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

Lipid and volatile compositions of Borago officinalis L. leaf were 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 mainly consisted of phosphatidylcholine as the major phospholipid, whereas monogalactosyldiacylglycerol was the major glycolipid. Concerning 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.
