The chemical structure of 1 was elucidated as cyclo -( Leu-Thr) based on spectral methods. From the roots of Panax ginseng five known lactams (16 - 20 ) includingpyroglutamic acid were isolated together with butyric diacid, daucosterol and sucrose. The primary bioac-tivity test showed that pyroglutamic acid and its n-butyl derivative have weak Ca2+ antagonistic activity.
