Area Of Science
- Phytochemistry
- Pharmacology
Background
- Phlomis olivieri Benth. is an aromatic, endemic species from Iran, belonging to the Lamiaceae family.
- This plant is recognized for its potential medicinal properties.
Purpose Of The Study
- To isolate and analyze the essential oil of Phlomis olivieri from four different Iranian populations.
- To investigate the antioxidant activity of the isolated essential oil using the DPPH radical scavenging assay.
Main Methods
- Aerial parts of Phlomis olivieri were collected, dried, and milled.
- Essential oil was extracted using a Clevenger apparatus and analyzed by Gas Chromatography-Mass Spectrometry (GC-MS).
- Antioxidant activity was determined by measuring the scavenging of stable 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals.
Main Results
- Seventeen constituents were identified in the essential oil, with caryophyllene being the most abundant (24.093%).
- Significant differences in antioxidant activity were observed among the populations (ANOVA, F(3, 8)=50.42).
- The Hamedan population exhibited the highest antioxidant activity (159.17 ± 10.50 µg/ml), while the Kurdistan population showed the lowest (69.45 ± 3.24 µg/ml).
Conclusions
- Phlomis olivieri possesses essential oil with notable antioxidant properties.
- The chemical composition and antioxidant activity vary across different geographical populations.
- This species holds potential for applications in various fields due to its constituents and antioxidant capacity.

The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...
In general, the term ‘aromatic’ indicates a pleasant smell or fragrance from fresh flowers, freshly prepared coffee, etc. In the early history of organic chemistry, many benzene derivatives were isolated from the pleasant odor oils of the plants. For example, vanillin was isolated from the oil of vanilla, methyl salicylate from the oil of wintergreen, and cinnamaldehyde from the oil of cinnamon. They all had a pleasant odor; hence the name aromatic was given.
In 1825, Faraday...
An acid can be deprotonated to form a conjugate base or an anion. If the produced anion is more stable, then the acid is stronger. On the contrary, if the anion is unstable, then the acid is weaker. Hence, to determine the acidity of the compound, the stability of its conjugate base is studied using various factors.
The size effect explains the change in atomic size on acidity. When comparing the acids formed from elements that belong to the same column in the periodic table, their atomic sizes...
Adrenergic agonists' structure-activity relationship (SAR) determines their selectivity and efficacy. These agonists comprise a phenylethylamine moiety with an aromatic ring and an ethylamine side chain.
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
Separation of...
Vanillin—a flavoring agent in vanilla, cinnamaldehyde—a molecule responsible for the distinct smell of cinnamon, and acetone—a strong-smelling ingredient in nail polish removers, all belong to a class of carbonyl compounds called aldehydes and ketones (Figure 1). Although both aldehydes and ketones contain the characteristic carbonyl (C=O) bond, their chemical structures vary with respect to the groups directly attached to the carbonyl carbon.
In aldehydes (Figures 1a and 1b),...
Like water, alcohols are weak acids and bases. This is attributed to the polarization of the O–H bond making the hydrogen partially positive. Moreover, the electron pairs on the oxygen atom of alcohol make it both basic and nucleophilic. Protonation of an alcohol converts hydroxide, a poor leaving group, into water—a good one. The two acid–base equilibria corresponding to ethanol are depicted below.
