Aromatic plants
Abstract:
Volatile oils (aromatic essences) have been well known since ancient times, both as
food flavors and as a treatment solution for sanitary and cosmetic purposes.
In order to highlight the content in the volatile oils and their composition, a number
of fresh aromatic plants have been studied, as: lavender (Lavandula angustifolia),
rosemary (Rosmarinus officinalis), sage (Salvia officinalis), thyme (Thymus vulgaris)
and oregano (Origanum vulgare), all originated from the organic crops of the Hofigal
Company.
Essential oils were obtained by using the water vapor extraction technique, while for
the identification of volatile oil components was used gas chromatography coupled
with mass spectrometry (GC-MS).
The experimental results present the volatile oil content of the studied aromatic plants
and also the important and specific chemical components of each volatile oil.
Likewise, the soils used for plants growth have been analyzed for organochlorine
content by using gas chromatography with electron capture detector (ECD). The
concentration of these organic compounds is below the maximum allowable limit
established by specific law (Order no. 756/1997) for soils of Romania.
These volatile oils from organic sources will be used as raw materials for obtaining
food supplements and cosmetics products.
