Antibacterial and Anti-Glucosyltransferase Activity of Verbascum speciosum Against Cariogenic Streptococci.
Objectives: Dental caries is a prevalent chronic human infection worldwide and several plants have shown anticariogenic properties through antibacterial activity against oral pathogens. The present study aimed to assess anticariogenic activity of Verbascum speciosum, in search of novel agents for the prevention and treatment of dental caries.
Methods: Hydro-alcoholic extracts from flowers and total aerial parts of the plant were prepared by maceration. Antibacterial activity of the extracts against Streptococcus mutans (ATCC 35668) and Streptococcus sobrinus (ATCC 27607) was investigated by agar diffusion and microdilution techniques. Inhibitory concentration-fifty values of the flowers' extract against Streptococcus mutans glucosyltransferase enzymes were determined. The total flavonoid content of the extracts was determined using an aluminum chloride reaction.
Results: Verbascum speciosum flowers' extract showed significantly higher flavonoid content and antibacterial activity; with minimum inhibitory concentrations of 100 and 200 µg/mL for Streptococcus mutans and Streptococcus sobrinus, respectively. The extract inhibited the synthesis of glucan by cell-associated and extracellular glucosyltransferase enzymes in a dose-dependent manner with higher activity against the extracellular enzyme.
Conclusion: This study indicated effective anticariogenic activity of Verbascum speciosum flowers extract. This extract can be considered as an alternative to current anticaries therapies or an additive to dental care products.
期刊介绍：
The Journal of Pharmacopuncture covers a wide range of basic and clinical science research relevant to all aspects of the biotechnology of integrated approaches using both pharmacology and acupuncture therapeutics, including research involving pharmacology, acupuncture studies and pharmacopuncture studies. The subjects are mainly divided into three categories: pharmacology (applied phytomedicine, plant sciences, pharmacology, toxicology, medicinal plants, traditional medicines, herbal medicine, Sasang constitutional medicine, herbal formulae, foods, agricultural technologies, naturopathy, etc.), acupuncture (acupressure, electroacupuncture, laser acupuncture, moxibustion, cupping, etc.), and pharmacopuncture (aqua-acupuncture, meridian pharmacopuncture, eight-principles pharmacopuncture, animal-based pharmacopuncture, mountain ginseng pharmacopuncture, bee venom therapy, needle embedding therapy, implant therapy, etc.). Other categories include chuna treatment, veterinary acupuncture and related animal studies, alternative medicines for treating cancer and cancer-related symptoms, etc. Broader topical coverage on the effects of acupuncture, the medical plants used in traditional and alternative medicine, pharmacological action and other related modalities, such as anthroposophy, homeopathy, ayurveda, bioelectromagnetic therapy, chiropractic, neural therapy and meditation, can be considered to be within the journal’s scope if based on acupoints and meridians. Submissions of original articles, review articles, systematic reviews, case reports, brief reports, opinions, commentaries, medical lectures, letters to the editor, photo-essays, technical notes, and book reviews are encouraged. Providing free access to the full text of all current and archived articles on its website (www.journal.ac), also searchable through a Google Scholar search.
