摘    要:利用热回流法和超声波法提取细果角茴香中的总黄酮,结合NaNO2-Al(NO3)3-NaOH体系分光光度法测定细果角茴香中的总黄酮含量,并对细果角茴香中总黄酮的提取方法进行优化。结果表明:利用超声波法提取细果角茴香中的总黄酮效果较好;且在甲醇浓度为70%、料液比为1:20、超声波提取2次、提取时间分别为2.0h和1.5h的条件下提取效果最好,测得总黄酮的含量为15.44mg/g。NaNO2-Al(NO3)3-NaOH体系分光光度法操作简捷,测定结果准确可靠。

关 键 词:细果角茴香  总黄酮  提取  含量测定

Abstract:Total flavonoids in H. leptocarpum was extracted by hot reflux method and ultrasonic extraction method, and its content was determined by NaNO2-Al (NO3 )3-NaOH spectrometry. The results showed that ultrasonic method was more suitable than hot reflux method, and the optimum extraction condition was 70% methanol solution, solid-liquid ratio 1:20 (W/V), ultrasonic treatment twice with the time of 2. 0 h and 1.5 h. Total flavonoids content in H. leptocarpum was about 15.44 mg/g. NaNO2-Al (NO3 ) 3-NaOH spectrometry method was easy to operate and the results were accurate.
Keywords:Hypecoum leptocarpum Hook  f  et Thoms    Total flavonoids  Extraction  Content determination
