  • Patent number: 8168237
    Abstract: Disclosed is an anti-obesity active extract obtained from a medicinal plant. More specifically, the extract obtained from lysimachiae foenum-graeci herba (which is a medicinal plant traditionally used in the East) can be used as an active ingredient for a raw material, a functional food, cosmetic, a crude drug, etc. for an obesity preventing or therapeutic agent because the extract can suppress the adipocyte differentiation and decrease the body weight and body fat in an obese animal, thereby suppressing fat accumulation (that is, a factor for obesity).

  • Publication number: 20120065272
    Abstract: The present invention relates to a new use of panduratin derivatives or a Kaempferia pandurata extract comprising the same. More particularly, the present invention relates to a composition for improving wrinkles and/or preventing aging, which comprises a panduratin derivative or a Kaempferia pandurata extract comprising the same. The said the panduratin derivative or the Kaempferia pandurata extract comprising the same induces cell proliferation, inhibits degradation of collagen, and promotes synthesis of collagen, therefore, it shows excellent activity in prevention of aging, particularly preventing, improving or treating wrinkle and it can be used as an effective ingredient in a cosmetic, food or pharmaceutical composition.
