BIOCHEMICAL AND PHYSYOLOGICAL RESEARCHES IN SALVIA NEMOROSA L.
Journal Title: Analele Stiintifice ale Universitatii Alexandru Ioan Cuza din Iasi, Serie noua, Sectiunea II a. Biologie vegetala - Year 2010, Vol 56, Issue 2
Abstract
The paper presents a few biochemical and functional characteristics in Salvia nemorosa L. (Lamiaceae), an aromatic and medicinal plant widely spread in Romania. The biochemical investigations aimed at dosing the leaf assimilating pigments dosing, water and dry substance content and volatile oil composition (as products having aromatic and phototherapeutic properties ) of oils secreted in different ontogenetic stages. Water and dry substance content has been determined using the gravimetric method and the assimilating pigments (chlorophyll and carotenoid pigments) have been dosed using the spectrophotometric method. Volatile oils have been extracted through hydrodistilation using a Clevenger apparatus. The compounds separation had been carried out through gas-chromatography using an Agilant GC-MS 6890 device. The identification of volatile compounds has been carried out using a spectrum bank. In the studied material, hydration level, dry substance content, assimilating pigments content produced by the leaves varies with to the harvesting moment (plant age) and with the investigated organ (component fractions of the volatile oil).
