Quantity: 1000 MonthlyKilograms Specs:30% Payment Method: T/T, L/C Allium Cepa Extract Synonyms: Bulb Onion Extract; Common Onion Extract; Garden Onion Extract Botany: Onion is a term used for many plants in the genus Allium. They are known by the common name "onion" but, used without qualifiers, it usually refers to Allium cepa. The onion (Allium cepa) is the most widely cultivated species of the genus Allium. The genus Allium also contains a number of other species variously referred to as onions and cultivated for food, such as the Japanese bunching onion, Egyptian onion, and Canada onion. The name "wild onion" is applied to a number of Allium species. Kingherbs use the red onion for extraction, which contains the highest spiraeoside. Active Ingredient: In onion, spiraeoside (quercetin-4′-O-β-D-glucoside), rutin and quercetin and 3 other not identified compounds were found as the major constituents. Significant cultivar differences were found. The most abundant compound was spiraeoside (32 234 mg/kg DM in red onion, 23 283 mg/kg DM in yellow onion and 265 mg/kg DM in white onion). Spiraeoside: Synonym(s): Quercetin 4'-glucoside; Spiraein. CAS: 20229-56-5. Molecular Formula: C21H20O12. Molecular Weight: 464.382. Useful Part: Bulb. Appearance: Yellowish brown powder. Test Method: UV. Function: 1. Anti-cancer effect; 2. Lower blood pressure, prevent blood clots; 3. Lowering blood sugar, blood fat; 4. Antibacterial; 5. Antioxidant properties related to health effects. Total polyphenol and main flavonoid antioxidants in different onion (Allium cepa L.) varieties. In onion, spiraeoside (quercetin-4′-O-β-D-glucoside), rutin and quercetin and 3 other not identified compounds were found as the major constituents. Significant cultivar differences were found. The most abundant compound was spiraeoside (32 234 mg/kg DM in red onion, 23 283 mg/kg DM in yellow onion and 265 mg/kg DM in white onion). During storage, an increase in flavonoids could be observed, especially at a laboratory temperature compared to storage at a lower temperature. We use the red onion for extraction, which contains the highest spiraeoside. |
