Study on the Magnolia Officinalis Extract — Changsha Staherb


1. Magnolia Officinalis extract has natural, efficient, and broad-spectrum antibacterial properties

(1) Effectively fight common bacteria in cosmetics:

Magnolia Officinalis total phenols have broad-spectrum antibacterial ability. The study found that at the concentration of 5-20ug/mL, Magnolia Officinalis total phenols have a significant inhibitory effect on common bacteria and fungi, including Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Salmonella, Saccharomyces cerevisiae, Aspergillus niger [1-3].

(2) Effectively resist oral cariogenic bacteria, periodontal pathogenic bacteria, and halitosis bacteria:

Many studies have shown that honokiol and honokiol have a strong inhibitory effect on five major cariogenic bacteria: Streptococcus mutans, Streptococcus haemolyticus, Actinomyces Neisseria, Actinomyces viscosus, and Lactobacillus, and the MIC can be as low as 3.9 μ g/mL[4]。 The MIC of honokiol and honokiol to periodontal pathogenic bacteria including Actinobacillus actinomycetes, Porphyromonas gingivalis, P. intermedia, Micrococcus luteus, and Bacillus subtilis was 2.5 mg/mL [5]. Because there are more than 300 kinds of bacteria in the mouth, the metabolic products of bacteria are the main cause of bad breath. Research shows that after 30 minutes of consumption of mint sugar added with Magnolia Officinalis extract, 61% of bacteria can be killed [6].

(3) Effectively fight acne bacteria:

Magnolol and honokiol have strong antibacterial activity against Propionibacterium pustulosus and Propionibacterium granulosa, with MIC of 9 respectively μ G/mL and 3-4 μ g/mL[7]。 Propionibacterium pustulosus, also known as Propionibacterium acne, is the main bacteria causing acne and is closely related to the occurrence of acne.

2. Magnolia Officinalis extract has antibacterial and multiple skin care effects

In addition to antibacterial and antiseptic effects, Magnolia Officinalis extract is also a functional skincare ingredient. Magnolia Officinalis and honokiol can synergistically inhibit inflammation [8] and antioxidation [9], improve skin erythema and inflammation, help skin resists aging and maintain a young state.
