摘要
对生姜不同部位进行了研究,以期提高生姜的综合利用。测定生姜老根、鲜根、茎、叶4个不同部位的黄酮、多酚、姜辣素和精油含量,并比较不同部位提取液的DPPH·、ABTS+·及·OH的清除能力。结果表明:生姜4个不同部位中的黄酮、多酚、姜辣素和精油含量大小顺序一致,依次为老根>鲜根>叶>茎;在抗氧化活性方面,老根提取液的总抗氧化活性最高,其次是鲜根、叶,而茎提取液最低。相关性分析发现,生姜不同部位提取液的DPPH·、ABTS+·及·OH自由基清除能力与黄酮、多酚和姜辣素含量均表现出一定的正相关。
In this study,different parts of ginger are explored in order to improve the comprehensive utilization of ginger.The content of flavonoids,polyphenols,gingerols and essential oils in four different parts such as old roots,fresh roots,stems and leaves of ginger are determined and the scavenging abilities of DPPH·,ABTS+·and·OH of extract from different parts are compared.The results show that the order of the content of flavonoids,polyphenols,gingerols and essential oils in four different parts of ginger is the same and which is old roots>fresh roots>leaves>stems.In the aspect of antioxidant activity,the total antioxidant activity of old roots extract is the highest,followed by fresh roots and leaves extract,and the stems extract is the lowest.The correlation analysis shows that the scavenging abilities of DPPH·,ABTS+·and·OH free radicals of extract from different parts of ginger are positively correlated with the content of flavonoids,polyphenols and gingerols.
