed the safety of most of the GCEO compounds.
