摘要
用硝酸、高氯酸混合酸消解样品,采用原子吸收光谱法,测定了河南大别山区野生葛不同部位即葛根、葛藤、葛叶及花蕾中铜、锌、铁、钙、镁的含量,并对其结果进行了分析。结果显示:葛根、葛藤、葛叶及葛花中含有丰富的宏量元素钙、镁和有益的微量元素铜、锌、铁。铜的分布量依次为:叶>花蕾>葛藤>葛根;锌的分布量依次为:叶>花蕾>葛藤>葛根;铁的分布量依次为:葛根>葛藤>叶>花蕾;钙的分布量依次为:叶>葛根>花蕾>葛藤;镁的分布量依次为花蕾>葛根>叶>葛藤。测定结果为探讨中草药中宏量、微量元素与治疗心脑血管疾病功效的关系提供了有用的数据;测定结果还显示:葛叶中铜、锌、钙含量居其他部位含量之首,适宜大力开发葛叶产品。
The samples of pueraria lobata ohwi were digested by HNO3 ＋ HC104. Copper, zinc, iron, calcium and magnesium in pueraria lobata ohwi from Da Bieshan were successfully determined by flame atomic absorption spectrophotometry（FAAS）. The results showed that there are rich grand elements, such as Ca and Mg, and profitable elements, such as trace elements Cu, Zn and Fe, in pueraria lobata ohwi. The content sequence of metal elements is as follows： Copper： leaves〉flowers 〉rattans〉roots; Zinc： leaves〉 flowers〉 rattans〉 roots; Iron： roots〉 rattans〉 leaves〉 flowers; Calcium： leaves〉 roots〉 flowers 〉 rattans; Magnesium： flowers 〉 roots〉leaves〉rattans. The results provided useful data for discussing the relationship between the metal elements in pueraria lobata ohwi and the cure for cerebrovascular diseases and hypertension diseases.
