Chemical Composition of Broussonetia Papyrifera Flowers

Abstract:

Corolla and receptacle of Broussonetia papyrifera from South China were analyzed separately for chemical composition. In this plant’s corolla，the crude protein, crude fat and carbohydrates were 7.08％, 3.72％ and 64.73% respectively in dry weight. In the receptacle, the crude protein, crude fat and carbohydrates were 4.75％, 8.08％ and 67.03% respectively. Unsaturated fatty acids concentration was 68% of total fatty acids. The percentage of the essential amino acids (EAAs) in total amino acids was 34.52%in corolla and 27.96% in receptacle. Furthermore，many mineral celements composition and vitamins are rich in B. papyrifera flowers. In corolla, calcium is 10015 mg/kg, magnesium is 1989.6 mg／kg, zinc is 62.6 mg／kg, iron is 306.6 mg／kg, V_E is 1.35mg/100g．These results suggest that, the fiowers could be used in dietary supplements preparations or as food additives.
