Lipid and volatile composition of Borage (Borago officinalis L.) leaf

Lipid and volatile composition of Borago officinalis L. leaf was investigated. The results showed that α-linolenic acid was the major fatty acid followed by stearidonic acid. Total lipids were composed of neutral and polar lipids. Polar lipids were mainly composed of phosphatidylcholine as the major phospholipid, whereas monogalactosyldiacylglycerol was the major galactolipid. Quant to neutral lipids, they were mainly composed of triacylglycerols. The volatile composition exhibited the presence of many green note compounds such as hexanal, (E)-2-hexenal, hexanol, (Z)-3-hexenol, (E)-2-hexenol and nonanol. Borage leaf appears to be an important source of essential fatty acids, phospholipids, glycolipids and green note volatile compounds for food, cosmetic, pharmaceutical and biomedical applications.
