Heptyl 4-hydroxybenzoate Chemical Properties,Uses,Production

Description

Hesperidin is one of a large group of bio-flavonoids isolated from citrus fruits. Flavonoids comprise a group of naturally occurring compounds which are among the most ubiquitous in the plant kingdom. The basic flavone structure consists of 1,4-benzopyrone with a phenyl substitution in the 2-position. Flavonoids differ in the number and position of substitutions on the aromatic rings and in the extent and character of oxidation in the pryone portion of the molecule. Hydroxyl groups enable flavonoids to combine with sugars to form glycosides, and it is in this form that the flavonoids are usually found in nature. Glucose is the most common prosthetic group, although other sugars, as well as glucuronic and galacturonic acids, have been identified. Hesperetin is the aglycone remaining following hydrolysis from the prosthetic group.
Hesperidin complex is a crude hesperidin preparation obtained by extraction of the albedo of orange peel with calcium hydroxide solution. On acidification with hydrochloric acid to pH about 4.5, hesperidin precipitates as a crystalline material along with other co-precipitated flavonoids. The precipitate is washed to remove non-flavonoid ballast, and then spray dried. Average hesperidin content is 72%; naringenin-7-rutinoside, 4.4%; isosakuranetin- 7-rutinoside, 4.2%; and less than 1% naringenin-7-rutinoside-4’- glucoside, eriocitrin, sinensetin, bobeletin, tangeretin, and several unidentified polymethoxylated flavones. It contains no rutin. The powdered precipitate is nonhygroscopic; its weight loss on drying is 2-5%; sulfated ash, 2-4%; and methoxyl content, 3.3-3.7%.
Purified hesperidin is prepared from hesperidin complex by dissolving the crystals in calcium hydroxide solution and precipitating by acidification with hydrochloric acid. More than one cycle of dissolution and precipitation may be needed to achieve the minimum hesperidin content of 80% specified for the purified product. Most purified product is stated to have a hesperidin content of 90%.
Hesperidin is practically tasteless. Presumably through its action as an antioxidant, hesperidin has been reported to delay flavor deterioration of milk-based beverages, thereby extending shelf life by 6-12 months. Hesperidin also is used as a reagent in the refining and reclaiming of lead and zinc, and as a raw material in the production of the dihydrochalcone of neohesperidin, a nonnutritive sweetener.

Chemical Properties
