it has now been discovered that the association of phaseolus vulgaris extract with a standardised phaseolamin content and alpinia officinarum extract with a standardised 3 - methylethergalangin content is particularly effective for the prevention and treatment of obesity and type ii diabetes . this invention consequently relates to compositions containing phaseolus vulgaris extract with a standardised phaseolamin content and alpinia officinarum extract with a standardised 3 - methylethergalangin content for the prevention and treatment of obesity and type ii diabetes . more particularly , the compositions according to the invention contain phaseolamin and 3 - methylethergalangin in the ratio of 1 : 5 . the compositions to which this invention relates are in gastroprotected form , to prevent the breakdown of phaseolamin on contact with the gastric juices and to guarantee the stability of 3 - methylethergalangin even at a ph of 1 . according to a preferred aspect , the compositions according to the invention will contain alpinia officinarum extract in ethyl acetate , with a standardised 3 - methylethergalangin content . according to a preferred aspect , the compositions according to the invention will contain indena phaseolamin standardised from 5 to 18 % ( with a phytohaemagglutinin content of between 0 . 01 and 0 . 06 %). this phaseolamin will be gastroprotected according to the process described in italian patent application no . mi2004a000313 . the phaseolamin content of the compositions according to the invention will range between approx . 0 . 1 and approx . 1000 mg , preferably between 2 and 10 mg . the 3 - methylgalangin content of the compositions according to the invention will range between approx . 0 . 1 and approx . 500 mg , preferably between 1 and 100 mg . the compositions according to the invention cause a reduction in the blood glucose peak and the postprandial lipid peak greater than that generated by the sum of the effects obtained after separate administration of the individual constituents of the association , apparently due to synergy between the individual constituents . the compositions according to the invention will preferably be taken a few minutes before meals , to ensure that the product arrives when pancreatic secretion has begun and just before emptying of the stomach , with arrival of the food at the same level . this administration will reduce the absorption of free sugar , lipids and triglycerides , with a consequent calorie reduction and a reduced risk of obesity and diabetes . the compositions according to the invention could be formulated suitably for oral administration , and will be prepared according to conventional methods well known in pharmaceutical technology , such as those described in remington &# 39 ; s pharmaceutical handbook , mack publishing co ., n . y ., usa , using excipients , diluents , fillers and anti - caking agents acceptable for their final use . examples of formulations according to the invention are set out below .
a process for treating an individual suffering from obesity and type ii diabetes in which said individual is caused to ingest a composition comprising a kidney bean extract with a standarized phaseolamine content and alpinia officinarum extract with a standardized 3 - methylethergalangin .
