The fatty acid (FA) composition of callus lipids in two larix species (Larix gmelinii and Larix sibrica) was studied by gas-liquid chromatography. Callus lipids were characterized by a high content of unsaturated FAs: 57,7% in L. gmelinii and 59,9% L. sibirica. Among them, oleic and linoleic acids predominated (11,2 and 24,5% of total FAs in L. gmelinii and 14,8 and 26,6% in L. sibirica, respectively). Callus lipids also contained Δ5-UPIFA (unsaturated polymethylene-interrupted FAs (12,3% in L. gmelinii and 11,2% in L. sibirica, respectively), where pinoleic and sciadonic acids predominated. Callus lipids also contained high content of VLCPUFA (С20, C22, C23, C24) 11,4% in callus L. gmelinii and 9,1% L. sibirica.
