甘草酸(Glycyrrhizic acid 或 glycyrrhizinic acid)又称甘草皂苷甘草甜素(Glycyrrhizin),是甘草Glycyrrhiza glabra)根的主要甜味成分;在结构上是一种皂苷。可用作食品和化妆品中的乳化剂凝胶形成剂。其糖苷配基甘草次酸,在日本被用于降低慢性C型肝炎患者肝癌的风险的前体药物[3] [4]

不良影响

[编辑]

通过食用黑甘草使用甘草酸的最广泛报道的副作用是降低血钾水平,对体液平衡神经功能有影响。[5] [6] 长期服用黑甘草,即使是适量,也会导致压升高, [6]可能导致心律不齐 ,以及与处方药的不良反应。 [5]

其对体液的影响与肾脏内皮质醇代谢的抑制,和随后对盐皮质激素受体的刺激, [7]以及血液中肾素、钾和醛固酮的水平降低有关,这些因素共同导致血压升高。 [6]

根据摄取黑甘草的量和频率,其他副作用可能包括: [5] [8]

研究

[编辑]

正在对甘草酸进行实验室和初步临床研究,以确定其对常见病毒 (如C型肝炎)的可能活性。[4] 甘草甜素在体外抑制酶11β-羟基类固醇脱氢酶[8]

药代动力学

[编辑]

口服摄入后,甘草酸首先被肠道细菌水解为18β-甘草次酸(Enoxolone)。 从肠道完全吸收后,18β-甘草次酸被代谢成肝脏中的3β-单葡糖醛酸-18β-甘草次酸。然后该代谢物在血流中循环。主要部分被胆汁清除,只有一小部分(0.31-0.67%)被尿液清除。 [9] 口服摄入600mg甘草酸后,1.5至14小时后尿液中出现代谢物。1.5至39小时后达到最大浓度(0.49至2.69mg / l),并且在2至4天后仍可在尿液中检测到代谢物。[9]

调味特性

[编辑]

甘草酸是甘草根浸提后,在水中煮沸而得的提取物[10] 甘草提取物(甘草酸)在美国作为液体、糊剂或喷雾干燥粉末出售。 [10] 当在规定量范围时,它被批准用作制造食品,饮料,糖果, 膳食补充剂调味品中的香料和香味剂[10]它的甜度是蔗糖(食糖)的30至50倍。 [8] [11]
