comparative analysis of the odorants of cilantro (coriandrum sativum l.) and culantro (eryngium foetidum l.,) as aromatic crop mimics of family: apiaceae

Purpose: fresh leaves of cilantro (coriandrum sativum l.), and culantro (eryngium foetidum l.,) are used interchangeably based on similar odor, aroma and flavor and considered culinary substitutes. cilantro is ethnically called “false coriander” and a mixed method approach to determine the possibility of crop mimicry was reviewed. critical analysis was done on botanical, phylogenic traits and trees, dendogram, molecular, and phytochemical similarities of the odorants. findings: the study indicated that c. sativum and e. foetidum, belonged to two different subfamilies of apiaceae, appeared morphologically divergent, but phytochemically similar in aroma and odorants indicating a classical example of convergent evolution in the plant kingdom. five odor clusters with over 20 similar phytochemicals with the co‐elution of e‐2‐ alkenals and e‐2‐alken‐1‐ols were identified. greater levels e‐ 2‐dodecenal in e. foetidum (63.5%) compared to c. sativum, (26.0%) accounted for dominant odor which is found in crop mimics due to selective agricultural practices and the evolution of agricultural races of weeds. multiple mechanisms explained how plant mimic evolved from “de‐domestication” and hybridization. evolutionary origins and genetic diversity characterized genomics of e. foetidum as an aggressive aromatic pungent weed, and c. sativum as a fragrant herb. limitations: there are no limitations in this review. directions for future research: organoleptic preference for the essential oils of coriander seeds and a clearer understanding of the phytochemical relationships between c. sativum and e. foetidum are required.
