“…The potential beneficial pro-health effects associated with the intake of Nepeta species have been suggested to be partly attributable to their content of essential oils and phenolic compounds [1,[9][10][11][12][13][14][15][16], which have been reported as the major secondary metabolites of this genus [16][17][18]. Among these, rosmarinic acid appears to be the most abundant phenolic compound [1,17,[19][20][21][22].…”

Nepeta curviflora Boiss. (Syrian catnip) is native to the Middle East. This medicinal plant is commonly used against nervous disorders, rheumatic pains, and high blood pressure. Herbal infusions prepared from various Nepeta spp. are extensively consumed as functional food. However, limited information has been known about the phenolic constituents of Syrian catnip. In this study, two acylated flavone 7-O-glucuronides, apigenin 7-O-(2″-O-(2‴-(E-caffeoyl)-β-glucuronopyranosyl)-β-glucuronopyranoside) (1) and luteolin 7-O-(2″-O-(2‴-(E-caffeoyl)-β-glucuronopyranosyl)-β-glucuronopyranoside) (2), along with the known phenolic compounds rosmarinic acid, caffeic acid, apigenin, and apigenin 7-O-β-glucopyranoside were isolated from the aerial parts of N. curviflora. The characterizations of these compounds were based on high-resolution mass spectrometry, UV, and extensive use of multidimensional NMR spectroscopy. The new compounds (1 and 2) were identified in the unmodified state and as dimethylesters.

“…Interestingly, the antimicrobial activity of this compound has been reported and subsequently proposed to be the main bioactive antimicrobial agent identified in the ethyl acetate extract of marine Burkholderia cepacia [ 20 ]. Furthermore, the other major compound detected in the extract, oxirane tetradecyl has been identified as one of the bioactive antimicrobial compounds of the red algae Laurencia brandenii and Senecio pedunculatus [ 21 , 22 ]. In another study, the leaf extract of Andrographis peniculata demonstrated strong antimicrobial, antioxidant and anticancer activities, which were attributed, in part, to 9, 12, 15-octadecatrienoic acid, ethyl ester, (Z, Z, Z) [ 23 ].…”

Objective:The aim was to determine the chemical constituents and antimicrobial activity of the hexane leaf extract of Anisopus mannii against a wide range of human pathogenic microorganisms.Methods:The chemical constituents of the hexane leaf extract was determined using gas chromatography-mass spectrometry (GC-MS) analysis; and the antimicrobial activity was evaluated on “standard strains”, clinical susceptible and resistant bacterial and fungal isolates using the disc diffusion and broth microdilution methods.Results:GC-MS analysis of the hexane leaf extract revealed 32 compounds, representing 73.8% of the identified components. The major compounds were hexadecanoic acid, ethyl ester (34%), oxirane, hexadecyl- (11%) and 9, 12, 15-octadecatrienoic acid, ethyl ester, (Z, Z, Z) (9.6%). Results from the antimicrobial activity demonstrated higher inhibition zones against Bacillus cereus (29 mm), followed by Streptococcus pyogenes (28 mm). Other notable inhibitions were observed with Enterococcus faecalis (27 mm), Proteus vulgaris (26 mm) and MRSA (25 mm). The MIC values ranged from 0.625 mg/mL to 1.25 mg/mL while the MBC/MFC values ranged from 2.5 mg/mL to 5.0 mg/mL.Conclusion:These results support the traditional use of the plant and demonstrate the huge potential of A. mannii as a source of antimicrobial compounds.

“…The application of essential oils (EOs) against microorganisms increased, and it is known that Nepeta oils also have such effects. The EOs of this genus were found to be rich in iridoid monoterpenoids, which exhibited many in vitro/in vivo biological activities including antioxidant, antimicrobial, anti-inflammatory, cytostatic, phytotoxic, and repellent properties [4][5][6][7][8][9][10]. In general, bioactivities of Nepeta EOs are attributed to the presence of nepetalactones (NLs) that have been used as the phytochemical markers.…”

Essential oils (EOs) of three Iranian cultivated Nepeta species were investigated. The oils were obtained by hydrodistillation of air-dried plant materials at full flowering stage and analyzed by gas chromatography (GC) and gas chromatography coupled to mass spectroscopy (GC/MS). In total, 89 compounds were detected. In over 2 years, a number of constituents were identified in the EO of Nepeta binaloudensis first and second years (26 and 37, respectively), Nepeta cataria (25 and 32, respectively), and Nepeta assurgens (45 and 50, respectively). In the oils of N. binaloudensis, 4a-α,7-α,7a-α-nepetalactone (NL) 59.7% and 1,8-cineole (19.6%) during the first and second years, respectively, were the main constituents. The main components of N. cataria were 4a-α,7-α,7a-β-NL (72.8%) and 4a-α,7-β,7a-α-NL (73.9%) during the first and second years, respectively, and 4a–α,7-α,7a-α-NL (55.5%) and 1,8-cineole (24.1%) during the first and second years, respectively, were the main constituents of N. assurgens. The results showed that NLs isomers and 1,8-cineole were the main components of the oils of three cultivated Nepeta species.
