Plants of the genus Scutellaria, commonly known as skullcap, belong to the Lamiaceae family. There are 22 species of Scutellaria in Iran, 10 species of which are native to Iran. Plants of this genus have several effects including neuroprotective, hepatoprotective, anti-cancer, antimicrobial, antiviral, and antioxidant. They are also effective in insomnia and dementia conditions.

The aim of this study was to investigate the composition of essential oils and aromatic waters of some native Scutellaria species from Iran.

Aerial parts of Scutellaria pinnatifida with different subspecies such as mucida, viridis, and alpina, Scutellaria tournefortii, and Scutellaria tomentosa were collected from different regions of Iran. The essential oils and hexane extracts of aromatic waters of selected plants in this genus were obtained by hydrodistillation with clevenger type apparatus and analyzed by GC-MS.

The results of this study showed that germacrene D, caryophyllene derivatives and linalool are found in abundance in the essential oils of these plants. The main terpenoids in the aromatic waters of these plants were linalool and 1-octen-3-ol.

The analysis of the essential oils and aromatic waters of Scutellaria species demonstrated that different geographical factors such as altitude and the season of plant collection can be effective on the production of plant secondary metabolites.

In Iranian culture, aromatic waters harboring a slight amount of essential oil have been popularly used for many years as a pleasant non-alcoholic drink with various medicinal properties.In this study, chemical composition of Zataria multiflora Boiss. (ZM) aromatic water was determined and its in vitro and in vivo antifungal properties were investigated.

Chemical composition of the essential oil extracted from aromatic water (AW) of ZM was analyzed by Gas chromatography and gas chromatography-mass spectrometry (GC-MS). The antimicrobial activity of the AW against Candida species was determined by broth micro-dilution methods. Additionally, biofilm formation inhibition and antioxidant activity of the AW were measured using XTT reduction and DPPH methods, respectively. Antifungal activities of the AW in the prevention and/or treatment of gastrointestinal (GI) candidiasis in animal models were also evaluated.

The GC-MS analysis revealed that the major constituents of ZM AW were Carvacrol (46.56%) and Thymol (40.67%). The ZM AW inhibited the growth and biofilm formation of Candida species in the range of 0.25-0.5 V/V. Moreover, ZM AW significantly decreased Candida colonization in therapeutic groups (P<0.05).

Given the wide therapeutic potential of ZM AW, including antifungal and antioxidant activities, it might be possible to use it in the management of mucocutaneous or alimentary candidiasis.

Aromatic waters (AWs) are therapeutic distillates, which harbor both essential oil and water-soluble components of a plant. Due to the dispersion of the light amount of essence through the AWs, they have their specific pleasant smell, taste, and medicinal properties. In Iranian traditional medicine, Trachyspermum ammi AW is used to treat gastrointestinal disorders. The present study was conducted to determine the chemical composition of the essential oil extracted from T. ammi AW and its antifungal activities against Candida species.

The composition of the essential oil extracted from T. ammi AW was analyzed by gas chromatography-mass spectrometry. In addition, the evaluation of the antifungal activity of AW against Candida species was performed using broth microdilution methods as recommended by the Clinical Laboratory Standard Institute. Moreover, the biofilm formation inhibition, antioxidant properties, and experimental activity of AW were determined in an animal model.

According to the results, thymol (78.08%) was the major compound of EO, followed by carvacrol (8.20%) and carvotanacetone (6.50%). Furthermore, T. ammi AW exhibited antifungal activities against the examined fungi and inhibited the biofilm formation of C. albicans at a concentration of up to 0.25 V/V. Histopathological analyses revealed that Candida colonization declined in the mice following the administration of T. ammi AW in a therapeutic trial.

It seems that the presence of phenolic monoterpenes in AW has resulted in antifungal effects. Pleasant odor and antioxidant properties are extra bonuses to the antimicrobial effects of this plant. Based on the findings, AW might have the potential to be used in the management of alimentary candidiasis or oral hygienic products.

Current study aimed to chemically assess volatile constituents of eleven commercial cinnamon hydrosols purchased from Fars province (Iran) local markets in comparison to a standard sample. Via a liquid extractor, the volatile oil fractions of samples and also the standard hydrosol yielded from essential oil extraction of an authenticated cinnamon bark sample were recovered. Gas chromatography/ flame ionization detector (GC/FID) and subsequently GC/MS (GC/mass spectroscopy) were employed to assess and identify the chemical compositions of prepared samples. The procedure of analysis revealed in the appearance of totally 25 components. Cinnamaldehyde was found as the main constituent in ten populations (S2-S11) as well as in the standard sample (63.04-91.61%). Considerable amounts of Dibutyl phthalate, as a commonly used plasticizer was also detected in all samples. This is the first report of analysis and identification of volatile constituent in cinnamon hydrosol, a common medicinal beverage. Although, high amount of Cinnamaldehyde in cinnamon hydrosol can introduce this tasty medicinal beverage for further studies similar to the respective botanical part or various usual extracts, more comprehensive monitoring is to be performed on safety, purity and quality of such preparation.
