Analysis of Nutritional Components of Fat and Fatty Acids in Leaves and Stems of Rosemarinus officinalis L.
The nutritional components of fat and fatty acids in leaves and stems of two varieties of Rosemarinus officinalis L.were detected by conventional methods and gas chromatograph.The results showed that the fat of leaves was higher than that of stems.The fat of big leave and small leave of Rosemarinus officinalis L.was 10.3 g/100 g and 9.7 g/100 g,respectively,while the fat of the two varieties of stems of Rosemarinus officinalis L.was 1.8 g/100 g and 2.5 g/100 g,respectively.The fatty acids composition of stems was more than that of leaves.The proportion of unsaturated fatty acids in the total fatty acids of large leave,small leave,the stem of large leave and the stem of small leave was 27.07%,75.68%,78.39%and 75.77%,respectively.This study scientifically expounds the differences of nutrients,fats and fatty acids in different varieties and different parts of Rosemarinus officinalis L.,and provides data support for guiding planting of Rosemarinus officinalis L.and comprehensive utilization and development in the later stage.
