What is Pure Honokiol?

Pure Honokiol is an isomer of magnolol, which is a dimer developed by the polymerization of the side chain of one phenylpropanoid as well as the benzene center of one more phenylpropanoid. It is called neolignan as well as is discovered in Lauraceae. It is the active component of Chinese medicine Magnolia officinalis, which is antibacterial as well as anti-inflammatory.
Pure Honokiol, a biphenolic substance, is among the main active components of Magnolia officinalis. The energetic ingredients of Magnolia officinalis are mostly phenolic substances (mostly magnolol and Pure Honokiol) drawn out from the origin bark and branch bark of Magnolia officinalis. The sloping area with an altitude of 800-1700m comes from the uncommon as well as endangered medicinal plants under the second-class nationwide security. According to medical records, Magnolia officinalis has the features of heating the center, advertising qi, drying wetness as well as removing phlegm.
International modern pharmacological tests have actually confirmed that honokiol has broad-spectrum antibacterial homes, has a special and long lasting relaxation impact on muscular tissues, and also has significant central restraint and anti-ulcer and anti-gastric acid secretion impacts, so it can be utilized for anti-bacterial, anti-ulcer, sedative Central nerve system, unwind muscular tissues. In the therapy of intestinal illness, Pure Honokiol additionally has a really high professional value.

Pharmacology of Pure Honokiol

1. Anti-pathogenic microorganisms Magnolia decoction is effective against gram-positive bacteria such as Staphylococcus, hemolytic streptococcus, pneumococcus, bacillus pertussis, as well as bacillus anthracis, dysentery bacillus, typhoid bacillus, paratyphoid bacillus, vibrio cholerae , Escherichia coli, Proteus, Bacillus subtilis, Bacillus diphtheria and other Gram-negative bacteria have inhibitory effects, of which the inhibitory effect on Staphylococcus is the strongest. At a concentration of 15%, it has inhibitory effects on dermatophytes such as Bacillus microsporum, Trichophyton concentric, Trichophyton rubrum, and Trichophyton versicolor in experimental animals. Magnolia decoction has some effect on improving the substantive pathological damage of experimental viral hepatitis in mice. Honokiol has considerable antibacterial activity against Gram-positive germs and also acid-resistant bacteria; Pure Honokiol has an extremely substantial anti-caries result, with a minimum repressive concentration of 6.3 μg/ ml, and also its antibacterial task is stronger than that of the normal anti-bacterial alkaloid Berberis Base (MIC: 50 μg/ ml). Magnolia and also Magnolia volatile oil saturated aqueous option have particular antibacterial impacts on Staphylococcus aureus, Sarcinus and also Bacillus subtilis.

2. Impacts on the cardiovascular system Honokiol and Pure Honokiol inhibit the formation of thromboxane B2 under numerous problems, as well as the increase in intracellular Ca2+ brought on by arachidonic acid or collagen is additionally prevented by both. Pure Honokiol can hinder the task of CaM-stimulated cyclic nucleotide phosphodiesterase, and also honokiol can bind to webcam in the existence of Ca2+, thereby annoying its activation of phosphodiesterase. Furthermore, Pure Honokiol has a stimulating impact on the basal activity of CaM-dependent phosphodiesterase.

3. Anti-tumor effect Honokiol and its hydroxymethyl derivatives have obvious inhibitory effect on secondary skin tumors in mice. The three extract components of Magnolia officinalis, lignan, honokiol, Pure Honokiol and the monoterpene magnoliol, are 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced Epstein-Barr Antagonist of viral early antigen (EBv-EA) activation. Pure Honokiol, a methanol extract of Magnolia officinalis, has a significant inhibitory effect on mouse skin tumors induced by a phase II carcinogenic experiment in vivo.

Preparation method of Pure Honokiol

The first step: take 14.80 g of 4-allyl anisole into a 250 ml flask, slowly add an appropriate amount of pyridine perbromide as a brominating agent, add an appropriate amount of Zn as a catalyst, and react for 3 h. The fraction at 152°C was distilled off under reduced pressure, which was 2-bromo-4-allyl anisole.

The second step: take 18.70 g of 4-bromo-anisole, add ethyl magnesium chloride, 2,5-dimethylphenyl magnesium bromide, react at 40 ° C for 2 h, and then slowly add 12.10 g of allyl bromide, After the reaction for 5h, the fraction at 150°C was distilled off under reduced pressure, which was 4-bromo-2-allyl anisole.

The third step: Dissolve 2.38 g of nickel hexahydrate in 2 ml of water, add 5.25 g of triphenylphosphine, dissolve in 75 ml of glacial acetic acid, and react at room temperature for 24 h. Olive green microcrystals are precipitated in the reaction solution. Filter, wash with glacial acetic acid, and dry in a desiccator with sulfuric acid or potassium hydroxide in a vacuum to obtain dark blue crystals.

The fourth step: take 150 ml of anhydrous ether into a 250 ml flask, add 3.00 g of magnesium strips, soak for 1 h, and then slowly add the prepared 4-bromo-2-allyl anisole, reaction 3 h, make 4-bromo-2-allyl anisole into Grignard reagent, then add the prepared 2-bromo-4-allyl anisole into it, react for 12 h, distill out under reduced pressure Fractions below 150°C are obtained to obtain Pure Honokiol methyl ether, which is then hydrolyzed, finally extracted with ethyl acetate and water, concentrated to dryness under reduced pressure, and purified by silica gel column chromatography (ether:hexane=1:2) to obtain white crystals The product is Pure Honokiol.

Pure Honokiol Extraction Method

1. The manufacturing procedure of Magnolia officinalis essence (liquid remove) is to crush Magnolia officinalis, soak with ethanol for 12 hours, place it in a percolation cyndrical tube, penetrate with about 12 times the quantity of ethanol, accumulate the percolation liquid, and recuperate ethanol under decreased stress to the fullest., need to flow remove. The yield is about 9%, the strong content is 85.0%, the material of magnolol is more than 11.0%, and also the material of Pure Honokiol is more than 5.0%.

2. Extraction and splitting up of magnolol and Pure Honokiol Take the crude powder of Magnolia officinalis, include 1/5 amount (W/W) of quicklime powder, mix well, and infiltrate with 15-20 times the amount of pure water. Include hydrochloric acid to readjust the pH to 2-3, as well as allow it stand. Collect the precipitated precipitate, wash with pure water up until the pH value of the precipitate is 6-7, include alumina (1:10) after drying out, blend well, location in an extractor, and also remove with cycloethane. The cycloethane essence was concentrated and permitted to cool, white crystals were precipitated, as well as the crystals and also mommy alcohol were gotten by purification. The crystals were recrystallized with cyclohexane to get Pure Honokiol. After the mother alcohol is concentrated, crystals are precipitated, as well as cyclohexane is recrystallized to get colorless flake crystals, which are magnolol crystals. The return of honokiol was 85%, and also the yield of Pure Honokiol was 74%.
