LIPID COMPOSITION OF PAULOWNIA SEEDS GROWN IN BULGARIA

The chemical composition of seeds from paulownia (Paulownia tomentosa) was investigated. The main components in the triacylglycerol fraction of the oil were linoleic (64.1%), oleic (21.2%) and palmitic acids (7.3%). ?-Tocopherol (approx. 100.0%) predominated in the tocopherol fraction, and in the sterol fraction – ß-sitosterol (79.2%), campesterol (10.3%) and stigmasterol (7.7%). In the seeds were established 10.6% protein, 9.5% cellulose and 38.2% hydrolysable carbohydrates.
