Relevance:
Plants of the genus
Salvia
are rich in biologically active compounds. Studying the
lipid complex of the above-ground parts of sage is important for assessing its potential as a source of
functionally valuable polyunsaturated fatty acids and related components.
The aim of the study:
To study the quantitative and qualitative composition of lipids in the
above-ground part of sage, to determine the ratio of neutral and polar lipids, their fatty acid profile
and to identify biologically significant components.
Materials and methods:
Object – air-dried above-ground part of sage (
Salvia sp
.).
Neutral lipids (NL) were extracted with gasoline (b.p. 75–80°C), and polar lipids (PL) were
extracted using the Folch method with a chloroform–methanol mixture (2:1). The resulting fractions
were purified to remove impurities and analyzed spectrophotometrically and by thin-layer
chromatography. Fatty acid composition was determined by gas chromatography.
Results:
The moisture content of the raw material was 7.1%. Total lipids were 9.2% of the
above-ground part weight, including 7.8% of NL and 1.4% of PL.
Chlorophyll pigments were detected in the NL: 11.7 mg/l chlorophyll a and 5.1 mg/l chlorophyll
b.
The qualitative composition of NL is represented by hydrocarbons, fatty acid esters with
phytosterols and triterpenols, triacylglycerides, free fatty acids and alcohols, triterpenols, phytosterols
and chlorophyll pigments.
Glycolipids and phospholipids have been identified in the composition of PL.
The fatty acid profile includes 9 components:
– linoleic (44.3%) and oleic (19.9%) acids dominate in NL;
– linoleic (34.9%) and α-linolenic (29.3%) acids predominate in PL.
The total content of unsaturated fatty acids is 79.1% in NL and 77.2% in PL, saturated – 20.9%
and 22.8%, respectively.
Conclusions.
The aerial parts of sage contain significant amounts of lipids, including
biologically valuable polyunsaturated fatty acids. The data obtained confirm its potential as a source
of lipids with potential functional activity.
