Magnolol - Reference Information
| Plant source: | Magnolia officinalis |
| FEMA | 4559 | MAGNOLOL |
| plant extract | magnolol is officinalis Rehd. et Wills from Magnoliaceae (Magnoliaceae) plant Magnolia Magnolia. And Magnolia officinalis Rehd. et Wills. var. biloba Rehd. et Wills. An active substance extracted from dry skin, branch skin and root skin has antibacterial, anti-inflammatory, anti-tumor, anti-endomycin, muscle relaxation, and relief of acute inflammatory pain. In terms of antibacterial effect, magnolol has significant antibacterial activity against Gram-positive bacteria, acid-resistant bacteria and filamentous fungi, has more significant antibacterial effect against Streptococcus mutans, and has the strongest inhibitory effect on Staphylococcus. Clinically, it is mainly used to eliminate chest and abdomen fullness, calm the central nervous system, athlete muscle relaxation, antifungal, anti-ulcer and other drugs. [Habitat and Distribution] It often grows in the foothills of hillsides at an altitude of 800~1700 meters and in the mixed woods beside streams. It is a light-loving native tree species; it likes cool and humid climate. Slightly acidic or neutral soil with deep, fertile, loose, humus-rich and well-drained soil is appropriate. Mainly produced in Enshi, Jianshi, Badong, Yichang, Lichuan in Hubei Province and Chengkou, Kaixian, Wuxi, Wushan, Shizhu, Wulong, Fengjie in Chongqing. Chongqing Yunyang, Wanzhou, Zhongxian, Fengdu, Fuling, Jiangjin, Qianjiang, Pengshui, Xiushan, Nanchuan and other places are also distributed. [plant morphology] deciduous trees, 7~15m high. The bark is purple-brown, the winter buds are covered by stipules, and the stipules fall off after opening. Single leaves alternate, gathered at the top of branchlets, the leaves are elliptic and obovate, 20 ~ 45cm long, 10 ~ 25cm wide, the apex is obtuse or short-pointed, the base is cuneate or round, the entire or microwave-shaped, and the back When young, it is gray-white and short tomentose, and when old, it is white and powdery. Flowers and leaves open at the same time, single branch tops, white, fragrant, about 15cm in diameter, stout pedicel, covered with brown hairs; tepals 9~12; many stamens; pistil carpels many, arranged on the extended torus. Aggregate fruit ovate-elliptic, woody, with 1 seed per chamber. The flowering period is from April to May and the fruiting period is from September to October. Figure 1 is Magnolia officinalis |
| application | Magnolia officinalis total phenol is a phenolic mixture extracted from traditional Chinese medicine Magnolia officinalis, which has many biological functions such as antiviral, antibacterial, anti-inflammatory and anti-diarrhea, while the antioxidant effect of Magnolia officinalis total phenol is an important basis for its biological function. |
| pharmacological action | magnolol is a diphenylpropyl compound, white to yellowish brown powder, fragrant, spicy and slightly bitter. it is the main active ingredient of magnolia officinalis, and is a small molecular natural product extracted from dry dry skin, root skin and branch skin of magnolia officinalis or magnolia officinalis of magnolia family, it has the effects of anti-inflammatory, antibacterial, protecting cardiovascular and cerebrovascular system, anti-anxiety and depression, muscle relaxation, anti-oxidation, improving gastrointestinal dysfunction and anti-tumor. The water extract of Magnolia officinalis has a significant arrow poison-like effect. Its alcohol extract can reduce the grip strength and has a strong inhibitory effect on spasms induced by drugs such as strychnine and diprotoxin. It can relieve the intestinal spasm caused by barium chloride and pilocarpine, and has an inhibitory effect on the contraction of isolated guinea pig bronchial smooth muscle caused by histamine. A water-soluble alkaloid was isolated from Magnolia officinalis-Magnolia officinalis (also known as Magnolia curarine) has a relaxing effect on striated muscle and can block the transmission of impulses on the motor endplate, so it is a nerve-muscle block effect. honokiol has antibacterial effects on gram-positive bacteria such as staphylococcus, pneumococcus, hemolytic streptococcus and gram-negative bacilli such as dysentery bacillus, typhoid bacillus, Escherichia coli and Bacillus subtilis. The ether extract of Magnolia officinalis can reduce the spontaneous activity of mice and resist the excitement caused by methamphetamine or apomorphine. Magnolol and isobalokiol also have significant central inhibitory effects. Magnolol can completely inhibit spinal cord reflex in mice, and ether extract 0.25~1 g/kg can show central inhibition that any reflex disappears. Magnolia officinalis Shengpin and Jiang Zhipin have anti-gastric ulcer effect on rat pyloric ligation type and stress type 2 acute experimental gastric ulcer model, especially ginger products have stronger effect. With magnolol 100mg/kg intraperitoneal injection or subcutaneous injection, water immersion bound stress ulcer disease, mercaptoethylamine ulcer, pyloric ligation ulcer have inhibitory effect, but also can antagonize the role of central gastric acid secretion stimulant. |
| use | used for content determination/identification/pharmacological experiments, etc. Pharmacological effects: Magnolol has obvious and long-lasting central muscle relaxation, central nervous system inhibition, anti-inflammatory, antibacterial, anti-pathogenic microorganisms, anti-ulcer, anti-oxidation, anti-tumor, inhibit morphine withdrawal reaction, can inhibit Platelet aggregation and other pharmacological effects, magnolol is used to treat acute enteritis. Bacterial or amoebic dysentery. Chronic gastritis, etc. Among them, in terms of antibacterial effect, magnolol has significant antibacterial activity against Gram-positive bacteria, acid-resistant bacteria and filamentous fungi, has more significant antibacterial effect against Streptococcus mutans, and has the strongest inhibitory effect on Staphylococcus. Clinically, it is mainly used to eliminate chest and abdomen fullness, calm the central nervous system, athlete muscle relaxation, antifungal, anti-ulcer and other drugs. It has antifungal, antibacterial and antioxidant bioactive substances, and has anti-inflammatory activity by interfering with NF -κB signaling. |
