Abstract:
Provided is a pressure-cycling type of extraction device comprising: an extraction unit for accommodating and extracting an extraction target substance; a compression unit for increasing the pressure inside the extraction unit; and a decompression unit for decreasing the pressure inside the extraction unit; wherein the pressure inside the extraction unit is increased and decreased by alternately operating the compression unit and the decompression unit, and the extraction unit comprises a bubbling nozzle for supplying bubbles into the extraction target substance. Further provided is a pressure-cycling type of extraction method in which a compression process and a decompression process are carried out alternately, and compositions produced by the method. The extraction device and method allow low temperature extraction, permit outstanding extraction efficiency and can prevent colour changes, olfactory changes and thermal denaturation of the extraction target substance.
Abstract:
The present invention relates to a cosmetic cotton-like material having excellent air permeability that is prepared from the paper mulberry by removing fiber-binding substances such as pectin and lignin from the paper mulberry fiber, a preparation method thereof and a mask pack comprising the cotton-like material.
Abstract:
Disclosed herein are a method for quantifying skin changes caused by six external evils and a method of screening skin condition-improving materials using the quantification method. More specifically, disclosed are a method of measuring cellular changes caused by external stimuli in a skin cell culture system, in which the degree of cellular changes obtained by applying suitable stimuli of six external evils to skin cells being cultured is measured by cellular biochemical methods, such that the conceptual effects of six external evils suggested in the prior art can be scientifically and quantitatively expressed, and a method of screening skin condition-improving materials using the measurement method.
Abstract:
Disclosed is a composition for external skin application for preventing skin aging comprising pine knot extract as an effective ingredient. The composition prevents and improves winkles through of skin cell proliferation and collagen biosynthesis, and may be widely applied in the field of skin beauty care and cosmetics.
Abstract:
The present invention relates to an agent for controlling Bcl-2 expression comprising ginsenoside F1 (20-O-beta-D-glucopyranosyl-20(S)- protopanaxatriol) represented by the following formula 1 as an active component. [Formula 1]
Abstract:
The present invention relates to the novel Rhizobium sp. GIN611 KCTC11708BP or to cell extracts thereof, to a novel oxidoreductase which exhibits a glycolytic activity, to a gene encoding the oxidoreductase, to a recombinant strain comprising recombinant vector proteins or to an expression vector encoding recombinant proteins, and to a method for the glycolysis of natural products using same as a biocatalyst. The present invention also relates to a method for producing aglycones from a variety of natural products using same. The novel oxidoreductase separated from the novel microorganism of the present invention does not belong to a glucosidase group but belongs to an oxidoreductase group, and has a glycolytic activity for natural products. The novel oxidoreductase oxidizes the sugar in the aglycones of natural products, thereby producing a variety of aglycones.
Abstract:
Disclosed is a hydroxybenzamide derivative represented by the following Formula (1). A method for preparing the same and a cosmetic composition comprising the same are also disclosed. More particularly, the hydroxybenzamide derivative is obtained by reacting a hydroxybenzoic acid having a protecting group introduced thereto with a hydroxyphenyl amine to form a benzamide derivative and by hydrolyzing the benzamide derivative in an aqueous base solution to form a hydroxybenzamide derivative. The cosmetic composition comprising the hydroxybenzamide derivative as an active ingredient has excellent anti-oxidative, anti-aging and skin wrinkle- alleviating effects. wherein R1 represents a C1 ~ C10 alkyl group, and n is an integer ranging from 1 to 3.
