Embodiment 1
[0047] Narcissus Ming Fumarate
[0048] The compound narcissus 2.71 g (0.01 mol) and fumaric acid 1.17 g (0.01 mol) were dissolved in 70 ml of boiling ethanol. The hot solution was filtered through diatomaceous earth, then slowly cooled under gentle stirring, and left for several hours in a temperature environment of 0-5°C to precipitate narcissin fumarate crystals, and then filter out narcissus luminal fumarate crystals, Washing with ethanol and drying under vacuum at 50°C yielded 3.87 g of product.
Embodiment 2
[0050] Narcissus Ming Fumarate
[0051] 2.68 g of the compound narcissus fumarate and 1.17 g of fumaric acid were stirred in 70 ml of refluxing ethanol until all the solids were dissolved. Activated carbon was added, the hot solution was filtered through diatomaceous earth, and the temperature was cooled to room temperature while stirring. After standing for several hours in a temperature environment of 0-5°C, narcissin fumarate crystals were precipitated, and the narcissin fumarate crystals were filtered out, washed with ethanol and dried under vacuum at 50°C to obtain 3.85 g of product.
