Abstract

The nutritional components in fresh flower bud of two forms of Hibiscus syriacus L. including form. elegantissimus and form. amplissimus were analyzed. The results show that water content of form. elegantissimus and form. amplissimus is 88.67% and 83.86%,respectively,and contents of crude protein, crude fat and crude ash are 1.58% and 2.85%,0.28% and 0.43%,0.88% and 1.36%, respectively. Contents of Ca, Fe and Zn in fresh flower bud of two forms are higher with a value of 990 and 2 600 μg·g-1,16 and 28 μg·g-1,6.0 and 7.2 μg·g-1,respectively,and both of two forms contain a certain content of Se. Contents of V A and V E are higher with a value of 1 570 and 4 370 IU·kg-1,11.5 and 18.9 IU·kg-1,respectively. There are sixteen amino acids including eight essential amino acids in fresh flower bud of two forms, and content of Glu is the highest and that of Met is the lowest with a value of 3.20 and 3.50 mg·g-1,0.26 and 0.31 mg·g-1,respectively. It is concluded that the basic nutritional components in fresh flower bud of form. elegantissimus and form. amplissimus are consistent, but the mineral and vitamin contents in the latter are higher than those in the former, while amino acid content in the latter is lower than that in the former. It is suggested that nutritional components in flower bud of different forms of Hibiscus syriacus are various, and it needs to make a deep and detailed study.
