甘草酸（Glycyrrhizic acid 或 glycyrrhizinic acid）又稱甘草皂苷、甘草甜素（Glycyrrhizin），是甘草（Glycyrrhiza glabra）根的主要甜味成分；在結構上是一種皂苷。可用作食品和化妝品中的乳化劑和凝膠形成劑。其糖苷配基是甘草次酸，在日本被用於降低慢性C型肝炎患者患肝癌的風險的前體藥物。^[3] ^[4]

不良影響

通過食用黑甘草使用甘草酸的最廣泛報導的副作用是降低血鉀水平，對體液平衡和神經功能有影響。^[5] ^[6] 長期服用黑甘草，即使是適量，也會導致血壓升高， ^[6]可能導致心律不齊，以及與處方藥的不良反應。 ^[5]

其對體液的影響與腎臟內皮質醇代謝的抑制，和隨後對鹽皮質激素受體的刺激， ^[7]以及血液中腎素、鉀和醛固酮的水平降低有關，這些因素共同導致血壓升高。 ^[6]

根據攝取黑甘草的量和頻率，其他副作用可能包括： ^[5] ^[8]

水腫
嗜睡
頭痛
癱瘓
瞬時失明
扭轉性室速
心動過速
心臟驟停
睪酮減少
早產
急性腎衰竭
肌肉無力
肌病
肌紅蛋白尿
橫紋肌溶解
體重增加

研究

正在對甘草酸進行實驗室和初步臨床研究，以確定其對常見病毒（如C型肝炎）的可能活性。^[4] 甘草甜素在體外抑制酶11β-羥基類固醇脫氫酶。 ^[8]

藥代動力學

口服攝入後，甘草酸首先被腸道細菌水解為18β-甘草次酸（Enoxolone）。從腸道完全吸收後，18β-甘草次酸被代謝成肝臟中的3β-單葡糖醛酸-18β-甘草次酸。然後該代謝物在血流中循環。主要部分被膽汁清除，只有一小部分（0.31-0.67％）被尿液清除。 ^[9] 口服攝入600mg甘草酸後，1.5至14小時後尿液中出現代謝物。1.5至39小時後達到最大濃度（0.49至2.69mg / l），並且在2至4天後仍可在尿液中檢測到代謝物。^[9]

調味特性

甘草酸是甘草根浸提後，在水中煮沸而得的提取物。^[10] 甘草提取物（甘草酸）在美國作為液體、糊劑或噴霧乾燥粉末出售。 ^[10] 當在規定量範圍時，它被批准用作製造食品，飲料，糖果，膳食補充劑和調味品中的香料和香味劑。 ^[10]它的甜度是蔗糖（食糖）的30至50倍。 ^[8] ^[11]
