    摘要: This invention relates to novel triple salts of (−)-hydroxycitric acid having the general formula 1 wherein X, Y are selected from zinc or group IIA metal and Z is selected from group IA metal of the Periodic Table. Preferred salts are triple metal salts of calcium, magnesium or zinc and potassium.This invention also includes a process for preparing the triple salts by adding stiochiometric amounts of aqueous solutions of the compounds of the desired metal to an aqueous solution of (−)-HCA. Preferably an extract from garcinia fruit ring is used as a starting material.Compounds of this invention are substantially tastless, odorless and highly water soluble and find use in beverages and in neutraceuticals.
