“…Vice versa, major group in E. macrophylla is constituted by sesquiterpenoids (54.5%) while they are only 11.8% of the total oil of E. adenantha. In a previous study on the oil of E. laciniata, relative constituents of the oil were found to be 75.6% of linear hydrocarbons and their derivatives and 9.1% of sesquiterpenoids which is similar to the findings on the oil of E. adenantha (20). Eremostachys adenantha and E. laciniata have been placed together in the "tubulus annulatus" group of the Mollucelloides subgenus of Eremostachys genus (15).…”

The essential oils of Eremostachys adenantha and Eremostachys macrophylla have been investigated by GC and GC/MS. Seventy-six compounds of E. adenantha and thirty-five of E. macrophylla representing 91.2% and 92.9% of the oils were identified, respectively. The main constituents of the oil of E. adenantha were dodecanal (12.7%), hexadecanoic acid (9.9%) and 6,10,14-trimethyl-2-pentadecanone (9.0%); while for E. macrophylla, they were spathulenol (23.4%), hexadecanoic acid (13.5%) and caryophyllene oxide (9.3%).

“…A decoction of the roots and flowers of E. laciniata has traditionally been taken orally for the treatment of allergies, headache and liver diseases (Said et al, 2002). A previous phytochemical study on E. laciniata revealed the presence of various mono-and sesquiterpenes in its essential oils (Navaei and Mirza, 2006). The crude extract of this plant was reported to possess a freeradical-scavenging property (Erdemoglu et al, 2006).…”

Eremostachys laciniata (L) Bunge (family: Lamiaceae alt. Labiatae; subfamily: Lamioideae) is one of the 15 endemic Iranian herbs of the genus Eremostachys. A decoction of the roots and flowers of E. laciniata has traditionally been taken orally for the treatment of allergies, headache and liver diseases. Three antibacterial iridoid glucosides, phloyoside I (1), phlomiol (2) and pulchelloside I (3) have been isolated from the rhizomes of this plant. The structures of these compounds were elucidated unequivocally by a series of 1D and 2D NMR analyses. The antibacterial activity and brine shrimp toxicity of these compounds were assessed using the resazurin microtitre assay and the brine shrimp lethality assay, respectively. All three iridoid glycosides 1-3 exhibited from low to moderate levels (MIC = = = = = 0.05-0.50 mg/mL) of antibacterial activity. Of these compounds, compound 3 was the most active, and displayed antibacterial activity against 9 of 12 different strains tested. The most noteworthy activity of 3 was against Bacillus cereus, penicillin-resistant Escherichia coli, Proteus mirabilis and Staphylococcus aureus with an MIC value of 0.05 mg/mL.

Background: Eremostachys macrophylla Montbr. & Auch. is one of the wild growing species of herbs found in East Azerbaijan province of Iran. These species are used in folk medicine for the healing of wound, treatment of snake bites, rheumatism and joint pains. The primary aim of this study was to obtain natural pure compounds and this was done by subjecting the aerial parts of Eremostachys macrophylla Montbr. & Auch. to phytochemical analysis. Methods: The air-dried and crushed aerial parts were respectively extracted with n-hexane, dichloromethane (DCM) and methanol (MeOH) solvents using a soxhlet apparatus. The 10%, 20% and 40% of MeOH in water Sep-Pak fractions of the MeOH extract were subjected to a preparative reversed- phase high performance liquid chromatography (RP-HPLC). Also, the isolated pure compounds were identified by one-dimensional nuclear magnetic resonance (1D-NMR) spectroscopic technique. Results: The results obtained in this study showed the presence of seven pure components; (1) Lamalbide, (2) Sesamoside, (3) Phlomiol, (4) Verbascoside, (5) Luteolin-7-O- glucoside, (6) Apigenin-7-O- rutinoside and (7) Kaempferol-3-O- glucoside with iridoid, phenylethanoid and flavonoid structures. Conclusion: The results from the study demonstrated that the aerial parts of E. macrophylla could be a good source of iridoids, phenylethanoids and flavonoids.
