Plant extracts have traditionally been used as sources of natural antimicrobial compounds, although in many cases, the compounds responsible for their antimicrobial efficacy have not been identified. In this study, crude and dialysed extracts from dandelion root (Taraxacum officinale) were evaluated for their antimicrobial properties against Gram positive and Gram negative bacterial strains. The methanol hydrophobic crude extract (DRE3) demonstrated the strongest inhibition of microbial growth… 

Ethnobotany of the genus Taraxacum—Phytochemicals and antimicrobial activity

TLDR
This genus represents a potential source of bioactive phytochemicals with broad‐spectrum antimicrobial activity and there is limited information on oral bioavailability, pharmacological activities, and safety of Taraxacum products in humans, though their traditional uses would suggest that these plants are safe.

Comparative phytochemical, cytotoxicity, antioxidant and haemostatic studies of Taraxacum officinale root preparations.

Taraxacum Genus: Potential Antibacterial and Antifungal Activity

TLDR
Antimicrobial research indicates that this plant is a promising species for treating common infections in humans, animals, and plants and Phytochemical composition and antimicrobial activity in Taraxacum are neither directly related, nor does the published data provide sufficient information for identifying the group of unique extraction conditions that are optimal against specific microorganisms.

Efficiency of Multiple Extraction Solvents on Antioxidant, Cytotoxic, and Phytotoxic Potential of Taraxacum officinale (L.) Weber ex F.H. Wigg. from Poonch Valley, Azad Kashmir, Pakistan

Background Different parts of Taraxacum officinale (L.) were used in traditional medicine in various parts of the world for the treatment of health problems, and they possess significant biological

A review: antimicrobial properties of several medicinal plants widely used in Traditional Chinese Medicine

TLDR
Further studies are required in the fields of purification and identification of the antibacterial compounds, its mechanisms of action, and synergistic effects in combination with other antibacterial drugs, which may be helpful in the development of new antib bacterial drugs.

Reversal of heavy metal-induced antibiotic resistance by dandelion root extracts and taraxasterol.

TLDR
It is suggested that heavy metals induce bacterial antibiotic resistance and dandelion root extracts and taraxasterol could be used to help reverse bacterial resistance to antibiotics.

The Antibacterial Effect of Humulus lupulus (Hops) against Mycobacterium bovis BCG: A Promising Alternative in the Fight against Bovine Tuberculosis?

TLDR
This is the first study to analyse a wide range of hops for their antimicrobial potential against M. bovis BCG and recommends that further research focuses on other Mycobacteria spp.

Challenges and Considerations in the Preparation of Novel Antibiotic Phytochemicals

TLDR
An overview of experimental designs in ethnobotanical antibiotics investigations is sought, a brief historical survey of ancient investigations into antibiotics is given, and some of the strengths and weaknesses of the various modern methods and techniques routinely employed in ethnOBotanical antibiotic research are identified.

Inositol Derivatives and Phenolic Compounds from the Roots of Taraxacum coreanum

TLDR
In this study, the characterization of chemical constituents and biological activity of the roots of Taraxacum coreanum (Asteraceae) was attempted and vanillic acid, isoferulic acid and syringaresinol showed radical scavenging activity with IC50 values ranging from 30.4 to 75.2 μM.

A comprehensive review of the benefits of Taraxacum officinale on human health

TLDR
It is found that the most frequently reported therapeutic effects of Taraxacum officinale include hepatoprotective, antioxidant and anticancer activities.

Plant Products as Antimicrobial Agents

TLDR
The current status of botanical screening efforts, as well as in vivo studies of their effectiveness and toxicity, are summarized and the structure and antimicrobial properties of phytochemicals are addressed.

CHEMICAL SIGNIFICANCE OF THE VOLATILE COMPONENTS OF SPICES IN THE FOOD PRESERVATIVE VIEWPOINT-IV

TLDR
It was found that carvacrol, thymol, isoborneol, vanilline and salicylaldehyde show antibacterial activity in dilutions 2, 000 or over and addition of vanilla or eugenol as an essence to fish ham or fish sausage would be effective for the preservation of these food products.
