Abstract: The invention concerns a process for producing apigenin, wherein it is extracted with a water/ethanol mixture from ligules of Matricaria Chamomilla L. and after purified by crystallization from ethanol.Concerned is also the use of the pure product apigenin in human spasmolytic therapy.

Abstract: Therapeutic compositions for the treatment of acne which comprise from about 0.1% to about 5% by weight naringin, from about 0.1% to about 10% by weight naringenin, from about 0.05% to about 5% by weight of an antimicrobially active partially hydrolyzed naringin, from about 0.01% to about 5% weight colloidal silica, and from about 80% to 97% by weight of a solvent.

Abstract: A process for preparing anthocyans by reducing the corresponding flavonoid glycosides with a metal and acid at temperatures not higher than 30.degree. C. under acidic conditions, precipitating the anthocyans formed from the reduction reaction as a metal salt by neutralizing the reaction solution with an alkali and isolating the free anthocyans by decomposing the metal salt with concentrated hydrochloric acid.

Abstract: A process for the production of antimicrobial compositions from naturally occurring flavanoid glycosides. Flavanoid glycosides are acid hydrolyzed under substantially quiescent condition at a temperature within the range of about 60.degree. C. and about 100.degree. C. for a sufficient time to hydrolyze the flavanoid glycoside to partially hydrolyzed flavanoid compositions having antimicrobial activity.

Abstract: This invention is concerned with a new method of treatment for reducing retention of cholesterol, e.g., in the treatment of atheroma and angiopathies which comprises administering to a patient in need of such treatment, a therapeutically effective amount of at least one anthocyanidin compound of the general formula ##STR1## wherein R represents a glycosyl group such as glycosyl or rhamnoglucosyl; R' represents H, OH or OCH.sub.3 ; and X.sup.- is a non-toxic anion such as chloride, citrate, tartrate, phosphate or malate.

Abstract: Acetals and ketals of benzopyran glycosides, prepared by condensing a benzopyran glycoside with a carbonyl compound using a chloroformate ester as condensing agent, show enhanced activity in treating capillary fragility and related pathologies, as well as effectiveness in modifying the evolution of diabetic cataracts.

Abstract: Glycosides such as stevioside, glycyrrhizin and neohesperidin dihydrochalcone are separated from non-glycosides such as phyllodulcin and perillartine by column chromatography using a porous gel.

Abstract: A process is provided for preparing mono-O-.beta.-hydroxyethyl-7-rutoside of the formula: ##STR1## which comprises contacting rutoside of the formula: ##STR2## in a solvent which is an at least partially aqueous medium with a boric acid alkali salt in an amount substantially not exceeding the amount necessary to form a boron complex of formula: reacting said boron complex with ethylene oxide to form a hydroxyethoxy compound of the formula ##STR3## and treating said hydroxyethoxy compound in an at least partially aqueous acid medium, whereby there is produced said mono-O-.beta.-hydroxyethyl-7-rutoside.

Abstract: Foodstuff and fodder additives are made by linking essential aminoacids to carbohydrates or other assimilable polyhydroxy compounds in such a way that the aminoacid is liberated in the digestive tract.

Abstract: The use of neohesperidin chalcone as a substitute for sugar.

Abstract: A process for manufacturing pure diosmin suitable as a therapeutic agent comprising acetylating hesperidin, observing by means of ultraviolet absorption the progress of the acetylation reaction and continuing such reaction until there disappears the band initially occurring at a wave length in the range of 264 to 280 nm and there appears in place thereof a new maximum at a wave length of about 330 nm. Thereafter the acetylation product is brominated, the obtained bromination product hydrolyzed and the obtained product after precipitation isolated, in order to obtain diosmin having a bromine content less than 0.1%.

Abstract: Dihydrochalcone glucosides are reacted with certain quaternary ammonium compounds to give the corresponding quaternary ammonium derivatives. These new derivatives have a sweet taste and are bactericidal in nature: they can be used in oral products such as dentifrice.

Abstract: New compounds which are monobasic metal salts of dihydrochalcones and the method of their preparation, the monosodium, monopotassium, and monocalcium salts being useful as sugar substitutes and sweetening agents for foods and beverages.
