18 β-Glycyrrhetinic Acid is an aglycone of the triterpenoid Glyccyrrhizic acid, which is found in liquorice. inhibits the PGDH (15-hydroxyprostaglandin dehydrogenase) leading to increased prostaglandin concentration in the digestive system. Also investigated for potential antibiotic activities.
参考质量标准:中国企标水分 ≤13% 灰分 ≤15% 熔点 220℃
比旋光度:165 ° (c=1, CHCl3,on dry ba)
上游原料:乙醇 --> 乙醇溶液 --> 蔗糖 --> 甘草酸 --> 甘草 --> SIS --> 甘草酸三铵盐
方法二:由豆科植物基草（Glycyrrhiza uralen-sis fisch）的根茎中提取的甘草酸，制成铵盐后再经水解而得。甘草为我年生草本，主产于内蒙古和甘肃等地。甘草的根及根茎主要含甘草甜素，为甘草酸（Glycyrrhiz-ic acid）的钾、钙盐，是甘草的甜味成分。甜约为蔗糖的50倍。将粉碎后的甘草加水加热，连续逆流提取，分离除去草渣杂质，得水溶液。蒸发、浓缩，搅拌下加硫酸pH2-3。静置沉淀，除去上清液。沉淀物用水洗尽硫酸根，加热浓缩浓缩，熬制成甘草酸膏。将甘草酸膏粉碎，用95%乙醇加流提取2-3次，每次3h，得乙醇溶液。经过滤后搅拌通氨至pH为7-7.5。再过滤，得甘草酸三铵盐粗品，用冰醋酸精制，即为米黄色的甘草酸单铵盐。将甘草酸单铵盐加入5%硫酸水溶液中，搅拌加热至近沸，回流水解15h，过滤、水洗得甘草次酸粗品。经重结晶、脱色即得含量在92%以上的基草次酸。以甘草计，总收率约0.5%。
