甘肃地区沙棘叶中黄酮类物质含量测定

Determination of flavonoids in Seabuckthorn Leaves of Gansu

【目的】研究甘肃不同地区及不同生长时期沙棘叶中的黄酮类物质含量,为评价及开发利用沙棘叶资源提供科学依据。方法:采用高效液相色谱法测定沙棘叶中的黄酮类物质含量,并进行比较分析。结果:沙棘叶中总黄酮平均含量为35mg/g,富含杨梅素(0.62mg/g)、异鼠李素(0.39mg/g)。结论:有必要对甘肃沙棘叶进行深层面的研究,以便科学合理利用沙棘资源。

【Objective】The contents of flavonoids in seabuckthorn leaves from different regions and growing periods in Gansu Province were studied to provide scientific basis for the evaluation and utilization of seabuckthorn resources.Methods:The content of flavonoids in seabuckthorn leaves wera determined by HPLC and compared.Rrsults:The contents of total flavonoids in seabuckthorn leaves were 35mg/g,which were rich in myricetin(0.62 mg/g),isorhamnetin(0.39 mg/g).Conclusion:It is necessary to further research on Gansu seabuckthorn leaves in order to make scientific and rational use of seabuckthorn resources.
