| HS-SPME/GC/MS of homogenized Narcissus pseudonarcissus cv. ‘Ice Follies’ petals showed ocimene (20.2%), hexanal (9.4%), 3-hexene-1-ol (9.3%), δ-3-carene (7.1%), α-pinene (6.9%), myrcene (5.6%), limonene (2.7%), benzene (3.9%), and 4-ethyl-pyridine (3.9%) as main volatiles. Minor components were α-farnesene (0.18%), bergamotene (0.71%), neryl acetate (0.57%), and phenol (0.93%) e.g. \\ | HS-SPME/GC/MS of homogenized Narcissus pseudonarcissus cv. ‘Ice Follies’ petals showed ocimene (20.2%), hexanal (9.4%), 3-hexene-1-ol (9.3%), δ-3-carene (7.1%), α-pinene (6.9%), myrcene (5.6%), limonene (2.7%), benzene (3.9%), and 4-ethyl-pyridine (3.9%) as main volatiles.

| The main alkaloid of the bulbs, galanthamine, could be extracted from the plant matrix using supercritical fluid extraction (SFE) with supercritical CO2. 303 μg/g was the optimum galanthamine yield, other N. pseudonarcissus alkaloids such as O-methyllycorenine and haemanthamine were also obtained. \\ | The main alkaloid of the bulbs, galanthamine, could be extracted from the plant matrix using supercritical fluid extraction (SFE) with supercritical CO2. 303 μg/g was the optimum galanthamine yield, other N. pseudonarcissus alkaloids such as O-methyllycorenine and haemanthamine were also obtained. \\ |
