碱性食品对人体是很重要,它能使人体的体液呈相对碱性,是人体健康的标志。并能减少和降低很多疾病的发生率。 碱性食品,同酸性食品相对。碱性食品的划分不是根据口感,而是根据食物在人体内最终的代谢产物来划分的。如果代谢产物内含钙、镁、钾、钠等阳离子,即为碱性食物; 反之,硫、磷较多的即为酸性食物,所以醋和苹果味道虽酸却是碱性食物。
因此,从理论上讲,弱酸性药物(阿司匹林)酸性介质中(腔)弱碱性药物(奎宁)易吸收。
Thus theoretically, weakly acidic drugs (eg, aspirin) are more readily absorbed from an acid medium (stomach) than are weak bases (eg, quinidine).
结论:酸碱双点电位法具有简便、快速、准确等特点,在有机弱酸弱碱性药物分析中有一定的实用前景。
Conclusion: The acid base doub1e points potentiometric method is simple, rapid and precise, and has prospect of application in analysing organic weak acid and base medicines.
