Experiments were carried out in order to compare the sesamol contents in the methanol extracts and unsaponifiable matters from raw and baked seeds of Korean sesame and perilla by thinchrography. The oil and sesamol contents of sesame seeds were higher than those of perilla seeds. The contents of sesamol in raw and baked sesame seeds were 0.22 and 0.096% respectively in methanol extracts and 0.41 and 0.29% respectively in unsaponifiable matters. The sesame contents in raw and baked perilla seeds were 0.0022 and 0.0043% respectively in methanol extracts and not detected in unsaponifiable matters.
