96 results about "Synephrine" patented technology

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.

Method for extracting synephrine and hesperidin from citrus aurantium

The invention discloses a method for extracting synephrine and hesperidin from citrus aurantium, and relates to a method for producing and processing traditional Chinese medicine. The method comprises the following steps of: step 1, washing and crushing a citrus aurantium raw material into citrus aurantium granules; adding an acid solution for soaking the citrus aurantium granules, then carrying out percolation and extracting extract, concentrating the extract under the reduced pressure to obtain extractum, and drying the extractum under the reduced pressure to obtain synephrine; step 2, adding a weak base solution into the leached citrus aurantium granules which are extracted after being soaked by the acid solution, carrying out decoction and removing impurities, then adding a mixed solvent of sodium hydroxide and calcium chloride into the citrus aurantium granules, and extracting to obtain extract; step 3, adding hydrochloric acid into the extract for neutralization until the pH value is 3-7, standing still and crystallizating; and step 4, collecting crystalline, and drying to obtain the hesperidin. Compared with the prior art, the method can be used for extracting two components without using an organic solvent, so that the production cost is reduced, the production technology is simplified, the synephrine yield is more than 15%, the content of the synephrine is more than 10%, the hesperidin yield reaches more than 27%, and the content of the hesperidin is more than 96%; and therefore, the method is suitable for industrialized mass production.
