Abstract:
PURPOSE: A composition for skin external application having antioxidant activity which contains lotus extracts and smoked dry plum extracts is provided to enhance skin erythema prevention, skin tone improvement, and anti-aging. CONSTITUTION: A composition for skin external application having antioxidant activity contains lotus extracts and smoked dry plum extracts as active ingredient. 0.001-10 weight% of the lotus extract is contained based on the total weight of the composition. 0.001-10 weight% of smoked dry plum extract is contained based on the total weight of the composition. The extract is obtained by dipping the raw material into an organic solvent and filtering, reducing pressure and concentrating thereof. The organic solvent is C1-C4 anhydrous or hydrous alcohol, acetone, ethyl acetate, chloroform, glycerine, propylene glycol or butylene glycol. The composition is used for skin erythema prevention or skin tone improvement. The composition is used for skin anti-aging.

Abstract:
PURPOSE: A composition containing plant glycoprotein extract is provided to prevent or treat wrinkle and inflammation and to improve moisturizing and skin regeneration. CONSTITUTION: A composition for preventing or treating skin wrinkle contains 0.1-30 weight% of glycoprotein as an active ingredient, isolated from Bergenia cordifolia, Rhodiola rosea, Comarum palustre, Abies Sibirica, Betula pendula Buds, or Inonotus Obliquus. A method for extracting the glycoprotein comprises: a step of chopping the plants and mixing with organic acid solution of pH 2-3 to obtain an aqueous solution; a step of adding protease and treating at 30-50°C for 2-24 hours; a step of filtering glycoprotein solution and raising temperature to 85°C; a step of continuously heating for predetermined time for sterilization; and a step of centrifuging to remove foreign materials and drying.
Abstract:
본발명에의한인공피부배양용기는한천을이용하되상기한천의일부를소수성으로개질시킴으로써, 인공피부제작과정에서인공피부의진피층에존재하는콜라겐과섬유아세포의상호작용으로인해발생하는진피층의수축및 배양용기로부터의탈착문제해결할수 있다. 이로써상기배양용기를이용하면인공피부를안정적으로배양할수 있고, 인체피부와유사한인공피부를제조할수 있다. 또한, 본발명에의한인공피부배양용기는한천을포함하므로, 배양용기의하부뿐만아니라측면부를통하여도배양액을공급할수 있어, 인공피부를효과적으로배양할수 있다.
