Results in the journal Cannabinoids. Team investigated 4 extraction solvents – naphtha, petroleum ether, ethanol & olive oil.

Organic Cnidium Monnieri Extract. Osthole is extracted from cnidium monnieri,specification conventional 35%, 50%, etc. Osthole of the low content is yellow-green powder, Osthole of high levels is white needle-like crystal powder. Osthole was dissolved in an alkali solution, methanol, ethanol, chloroform, acetone, ethyl acetate, and boiling petroleum ether, etc., Osthole do not dissolve in water and petroleum ether.
