Beschreibung
Magnolol is derived from the root bark and branch bark of magnolia or Magnolia
officinalis. Magnolia officinalis was first written in the《ben jing》, it prefers cool
and humid climate and well-drained acid soil. Cortex magnoliae officinalis (hou po)
is mainly produced in Sichuan (Wan quan, Shizhu, Guanxian), Hubei (Shien,Yichang,
Lichuan), Zhejiang (Longquan, Anhui), and other places. It is also distributed in
Fujian, Jiangxi, Hunan, Guangxi, Yunnan, Guizhou, Shanxi, Gansu, and other places.
Cortex magnoliae officinalis from Sichuan and Hubei is called “chuan pu,” with better
quality, while in Zhejiang, it is called “warm park,” with a larger output.
Physikalische Eigenschaften
Appearance: white fine powder. Solubility: practically insoluble in water; very soluble
in benzene, ethyl ether, chloroform, and acetone. Melting point: magnolol is
102 °C. Honokiol is 87.5 °C.
History
In 1930, magnolol was first isolated from the bark of Cortex magnoliae officinalis
in China by Japanese Sugii, and it was also isolated from Cortex magnoliae officinalis
in Japan. In 1973, magnolol and its isomers honokiol were isolated from Cortex magnoliae officinalis in China and Japan by Japanese Fujita.
The drug research and development of magnolol and honokiol remain in pharmacological activity and preclinical research. Kyung Hee University from Korea declared a preclinical study in 2003, in which allergy, anxiety, angina, and heart failure are indications for honokiol.
Verwenden
Honokiol is a small-molecule polyphenol isolated from the genus Magnolia. Recent studies show that Honokiol displays antiangiogenic, antiinflammatory, and antitumor properties in preclinical models, w
ithout appreciable toxicity. Honokiol has been shown to inhibit the bone metastatic growth of human prostate cancer cells.
Indications
These compounds are recorded in the British Pharmacopoeia (2017) and European
Pharmacopoeia (8.7th ed.). They are mainly used as antibacterial and antifungal
agents.
Allgemeine Beschreibung
Honokiol exhibits analgesic, antithrombotic, antispasmodic, antidepressant, antimicrobial and neuroprotective effects. It regulates gamma-aminobutyric acid (GABA) A receptors. Honokiol is associated with an increased risk of bleeding. It prevents platelet aggregation, protects myocardium from ischemic damage and inhibits ventricular arrhythmia.
Pharmakologie
Magnolol and honokiol have the pharmacological effects of prolonging central
muscle relaxation, inhibition of the central nervous, anti-inflammatory, antibacterial,
