Abstract

OBJECTIVE

To analyze the floral volatiles of Polyonum cuspidatum flower.

METHODS

The floral volatiles of P. cuspidaturn flower were investigated by Headspace Sampler GC/MS.

RESULTS

21 compounds were separated and determined from P. cuspidatumrn, which amounted to 99.29% of the total volatiles. 5 compounds including (E)-2-hyexenoic acid methyl ester, 1-phenyl-l-pentanone, (E)-4-hexenoic acid methyl ester, 3-hexenoic acid methyl ester, 2-methyl-6-methylene-1 and 7-octadien-3-one were the main constituents existed in P. cuspidatum flower, which amounted to 63.23% of the total volatiles. Organic ester compounds amounted to 52.09% of the total volatiles. Hexenoic acid methyl ester compounds were most, which amounted to 85.66% of the total organic ester compounds. In addition, the 1-phenyl-1-pentanone and acetophenone were 16.30% and 4.33%, which amounted to 20.63% of the total volatiles.

CONCLUSION

The result of this research provides a scientific method for the reasonable exploitation and utilization of P. cuspidatum flower.

摘要

目的

分析虎杖花的挥发性成分。

方法

采用顶空进样气相色谱/质谱联用仪对虎杖花的挥发性成分进行研究。

结果

从虎杖花中分离鉴定出21种化合物，占挥发性成分总量的99.29%。其中（E）-2-己烯酸甲酯、1-苯基-1-戊酮、（E）-4-己烯酸甲酯、3-己烯酸甲酯、2-甲基-6-亚甲基-1,7-辛二烯-3-酮等5种化合物为虎杖花的主要成分，占挥发性成分总量的63.23%。有机酯类化合物占挥发性成分总量的52.09%。己烯酸甲酯类化合物最多，占有机酯类化合物总量的85.66%。此外，1-苯基-1-戊酮和苯乙酮分别占挥发性成分总量的16.30%和4.33%，二者共占挥发性成分总量的20.63%。
