(-)-Hydroxycitric acid  (Synonyms: Garcinia acid)

(-)-Hydroxycitric acid (Garcinia acid) is the principal acid of fruit rinds of Garcinia cambogia. (-)-Hydroxycitric acid is a potent and competitive and orally active inhibitor of ATP citrate lyase. (-)-Hydroxycitric acid suppresses the fatty acid synthesis, lipogenesis, food intake, and induced weight loss^[1][2].

(-)-Hydroxycitric acid (0-50 µM) reduces lipid droplets accumulation, and decreases ATP-citrate lyase, fatty acid synthase and sterol regulatory element binding protein-1c mRNA level in primary chicken hepatocytes^[4].

(-)-Hydroxycitric acid (1.0 mg/kg embryos, injection) reduces lipid droplets accumulation, triglyceride content, lipogenesis factors mRNA level and increases lipolysis factors mRNA expression in chicken embryos^[3].
(-)-Hydroxycitric acid (p.o., once) shows a LD50 of greater than 5000 mg/kg in fasted male and female Albino rats^[5].
(-)-Hydroxycitric acid (1000-3000 mg/kg diet for 8 weeks) reduces body weight gain, increases feed conversion ratio, and promotes protein synthesis in rats^[6].

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
