Abstract: The present invention provides a method of obtaining Psidium guajava leaf extract standardized to phytochemicals. The extract obtained is highly soluble in water, and contains standardized phytochemicals such as, guijavarin specifically saponins and polyphenols, which may be used in food and beverage products. The method involves the specific method of filtration to obtain highly purified form of phytochemical. The extract obtained is subjected to bio-activity guided fractionation to isolate different compounds to obtain phytochemical enriched fraction followed by purification and isolation of the single phytochemical from the enriched bioactive fraction. The phytochemical is identified as guijaverin, which also exhibits anti-diabetic activity. The Psidium guajava leaf extract is useful in food and beverage industries and is used in different formulations such as chocolates, capsules, and aqua based supplement drinks.

Abstract: The present invention discloses a slim and aqueous extract of Garcinia cambogia comprising (?)-hydroxycitric acid as dietary product for weight management. The present invention also discloses a process of preparation of aqueous extract wherein the Garcinia cambogia fruit rinds are subjected to cold circulation to retain the phytochemical components and the aqueous extract is adjusted to neutral pH and stabilized with triple mineral salt of calcium, magnesium and potassium and decolorized using activated carbon. The colorless, odorless aqueous extract obtained is subjected to qualitative and quantitative analysis to obtain pure concentrate, which is useful in food, beverage and pharmaceutical industries as dietary supplement. The concentrate equivalent to 1500 mg of (?)-hydroxycitric acid on dried basis is used for the consumption with the distilled water. The slim and aqueous extract concentrate of Garcinia cambogia is useful in treatment of overweight, obesity and hypercholesterolemia.
