A composition that is useful in a skin function improving agent includes at least a sapogenol, and a collagen hydrolysate. This composition can be used in a skin function improving agent and is particularly useful in a skin function improving agent for inhibiting transdermal moisture loss and/or for retaining the moisture in the stratum corneum.

Composition

A method for enhancing skin collagen in an individual includes administering a composition to the individual, the composition comprising a skin collagen enhancing agent comprising menaquinone-7 as an active ingredient. In addition, a composition is provided in the form of at least one of an emulsion and a cream, the composition including a skin collagen enhancing agent comprising menaquinone-7 as an active ingredient.

Skin collagen enhancing agent

A composition that is useful in a skin function improving agent includes at least two of the following: vitamin K, a sapogenol, and a collagen hydrolysate. This composition can be used in a skin function improving agent and is particularly useful in a skin function improving agent for inhibiting transdermal moisture loss and/or for retaining the moisture in the stratum corneum.

A soy saponin composition is provided high bodily absorption characteristics. In an embodiment, a soyasapogenol composition comprises soyasapogenol B and 3-O-D-glucuronopyranosyl soyasapogenol B. The weight ratio (B/A) of the 3-O-D-glucuronopyranosyl soyasapogenol B to the soyasapogenol B is in the range of 0.001-10. The composition can be produced by partial decomposition of a sugar chain residue of a soy saponin B group glycoside utilizing an acid.

Soyasapogenol composition

Provided is a hyaluronic acid production promoter and a melanin synthesis inhibitor. The hyaluronic acid production promoter and the melanin synthesis inhibitor of the present invention each contain soybean saponin as an active ingredient. The soybean saponin is preferably soybean saponin aglycone. The soybean saponin aglycone preferably includes soyasapogenol A and/or soyasapogenol B. The hyaluronic acid production promoter and the melanin synthesis inhibitor of the present invention are each administered transdermally or orally.

Hyaluronic acid production promoter and melanin production inhibitor

It is intended to provide a method for producing aglycone from a glycoside efficiently at low cost without using an acid catalyst or an organic solvent. The method for producing aglycone, characterized by bringing a glycoside into contact with high temperature high pressure water. The temperature of the high temperature high pressure water is generally from 100 to 374&#xb0; C., preferably from 140 to 320&#xb0; C., more preferably from 200 to 300&#xb0; C. The pressure of the high temperature high pressure water may be not lower than the saturated water vapor pressure at the temperature, i.e., a pressure at which the liquid state is maintained.

Method for producing glycoside aglycone

This invention provides a pharmaceutical and functional food which are made of a safe food ingredient or nutrient which has been used for a long period of time, and which have tranquilizing effect such as anti-anxiety effect, anti-depression effect, and anti-stress effect. The tranquilizer of the invention contains vitamin K as an active ingredient. Vitamin K is preferably menaquinone-4 and/or menaquinone-7. This invention also provides a supplement, health food or functional food for tranquilizing purpose that contains vitamin K as an active ingredient.

Tranquilizer and functional food

The present invention provides a sate and excellent antiallergic composition, and more particularly a preventive and therapeutic composition for atopic dermatitis, including an antiallergic composition blended with stachyose as an effective ingredient, and a medicine, food and beverage containing the composition.
