Alkali salts
[edit]The alkalisaltsof psyllic acid are precipitated when alcoholic solutions of the acid and analkali hydroxideare mixed. The silver and barium salts can be obtained by adding aqueous alcoholic solutions ofsilver nitrateandbarium chlorideto alcoholic solutions of the acid. The following salts have been analyzed: C33H65O2Na, C66H130O4Ba, and C33H65O2Ag. Psylla wax ishydrolyzedby alcoholicpotassium hydroxideas well as byhydrobromic acid.[1][2]
Nutritional sources
[edit]Psyllic acid is present inChinese wolfberries.[3][4]
