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.

The present invention relates to pharmaceutically active extracts of Vitex leucoxylon exhibiting hypoglycemic and anti-inflammatory properties. This extract is suitable for administrating to animals and humans in treating diabetes, liver disorders and related inflammatory diseases. The extract is found suitable for treating insulin and non-insulin diabetes mellitus.
摘要:
A process for producing an enriched fraction of tetrahydoxycurcumin containing, tetrahydroxycurcumin, demethylcurcumin, demethylmonodemethoxycurcumin and bisd.emethoxycurcumin and colorless tetrahydroderivatives thereof. The process consists of demethylation of natural curcumins, obtained, in turn, from the organic solvent extract of turmeric from Curcuma species. The said enriched fraction of tetrahydroxycurcumin is subjected to hydrogenation to get colorless tetrahydrotetrahydroxycurcumin enriched fraction. The enriched fractions of tetrahydroxycurcumin and colorless tetrahydrotetrahydroxycurcumin exhibits potent antioxidative action and reduces inflammation.
摘要:
This invention relates to new double salts of (−)-hydroxycitric acid with group II metals. Preferred double salts are calcium and magnesium double salts of hydroxycitric acid of the formula II. This invention also includes a process for the preparation of these double salts by the addition of one metal compound from group II to (−)-hydroxycitric acid solution followed by the addition of other metal compound solution from group II. These double salts are tasteless and are soluble in water. They are useful as dietary supplements and in beverages.

摘要:
This invention relates to a novel process for preparing highly water soluble alkaline earth metal and alkali metal double salts of hydroxycitric acid. These salts are practically odourless and has negligible taste and are therefor useful as nutraceuticals. Aqueous extract of the fruits belonging to Garcinia species are treated to precipitate its alkaline earth metal salts such as the calcium salt. This sparingly soluble product is dissolved in alkali hydroxide and the pH of the solution is adjusted by adding purified extract of the fruit rind. Ca/Na or Ca/K double salts are particularly useful.

摘要:
This invention relates to novel polyhydroxy curcumins of the formula (I), wherein R and R1 may be same or different and are selected from H, OH and OCH3. This invention also includes a process for synthesising the above polyhydroxy curcumins by reacting substituted aromatic alhehydes with a diketone in the presence of boron oxide, alkyl borate and a primary or secondary amine catalyst. If desired, the resulting compounds can be deprotected by known means. These compounds are used as anti-oxidants.
