Essential oils are widely recognized as natural alternatives to pharmaceutical antibacterial and antifungal agents. With respect to standard pharmaceutics, the advantages of essential oils are their (i) low production costs, (ii) lack of chemical and biochemical drawbacks that are intrinsic to the synthetic production process and (iii) good toleran...

Origanum syriacum (O. syriacum) (L.) belongs to Group B of the genus Origanum from (Lamiaceae), which is rich in essential oils that exhibit antimicrobial efficacy, anti-inflammatory efficacy, antioxidant activity, and antitumor efficacy. These processing activities are because of its richness in carvacrol and Thymol. In this article, we will focus on O. syriacum, discussing the antimicrobial efficacy for its essential oil and extracts, in addition, cast light on mechanism of essential oil antimicrobial action. This study was conducted from March 2019 to February 2021. We have analyzed the results of studies on antimicrobial efficacy of a plant O. syriacum in the PubMed, Google Scholar, Elsevier over the past 15 years using keywords. O. syriacum essential oil and its extracts have an extensive antimicrobial efficacy give it a great importance in pharmaceutical and medical purposes.
... Glands have one celled head and stalk. ( Sadıkoğlu and Özhatay, 2015) Another feature that strongly dierentiated common oregano and Greek oregano leaves was the density of glandular trichomes situated on the upper and down leaf surface. In Origanum subspecies (as well as in other Lamiaceae), glandular trichomes are multicellular epidermal glands responsible for storage of essential oil. ...
Chemical components act in plant defense and protection, but many of them are extracted and used medicinally. The objective of this study was to evaluate and compare throw a histochemical test the structure and chemical secretions of the glandular trichomes of two different species from Lamiaceae family. These two plants are the well-known medicinal plants of Ocimum basilicum L. and Origanum vulgare L. cultivated in vivo and in vitro in different locations and conditions in Albania. As samples we have used fresh leaves which have been prepared for investigation throw these techniques: a) fresh hand-cut sections, b) epidermis peel off technique and c) fixing sections. The prepared samples have been stained with chemical dye for the detection of specific chemicals produced by the leaves of these plants. Tests were conducted for lipids, terpenoids, phenolic compounds, alkaloids, and tannins. For both species O. basilicum L. and O. vulgare L. we noted the presence of three types of trichomes: nonglandular trichomes and glandular trichomes (capitate and peltate) which are present both on the adaxial and abaxial leaf surfaces. In the the glandular hairs of both species we noted the presence of various chemicals in different quantity (the evaluation is done based on the intensity of the staining). Between these two species we could note that there are significant differences in the type of glandular trichomes and also the most common secondary metabolites present on these glands are phenols and alkaloids.
Keywords: capitate, chemical components, glandular trichomes, peltate.
