  • Patent number: 11882858
    Abstract: A skin whitening composition includes ?-mangostin or a cosmetically acceptable salt thereof as an effective ingredient. ?-Mangostin represented by Chemical Formula 1 suppresses the expression of tyrosinase and TRP-1 (tyrosinase-related protein-1) and induces autophagy of a melasosome. As such, it was confirmed that the ?-mangostin not only suppresses melanin production but also exhibits the effect of removing previously formed melanin. Accordingly, the ?-mangostin can be advantageously used as a functional material for skin whitening and skin lightening.

  • Publication number: 20230364170
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating obesity or diabetes, and to a food composition and feed composition for preventing or alleviating obesity or diabetes, comprising as an active ingredient, an Acanthopanax extract, a garcinia cambogia extract, or compounds isolated therefrom. The composition has synergistic antidiabetic and antiobesity activity compared to that of using only an Acanthopanax extract, a garcinia cambogia extract, or compounds isolated therefrom. Therefore, it is possible to reduce the possibility of any side effects that may be caused by an overdose of or long-term administration of the garcinia cambogia extract and a substance isolated therefrom, and thus the composition can be very effectively utilized in the development of a therapeutic agent for diabetes or obesity.
