Abstract: The present invention provides S-(?)-tulipalin B, acetylated-S-(?)-tulipalin B and an antibacterial composition comprising the same. The active compound tulipalin B and composition of the present invention exhibit superior and stable antibacterial activity over a broad range of temperature and pH, as compared to conventional natural antibacterial agents used in related industries. Therefore, the composition and active compound of the present invention can be widely used as a natural food preservative and/or an antibacterial agent in a variety of fields such as foods, pharmaceuticals, cosmetics, fibers, livingwares, and the like.

Abstract: Disclosed is a composition for improving atopic dermatological diseases comprising magnolol, honokiol or the combination thereof.

Abstract: Disclosed herein is a natural composite preservative comprising extracts from Camellia sinensis, Matricaria recutita, Citrus grandis, Magnolia biondii, propolis, Thujopsis dolabrata and Salix alba, in combination. The natural composite preservative has potent antibacterial activity against a wide spectrum of microorganisms in addition to being safe for the body, producing neither toxicity nor irritation, and thus can be applied to cosmetics, pharmaceuticals, and foods.

Abstract: The present invention relates to a method for economically preparing ginseng extract having an increased content of physiologically active substances, comprising the steps of steaming ginseng at 95 to 100° C. for 1 to 24 hours, collecting the generated vapor by cooling, and repeating the process twice, to a composition for promoting collagen synthesis, comprising the extract, and to a cosmetic product for improving skin wrinkles, comprising the composition.

Abstract: Disclosed are multilayered liposomes for transdermal absorption and a method of preparing the liposomes. The multilayered liposomes are prepared using a mixture of oil-phase components comprising squalane, sterols, ceramides, neutral lipids or oils, fatty acids and lecithins, is 200 to 5000 nm in particle size, and is capable of entrapping a physiologically active substance. The multilayered liposomes entrap a larger amount of a physiologically active substance and are structurally stable when encapsulating the physiologically active substance, compared to unilamellar liposomes. Also, they are prepared by a simple and cost-effective process not using a high-pressure homogenizer but using a general homo mixer.

Abstract: The present invention relates to skin whitening and/or depigmenting composition containing arbutin and glucosidase as active ingredients. The glucosidase is an enzyme hydrolyzing arbutin into hydroquinone and glucose.

Abstract: The oral vaccine of the present invention containing the HPV like particles is produced in edible transgenic plants and then administered through the consumption of the edible portion of those plants or after the purification of the particles. A DNA sequence encoding one of the HPV capsid proteins is isolated, inserted into the plasmid which comprises a plant-specific promoter and a gene for a selection marker, and then transferred to plant cells to give transgenic plants. Since the gene is expressed in a portion of the plants, the oral vaccine of the present invention can be produced in an inexpensive manner and administered in a simple method.
