From the aerial parts of the endemic species Thymus numidicus Poiret locally which is known as “zaatar”, belongs to the Lamiaceae family five flavonoids were isolated using chromatographic techniques and identified by spectral analysis (UV-Visible, MS, H and CNMR) and chromatographic behaviours.

From the aerial parts of Salvia occidentalis (Labiatae) a new diterpenoid with a rearranged neo-clerodane skeleton was isolated. This new compound was named salvioccidentalin and its structure was established by spectroscopic means. A probable biogenetic relationship with salvigenolide from S. fulgens and salvileucalin A and spiroleucantholide from Salvia leucantha is proposed.

Plant essential oils (EOs) have been reported to have health benefit properties and their preventive and therapeutic use in animals is expected to increase in the future. We evaluated the influence of five essential oils obtained from plant species which are known to have positive antimicrobial, antioxidative and anti-inflammatory effects--sage EO from Salvia officinalis L. (Lamiaceae), oregano...

The genus Dracocephalum L. (Lamiaceae) with about 60 to 70 species is a in the sub-tribe Nepetinae, tribe Mentheae of Lamiaceae family, native temperate regions Northern Hemisphere. They are mostly perennial herbs, and rarely annual. Flora Iranica reports 8 Iran 10 out which, 4 endemic. We collected 7 studied delimitation relationship by morphometric anatomic results. were efficiently delimited...

The volatile oil content and composition of the aerial parts of Ajuga orientalis L. (Lamiaceae) grown in northern parts of Iran have been analyzed by GC/MS. Thirty compounds were identified, representing 97.9% of the total oil. The main compounds were germacrene-D (24.2%), beta-cubebene (18.3%), beta-caryophyllene (16.9%) and alpha-cubebene (5.3%).
