Polar Lipid Extraction and Analysis During Conifer Needle Abscission.

Extracting and analyzing polar lipids during conifer needle abscission is crucial for comprehending the associated lipid dynamics. A combination of polar and nonpolar solvents for lipid extraction is actively used in lipid analysis during conifer needle abscission. Conifer needle tissue is particularly difficult to work on for several reasons, which must be considered during sample preparation and lipid extraction. Further, conditions like in situ tissue harvest, postharvest tissue harvest, and extraction protocol influence the analysis of target lipids in the plant. The use of electrospray ionization tandem mass spectrometry (ESI-MS/MS) facilitates the simultaneous and thorough analysis of many polar lipids in conifer tissue samples.
