Synephrine, or, more specifically, p-synephrine, is an alkaloid, occurring naturally in some plants and animals, and also in approved drugs products as its m-substituted analog known as neo-synephrine. p-Synephrine (or formerly Sympatol and oxedrine [BAN]) and m-synephrine are known for their longer acting adrenergic effects compared to norepinephrine. This substance is present at very low concentrations in common foodstuffs such as orange juice and other orange (Citrus species) products, both of the "sweet" and "bitter" variety. The preparations used in traditional Chinese medicine (TCM), also known as Zhi Shi, are the immature and dried whole oranges from Citrus aurantium (Fructus Aurantii Immaturus). Extracts of the same material or purified synephrine are also marketed in the US, sometimes in combination with caffeine, as a weight-loss-promoting dietary supplement for oral consumption. While the traditional preparations have been in use for millennia as a component of TCM-formulas, synephrine itself is not an approved OTC drug. As a pharmaceutical, m-synephrine (phenylephrine) is still used as a sympathomimetic (i.e. for its hypertensive and vasoconstrictor properties), mostly by injection for the treatment of emergencies such as shock, and rarely orally for the treatment of bronchial problems associated with asthma and hay-fever.
Regulation of appetite, body weight and athletic function with materials derived from citrus varieties
Materials derived from Citrus plants can be administered orally to humans for the purpose of producing or maintaining weight loss as well as for improving the person's physical performance and increasing the person's lean muscle mass. The Citrus materials include those portions of the plant that are normally considered waste or inedible, such as the leaves, peel, and immature, unripe fruit. The materials contain at least one of the alkaloids from the group consisting of synephrine, hordenine, octopamine, tyramine and N-methyltyramine (1). Two species, Citrus aurantium and Citrus reticulata, are particularly useful. The materials can be administered in their natural form or as extracts, and can be administered in various ways including capsules and tablets. The Citrus materials may also be used as a tea. For weight loss and weight control, the materials can be administered concurrently with caloric restriction or in the absence of caloric restriction. The materials may also be administered for the purpose of increasing muscle mass concurrently with a high protein diet as well as with an exercise program.

InactiveCN101875703ASuitable for large-scale industrializationReduce manufacturing costOrganic compound preparationAmino-hyroxy compound preparationPectinaseEvaporation
The invention relates to a method for extracting pectin and synephrine by utilizing peels and marc. The pectin comprises three types of protopectin, water soluble pectin and pectic acid, wherein the former is not soluble in water, and the two latter are both soluble in the water. A great number of pectin components and synephrine components exist in the peels and the marc. In the invention, a pectin product is prepared by utilizing a biocatalyst without high temperature and high pressure reaction in the production process, extracting the pectin through effective bonding of acidolysis and enzyme, eliminating the destructive action of pectinase to the pectin through high temperature enzyme killing, releasing the pectin and the synephrine under an acid condition, and extracting and purifying the pectin through a subsequent extraction technology; and a synephrine product is also prepared through resin adsorption, falling film evaporation in waste liquid after the pectin product is prepared.
