-"In case of narcissus, fragrance is extracted via hexane or petroleum ether solvent from flowers resulting in 0.2-0.3% concrete or by supercritical CO 2 extraction resulting in a yield of 0.41% (Ehret et al., 1992; Ferri et al., 2009). In case of solvent extraction, it takes 1000 kg of flowers to produce 2kg of concrete or 750 g of absolute and the relative low productivity of absolute from narcissus makes it an expensive product, restricted to luxury perfumes." \\ +"In case of narcissus, fragrance is extracted via hexane or petroleum ether solvent from flowers resulting in 0.2-0.3% concrete or by supercritical CO2 extraction resulting in a yield of 0.41% (Ehret et al., 1992; Ferri et al., 2009).
