 Main volatiles found in the vacuum headspace concentrates of N.pseudonarcissus were (E)-ocimene (30%) and (Z)-ocimene (0.4%), (E,E)-α-farnesene (10%), 3,5-dimethoxytoluene (7%), and 1,4-dimethoxybenzene (5%). \\ Main volatiles found in the vacuum headspace concentrates of N.pseudonarcissus were (E)-ocimene (30%) and (Z)-ocimene (0.4%), (E,E)-α-farnesene (10%), 3,5-dimethoxytoluene (7%), and 1,4-dimethoxybenzene (5%). \\

 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. \\
