Antimicrobial activities of Caucalis platycarpos L. and Eryngium caucasicum Trautv. essential oils

Abstract

Caucalis platycarpos L. and Eryngium caucasicum belong to Umbelliferae and are well represented in the flora of Iran by about 120 genera, 3500 species, and 100 endemic plants. This family is really valuable from economic and medicinal points of view and some species of this family are well known either because they have medicinal properties or because of great essential oils that they contain. Additionally, the mentioned genus has been wildly used in traditional medicine in Iran as an antitumor, antioxidant, antibacterial, and anti-inflammatory agent. In this regard, this study was conducted to provide useful information about essential oils of these two species. Volatile constituents of aerial parts of Caucalis platycarpos L. and Eryngium caucasicum Trautv. were investigated using gas chromatography/mass spectrometry (GC-MS) and gas chromatography/flame ionization detection (GC-FID). Antimicrobial activities of the essential oils were tested against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Bacillus subtilis using a disc diffusion method. The essential oils were mainly composed of trans-pinocarvyl acetate and caryophyllene oxide considered as the most significant constituents. According to a minimum inhibitory concentration (MIC) and a minimum bactericidal concentration (MBC), the essential oils showed antimicrobial effects. Moreover, the oils extracted from E. caucasicum and C. platycarpos indicated antibacterial activities against S. aureus and B. subtilis.

Antimicrobial and Antioxidant Activities of Two Medicinal Plants Cuphea aequipetala var. hispida (Cav.) Koehne and Eryngium comosum Delaroche F Against Bacteria Related to Equine Infections

“…Present results from TP quantifications (22.1 mg GAE/mL) are higher than those for E. foetidum, E. maritumum, and E. planum (1.82e8.9 mg GAE/mL). Nonetheless, more sophisticated extraction methodologies reported higher TP results (58.8e105.5 GAE/mL) as it was cited for E. caucasicum [56,57].…”

“…Takahashi et al [55] cited no antimicrobial effect over E. coli O 157:H7 and S. enterica strains from ferulic acid. Mohamadipour et al [56] reported Eryngium caucasicum Trautv. essential oil with inhibition growth effect over E. coli and other gram-negative and gram-positive strains.…”

Antimicrobial Metabolites of Caucasian Medicinal Plants as Alternatives to Antibiotics

“…The modified family of terpenes are terpenoids, synthesized by the addition/removal of functional groups to/from terpenes [127] and comprising 40,000 compounds including terpenoid-derived indole alkaloids [128]. Terpenes and terpenoids were detected in the aerial part and the roots of E. caucasicum [30,31], A. fragrans aerial parts [32], roots [34] and flowers [33], and P. fraxinifolia stems [42], as well as in aerial parts of C. nepeta [43,44], M. pulegium [46,47], and T. caucasicus [48] and the leaves of L. nobilis [50]. In these Caucasian medicinal plants, camphor, terpinene, piperitone, pinene (Scheme 1), and their derivatives were the most frequently detected terpenes (Table 2).…”

Antimicrobial Activity and Analysis of the Essential Oils of Selected Endemic Edible Apiaceae Plants Root from Caspian Hyrcanian Region (North of Iran)

“…This unique ecosystems, contribute significantly valuable territorial/ ethno-medical applications for local people. 22,23 Among the territorial plants, many Apiaceous endemic species have been used as common spices among Hyrcanian people. Among them, the four plants, Elaeosticta glaucescens Boiss (locally called Shividak), Eryngium caucasicum (locally called Avieh or Choochakh), Caucalis platycarpos (Bur parsley, Jafari-e-derakhshan), and Malabaila secacul (Persian hogweed, golpar-e-vahshi) were collected from the wild population as vegetables and sold commonly in local markets.…”
