Abstract
Two new isopimarane-type diterpenes named orthosiphonones A and B and a new benzochromene named orthochromene A, have been isolated from the water dec oction of the leaves of Orthosiphon aristatus (Lamiaceae) collected in Java , Indonesia. Their chemical structures have been elucidated on the basis of physicochemical and chemical evidence.
