Monoterpenoid Polyols in Fruit of Cnidium monnieri.

Five new monoterpenoid polyols were obtained from the fruits of Cnidium monnieri CUSSON (Umbelliferae). They were characterized as distereomers of 3, 7-dimethyloctane-1, 2, 6, 7-tetrols (3 and 4), (6, 7-threo)- and (6, 7-erythro)-3, 7-dimethyloct-3(10)-ene-1, 2, 6, 7, 8-pentols (5 and 6) and trans-p-menthane-1β, 2α, 8, 9-tetrol (7), respectively.
