How Many Chemical Compositions Does Citrus Aurantium Extract Have?

- Feb 25, 2020-

The main components of citrus aurantium extract are dextrin and citral, which can be used as food and cosmetic perfumes. The main component of orange pigment is carotenoid, an important natural food coloring. Hesperidin is a rutin of hesperidin, which has the effects of maintaining normal osmotic pressure of blood vessels, reducing vascular fragility, and shortening bleeding time. Orange peel has a high content of flavonoids, such as hesperidin, neohesperidin, hesperetin, Chuanchensudin, dihydrochuan, Chenpi, etc. The flavonoids contained in citrus have antibacterial, anti-inflammatory, anti-allergic, analgesic effects, prevent and cure cardiovascular diseases, anti-viral, anti-oxidant, anti-cancer effects, and can be used for pharmaceuticals. Orange peel flavonoids can also be used as food additives.

Citrus Aurantium Extract

can extract antioxidants, orange pigments, pectin, essential oils, and produce deep-processed products such as organic fertilizers, biogas, or water treatment adsorbents. It is very useful for improving the economic efficiency of citrus processing plants, reducing pollution and protecting the environment. advantageous. Especially with the development and research of functional polysaccharides, pectin. Citrus aurantium extract as a water-soluble dietary fiber, has received more and more attention from the research and processing industry.


Overview of research on chemical composition about citrus aurantium extract

◆ Flavonoids

 Citrus contains flavonoids such as flavanone, flavonoid, and flavonol, among which flavanone is the most abundant. 85 compounds were isolated from citrus peels, of which 38 were new compounds, most of which were glycoside compounds, such as flavonoid glycosides, limonoid glycosides, phenylpropanoid glycosides, terpenoid glycosides, and hydrocarbyl glycosides. Several novel cyclic peptide compounds and nitrogen-containing compounds alkaloids were presented.

◆ Pigment

 As a food additive, food coloring is widely used in food production. Rosenberg extracted carotenoids from citrus peel with d-lemon olein, and Li Youzheng and others found that the main component of orange pigment was carotenoids.

◆ Essential oils

The essential oils are extracted by cold pressing, distillation, extraction, etc. The most commonly used method is steam distillation. Extraction of citrus essential oil by supercritical method using CO2 as solvent. After analysis, many extracted ingredients are mainly oxidized compounds-terpenes, lemon olein, linalool, and taroene is the most important component in the extract.

◆ Hesperidin

Researchers have extracted several pigments and hesperidin from citrus aurantium. They treated the orange peel with supercritical carbon dioxide, separated the essential oil of orange peel, and extracted hesperidin with solvent.

◆ Pectin

Researchers used microwave pretreatment to extract pectin. They used hydrochloric acid extraction and ethanol precipitation to extract pectin from orange peel, and then extracted orange yellow pigment and hesperidin from citrus peel by leaching and alkali dissolving, and then extracted pectin by mixed salting.
