Abstract: Herbal compositions that comprise one or more of extracts of hydroxycitric acid, (?) HCA and (+) HCA, from Garcinia cambogia and Hibiscus sabdariffa, and anthocyanins from Hibiscus sabdariffa; all constituent extracts at independently controlled concentrations which optionally include second therapeutic agents and pharmaceutically acceptable additives. Processes for the preparation of these herbal compositions, such processes including steps of extracting hydroxycitric acids and anthocyanins from Garcinia and Hibiscus species, reacting the hydroxycitric acid with IA and IIA group metals of periodic table, isolating the metal salt of hydroxycitric acid and drying and optionally mixing anthocyanins.

Abstract: A process of enriching hyroxycitric acid (HCA) from Garcinia rind in which a salt-free water extract of Garcinia rind is loaded onto an anion exchange column, eluted with a metal hydroxide for release of HCA. The water-extract is then treated with a cation exchange column to make free HCA as a free acid. The water extract is loaded at a capacity of 100 to 125% of the anion exchange column and at a capacity of 50 to 90% of the cation exchange column. The HCA can be added to food products such as beverages and snack bars.
