Abstract From the aerial parts of Sideritis chamaedryfolia six previously known ent -kaurene diterpenoids have been isolated. In addition, seven newlabdane derivatives have also been obtained from the same source. The structures of these new natural diterpenoids have been established by chemical spectroscopic means and by correlation with known products.
