摘要： 金花葵的花由于其含有丰富的黄酮类成分，在食用、药用与保健方面有着较高的利用价值。为了比较金花葵（Hibiseu manihot L.）鲜花、干花和花苞不同时期入药方式化学成分差异，确定金花葵花最佳药用时期，本实验采用超高效液相-串联四级杆飞行时间质谱（UPLC-QTOF-MS）对金花葵干花、花苞和鲜花的全组分进行分析，共鉴定出141种化合物，其鲜花中部分黄酮类和有机酸类化合物，含量较干花和花苞中高。且鲜花和干花较花苞的药效成分多且含量高。结果表明金花葵在不同入药方式中花所含的化学成分存在差异，应根据需要采摘使用。本研究为金花葵的合理开发利用提供理论依据。

Abstract:

The flower of Hibiseu manihot L. has rich flavonoid compositions which have high utilization value in food,medicine and health care.To compare the chemical composition differences in the flowers of H. manihot with different medicinal methods and determine the best medicinal period of H. manihot This experiment uses ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) analyzed the complete components of dried flowers,buds and fresh flowers of H. manihot.A total of 141 compounds were identified.Some of the flavonoids and organic acid compounds in the fresh flowers were higher than those in dried flowers and buds.In addition,fresh flowers and dried flowers have more medicinal ingredients and higher content than buds.The results showed that there are differences in the chemical composition of the flowers in different ways of medicine,and it should be picked and used according to the needs.All in all,this research provides a theoretical basis for the rational development and utilization of H. manihot.

Key words: Hibiseu manihot L., fresh flowers, dried flowers, buds, UPLC-QTOF-MS
