Gas chromatography and AromatogramAn in-depth analysis is required to identify the complete composition of an essential oil and to establish in an accurate way its nature and quality. This analysis is called Gas chromatography and it is usually paired with mass spectrometry. This mixed method, highly sensitive and specific, structurally identifies the molecules contained in the essential oil from a quali-quantitative point of view, essential for a chemical typification in relation to the botanic identity. Moreover it can reveal the presence of contaminative or foreign substances that can invalidate the quality of the product and/or change it. FLORA does this analysis on every essential oil and parcel, before putting it onto the market in order to identify the chemotype of the essential oil and all the other chemical components, needed by the therapist to treat diseases. This is why we print on the label the main four or five chemical components of the essential oil.
Aromatogramm: a technique to rediscover and implement before the treatment!
It is a method of in vitro measurement of the antibacterial power of essential oils towards a determined strain of pathogenic bacteria, isolated from an ill subject. During the 50s many researches (among them: Valnet, Belaiche and Lapraz) studied the bactericide power of 175 aromatic essences. Using these researches, they worked out an aromatic index, using a laboratory method called Aromatogram.
Essential oils can block some of the metabolic functions of the germ, such as growth and reproduction as well as determine its lysis. This type of analysis is carried out before starting the treatment of infectious pathologies, often resistant to antibiotics.
To perform an Aromatogram one needs to rely on qualified laboratories supplied with essential oils by FLORA. Today it is more sophisticated because of the determination of other quantitative parameters , thanks to the possibility of carrying it out in liquid phase or better on microplates, paying attention to both the accurate preparation of the microbial inoculum and the emulsion of essential oils in broth culture.
