Disclosed is a method for preparing polysaccharides of green tea, and more particularly to a method for preparing polysaccharides of green tea comprising the steps of: a) removing chlorophyll and a low molecular weight polyphenol from green tea powder using a solvent; b) hot-water extracting a water-soluble active ingredient from the green tea residue of step a); and c) separating the polysaccharides of green tea from the hot-water extract of step b) by ultrafiltration and ethanol precipitation. Also, the present invention relates to a cosmetic composition for skin whitening, moisturization and anti-wrinkle effects comprising the polysaccharides of green tea as an effective ingredient.

Method for preparing polysaccharide of green tea and cosmetic composition for skin whitening, moisturization and anti-wrinkle effects comprising the polysaccharide

The present invention relates to a composition for skin external application containing a pine root extract. More specifically, the composition for skin external application according to the present invention contains, as an active ingredient, a pine root extract which shows various effects, including eliminating free radicals, protecting the cell membrane from damage by UV radiation, inhibiting the production of reactive oxygen species caused by UV radiation, inhibiting the reduction in the expression of superoxide dismutase (SOD) and catalase caused by UV radiation, stimulating the production of HSP70 to protect cells, inhibiting MMP-2 biosynthesis caused by UV radiation, inducing the expression of SIRT1 gene that restores DNA damage, and inducing the expression of LMNA1 gene that maintains the structure of the nuclear membrane. Ultimately, the composition of the present invention prevents skin aging.

Method of external skin application of composition containing red pine root extract

Disclosed herein is nanoemulsion prepared by emulsifying main metabolites of ginseng saponin obtained by conversion of glucose, i.e. compound K (20-O-&#x3b2;-D-glucopyranosyl-20(S)-protopanaxadiol), ginsenoside F1 (20-O-&#x3b2;-D-glucopyranosyl-20(S)-protopanaxatriol) and compound Y (20-O-[&#x3b1;-L-arabinopyranosyl(1&#x2192;6)-&#x3b2;-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.
