Apart from the Carbohydrates and proteins in significant amounts, it also contains Ca 709, Mg 330, P 409, K 1267, Na 35, Zn 5 and Riboflavin 2 mg/100 g respectively of the edible portion. The extract of the coriander individually or in combination with other spices finds potential therapeutic applications. The Indian variety of coriander usually contains up to 0.4% of essential oil which contribute the characteristic aroma to the species. The major ingredient in the essential oil is linalool (58-75%), and other significant compounds include α-Pinene, terpineol, cuminal, citronellol, Geraniol and geranyl acetate. The nonvolatile compounds include, α-tocopherol, stigmasterol, ergost-5-en-3-ol, β-amyrin, stigmast-4-en-3-one along with other bioactive flavonoid constituents, quercetin 3-glucuronide, isoquercetin and rutin other minor constituents. Phenolic acids are the major components responsible for medicinal properties of coriander and seven phenolic acids, tannic, Gallic, caffeic, cinnamic, chlorogenic, ferulic, and vanillic acids are reported. Clevenger distillation is employed in large for the isolation of essential oil, though, the advanced extraction methods such as supercritical extraction is being explored by the industry. Also, the storage conditions play an important role as it is highly prone 89 Conclusion for infestation. The reports indicate that the storage of the processed seeds under dark conditions showed better stability (for example the linalool content retained from 69.75% to 68.75% over a period of 12 months), whereas, it has come down from 69.75% to 23.51%. Various parts of coriander are being used for its potential applications.
