Abstract: The present invention provides a highly safe pharmaceutical composition for preventing and/or treating bone disease, a pharmaceutical preparation comprising thereof, a health food comprising thereof, a functional food comprising thereof. Since the present invention comprises the arylheptanoid compound shown in the following formula (I) and the derivatives thereof, it enables to prevent and/or treat the bone disease. (In the formula (I), R1 and R5 are a functional group selected from the group consisting of a hydrogen atom, alkyl group having carbon numbers 1 to 3, monosaccharide and disaccharide; R2, R3, and R4 are a functional group selected from the group consisting of a hydrogen atom, an oxygen atom, alkyl group having carbon numbers 1 to 3, monosaccharide and disaccharide; R5 may be bound on meta-position against heptylene group of another aryl group to form a ring.

Abstract: Agents or pharmaceutical compositions for promoting osteoblast differentiation include purified auraptene or coumarin analogs thereof represented by the following formula 1: wherein R1 represents a hydrogen, a hydroxy, a methoxy, a methyl, an ethyl, a propyl, a carboxyl, a carboxymethyl, or a carboxyethyl; R2 represents a hydrogen, a hydroxy, a methoxy, a methyl, an ethyl, a propyl, a carboxyl, a carboxymethyl, a carboxyethyl or a coumarinyl; R3 represents a hydrogen, a hydroxy, a methoxy, a methyl, an ethyl, a propyl, a carboxyl, a carboxymethyl or a carboxyethyl; and R4 represents a hydrogen, a C1-C15 liner or branched alkyl, an alkenyl, an alkadienyl or an alkatrienyl.

Abstract: Provided is a composition that, even when used in a very small amount, has the effect of improving bone density and promoting bone growth, and has few side effects, and also provided are a pharmaceutical preparation for promoting bone growth, functional food product, and health food product containing the composition as an active ingredient. The composition can be obtained from any plant part selected from the group consisting of the bud, leaf, bark or wood of a plant belonging to the family Magnoliaceae. The composition comprises at least one selected from the group consisting of fargesin and physiologically acceptable salts, hydrates, and glycosides thereof. The pharmaceutical preparation, functional food product, and health food product comprising this composition as an active ingredient sufficiently improve bone density and promote bone growth, even when used in small amounts, and therefore realize preventive and/or therapeutic effects against bone disease etc. such as osteoporosis.

Abstract: A method for screening a substance for treating visceral adiposity syndrome comprises: (1) extracting a total RNA fraction from skeletal muscle collected from non-human mammals of a group to which a predetermined amount of the test substance has been administered and from non-human mammals of a group to which the test substance has not been administered; (2) quantifying the expression quantity of mRNA in the total RNA fraction extracted that encodes a glucose transporter gene by a specific method; and (3) comparing and analyzing the quantity of the test substance ingested, the body weight gain, and the expression quantity of RNA encoding the glucose transporter gene during the administration period for the non-human mammals of the test substance-administered group to these quantities for the non-human mammals that constitute the test substance-unadministered group to thereby determine the effect of the test substance on the metabolic syndrome.
