Salvia officinalis L. is well known as an aromatic and medicinal plant in Albania. Several studies suggest that Salvia officinalis L., in addition to treating minor common illnesses, might potentially provide novel natural treatments for the relief or cure of many serious and life-threatening diseases such as depression, dementia, obesity, diabetes, lupus, heart disease, cancer or antibacterial treatments. The most common methods used for obtaining extracts of essential oils are water distillation, distillation with organic solvents such as hexane, ethanol, methanol and extraction with liquid CO2 under pressure as well. The extracts fractions obtained by these methods are of interest especially in the fields of pharmacology, cosmetic, medicine, food chemistry etc. In this study the extraction of essential oil from Salvia officinalis L is carried out by using an organic solvent (hexane) and liquid CO2 solvent under pressure at 40 0 C. The essential oil extracts are analyzed by thin layer chromatography. The amount of essential oil and the overall yield obtained by hexane distillation method is lower than that obtained by CO2 extraction method. These findings demonstrated that the amount of S. Officinalis oils obtained by CO2 extraction method is optimal, making that suitable for a possible use in pharmaceutical purposes.

Gas Chromatographic Method

Numerous articles on Salvia officinalis L. have been published regarding the composition of their essential oil. The considerable variation found may be due to the quality of the plant material as well as to the methods used for analysis. A simple GC-MS method was developed and optimized in the QbD approach, for the determination of sage essential oils. The optimization of GC-MS analysis was performed using different mobile phase flows, injection volumes, split ratios and temperature programs. The optimized method proved to be simple and can be successfully applied for the determination of sage essential oils.

Abstract In this study the effects of Salvia officinalis L. essential oil on the thickness of the gut mucus layer and quantity of neutral and acidic mucins in chickens were observed. Oneday-old chickens of Isa Brown breed were divided into five groups (n = 9) and fed 11 weeks as follows: control group (C): basal diet; experimental groups (E1 - E4) - same as C + sage essential oil (EO) in concentrations of 0.01%; 0.025%; 0.05% and 0.1%, respectively. The thickness of the mucus layer in the duodenum significantly increased in E3(0.05% sage EO) compared to E1 (0.01 % sage EO). In E3 (0.05% sage EO) the number of goblet cells containing acidic and neutral mucins was significantly decreased in the duodenum and jejunum and increased in the ileum compared to C. Feeding the diet supplemented with Se and 0.01% sage EO (E1) decreased plasma cholesterol level in comparison with E3(0.05 % sage EO). The addition of 0.05% (E3) and 0.1% sage EO (E4) to the diet caused a decrease in calcium plasma level compared to E2 (0.025 % sage EO). Plasma glucose level was significantly decreased in groups fed 0.05% (E3) and 0.025% sage EO (E2) compared with 0.01% sage (E1). The weight of internal organs was not affected by the diets. Our results suggest that effects of sage EO on the adherent mucus layer dynamics and mucin type distribution in the chicken intestine are dependent on sage EO dose and intestinal segment and there is still a need for further studies in order to obtain a plausible explanation.
