枸杞是一种名贵药材,但是对枸杞叶和果把,长期以来,从未加以利用,近年来把枸杞叶和果把加工成保健饮料——枸杞茶,远销国外,另一方面对枸杞叶和果把进行了有效成份的分离鉴定和药理的初步研究工作,发现其对增强机体免疫能力和降血压等方面有一定的效果,并且在有些方面还超过了枸杞子,为此我们对枸杞叶和果把中的微量元素锂的含量进行测定研究,根据有关文献拟定了用火焰原子吸收光谱法测定了样品中的锂含量,方法简便、准确、精密度和回收率达到了满意的结果。
Chinese wolfberry is a valuable medicinal herbs, but the wolfberry leaves and fruit, for a long time, has never been used in recent years, the wolfberry leaves and fruit into health drink - wolfberry tea, sold abroad, on the other hand wolfberry leaves And fruit to carry out the separation and identification of active ingredients and pharmacological preliminary study and found that it has some effect on enhancing immunity and blood pressure and other aspects, and in some aspects also surpassed the wolfberry fruit, for which we wolfberry leaves And fruit of the determination of the content of trace elements lithium, according to the literature developed by flame atomic absorption spectrometry determination of the sample of lithium content, the method is simple, accurate, precision and recovery rate to achieve satisfactory results.
