摘要:A process of extraction of anthocyanins from different foodstuffs or by-products, and their conversion into pyranoanthocyanins compounds, which can be used as pigments having new colors and improved stability to be incorporated into skincare formulations in particular anti-ageing and sun-protection formulations. Cosmetic formulations having the pigments with improved properties of UV protection and moisturizing, anti-dark spots, anti-wrinkles and wound-healing, which can be associated with interesting colors ranging from red to blue depending on the selected pigments in the composition and in the formula composition. The present invention is in the area of organic chemistry, biochemistry, pharmacology and cosmetics for skincare.

标题:Method for the synthesis of anthocyanins
发明人：BAKSTAD EINAR
权利人:BAKSTAD EINAR; BIOSYNTH AS
摘要:The present invention relates to methods of preparing anthocyanins, and methods of preparing precursors of anthocyanins. The methods utilize a coupling reaction between a sugar and a suitable electrophilic precursor to form Eastern half intermediates that are then reacted with Western half intermediates to form the target anthocyanins. Some Eastern half intermediates and electrophilic precursors also form part of the invention.

摘要:A method for synthesizing a biocompatible, water-soluble oligo/polyflavanoid, includes polymerizing an optionally substituted flavanoid with a polymerization agent in the presence of a biocompatible polymerization solubilizer, thereby producing the biocompatible, soluble oligo/polyflavanoid. Also included is a biocompatible, soluble, oligo/polyflavanoid or a pharmaceutically acceptable salt, solvate, or complex thereof. Also included are methods of treating a subject for cancer, cardiac damage, viral infection, and obesity.
