  • Publication number: 20120165266
    Abstract: Disclosed are the novel glycolipoprotein gintonin isolated and identified from ginseng, a method for preparing the same, and uses thereof. Gintonin causes a transient increase in intracellular free Ca2+ level, which in turn activates endogenous Ca2+-activated chloride channel to elevate intracellular calcium levels. Therefore, the novel glycolipoproteins are useful in the therapy and prophylaxis of calcium deficiency-associated diseases as well as effectively inducing calcium-dependent physiological activities, including adaptogenic activity, immunostimulatory activity, aphrodisiac activity, neuroprotection and neuroactivation, angiogenesis, and antidiabetic activity.
