Abstract: An air conditioner for a vehicle with an improved structure so that hot air is not directly discharged to a defrost vent in a floor mode or a mix mode, includes an air conditioning case in which an air flow path is formed, and a cooling heat exchanger and a heating heat exchanger provided sequentially on the air flow path of the air conditioning case in an airflow direction, wherein a defrost vent, a face vent, and a floor vent are formed on the air conditioning case, wherein the defrost vent includes a first defogging flow path allowing air passing through the heating heat exchanger to be discharged directly, and a second defogging flow path allowing air passing through the cooling heat exchanger or the heating heat exchanger to be mixed and discharged therethrough.

Abstract: Disclosed herein is nanoemulsion prepared by emulsifying main metabolites of ginseng saponin obtained by conversion of glucose, i.e. compound K (20-O-?-D-glucopyranosyl-20(S)-protopanaxadiol), ginsenoside F1 (20-O-?-D-glucopyranosyl-20(S)-protopanaxatriol) and compound Y (20-O-[?-L-arabinopyranosyl(1?6)-?-D-glucopyranosyl]-20(S)-protopanaxadiol); and admixture thereof, in fine emulsion or liposome with dermotropic emulsifier by nano-emulsification; and having enhanced skin penetration, so to be effective in promoting proliferation of fibroblast and biosynthesis of collagen.

Abstract: There are provided a promoter containing ginsenoside compound K for the production of hyaluronic acid, and more particularly, a new efficacy of 20-O-?-D-glucopyranosyl-20(S)-protopanaxadiol (compound K), a chief metabolite of ginseng saponin, to increase the expression of hyaluronic acid synthase gene in human cell and thereby to promote the production of hyaluronic acid, and an anti-aging agent containing the promoter for the production of hyaluronic acid as an effective ingredient.
