Isomerization of Co2 extracted Crude

I have been hearing of people having problems with distilling Co2 extracted crude oil. Most people are experiencing a decrease in potency and a mystery peak show up on their HPLC’s. I have been told this is due to the pH of the crude being off. I’m wondering if anyone has experienced this, knows what is causing it, and if there is a simple fix for it. Thanks in advance.
