Chemical changes in extractives during storage

Chemical changes in extractives during storage What happens to lipophilic extractives? Even though the total amount of lipophilic extractives does not necessarily change much during storage, their chemical composition, however, does change. The major chemical changes in the resin during wood storage can be divided into three types:1 rapid hydrolysis of triglycerides accompanied by slower
