In the current research, aerial parts of Salvia verticillata L. were collected during the flowering stage from Esfehan-Khor and its chloroform extract was investigated. Purification of crude extract was carried out by column chromatography on silica gel with a gradient of n-hexan-ethyl acetate. At the end of chromatography, the column was eluted by methanol. Finally thirty-seven fractions were collected; further purification was carried out by column chromatography (smaller columns) and thin layer chromatography (glass plates) in n-hexane–ethyl acetate as solvent for several times and yielded pure compounds. The structure of purified natural products was elucidated by using Nuclear Magnetic Resonance (NMR) spectroscopy and Mass spectrometry. β-sitosterol and two diterpenoides namely Marrubinone B and Peregrinol were isolated.

Nepeta L. genus belongs to Labiatae family that has important medicinal and aromatic species. More than 250 species in world and 67 annual and pernnial species in Iran have been reported. In this investigation, essential oil composition of Nepeta gloeocephala Rech. f., Nepeta sessilifolia Bunge and Nepeta laxiflora Benth have been staudied. The species are endemic to Iran and have natural habitats in Dorien, Ghohroud and Mashhad-e-ardahal of Kashan. The flowering branches of these species were collected in spring and summer and dried in shade (at room temperature). The flowering branches of the species subjected to volatile fraction were isolated by hydrodistillation using a Clevenger-type apparatus for 3 or 4 hours. After decanting and drying of the oils over anhydrous sodium sulfate, they were stored in vial at low temperature (4ºC) before analysis. The analysis of the oils was performed using GC and GC-MS. The results showed that, the essential oil of Nepeta gloeocephala Rech. f. was yellow in 1/3% (v/w) yield and 29 components were identified, among them, 1,8-Cineole (35.2%), Beta-pinene (21.8%), sabinene (7.8%), (E)-beta ocimen (7.1%), alpha-pinene (7.1%) and (Z)-ocimene (6.9%) were the major compounds.

The genus of Nepeta presents 67 species in Iran, most of them are endemic. One of theses endemic species is N. heliotropifolia. In this research the essential oil of N. heliotropifolia was investigated in three different stage of plant growth. The aerial parts of N. heliotropifolia at before flowering, beginning of flowering and complete flowering were collected from Hamedan province. Essential oils isolated by hydro-distillation from the aerial parts of three samples, were analyzed by a combination of capillary GC and GC/MS. The yields of essential oils were obtained 0.75%, 0.63% and 0.4% (w/w) respectively. So the oil yield of N. heliotropifolia was decreased from before flowering stage to complete flowering stage. Thirty-six components were identified in the oils. The main constituent of the essential oil at before flowering stage was limonene (40.1%), that decreased by plant growth. The second main component of the oil in this stage was b-pinene (11.1%), that increased to 23.3% in the beginning of flowering, then decreased in fool flowering. The other main compounds of the oils were 1,8-cineole, b-caryophyllene, (Z)- b-farnesene, g-mmurolene abd bicyclogermacrene.

The genus of Thymus Presents 14 species, which are found wild in different regions of Iran (1). One of the more distributed of these species is Thymus pubescens (2).
The aerial parts of Thymus pubescens were collected from three various localities of Lar valley (in East of Tehran province). Essential oils isolated by steam distillation from the plant material at two stages, before flowering (BF) and full flowering (FF). Yields of essential oils were 0.53% to 0.93% (at BF stage) and 1.23% to 2.03% (at FF stage). Therefore the oil content at BF stage was less than FF stage.
At BF stage 26 compounds (representing 98% to 99.3% of the oils) and at FF stae 32 compounds (representing 97.7% to 98.5% of the oils) were characterized. Major constituents at BF stage were: carvacrol (52.6% - 77.9%), thymol (2.7%-21.8%), g-terpinene (3.3%-7.4%), p-cymene (2.2%-4.4%), and b-caryophyllene (1.7%-2.5%). Major constituents at FF stage were: carvacrol (54.7% - 69.2%), p-cymene (6.7%-9.7%), borneol (1.7%-5.1%), methyl carvacrol (0.6%-6.6%) and 1,8-cineol +limonene (1.7%-3.2%).
Twenty-three constituents were common at two stages. d-cadinene, thymyl acetate and g-muurolene (E)-b-ocimene were found just at BF stage and a-phellandrene, a-terpineole, terpinen-4-ol, spathunelol, camphor, linalool, methyl linalo, methyl thymol, thymoquinone and thymodihydroquinone were found just at FF stage.
