Abstract

The bark of Eucommia ulmoides is a well-known crude drug in oriental medicine, and its leaves have been consumed as a beverage. From the green leaves of this plant, three new iridoids (1-3) were isolated, together with 12 known compounds. Compound 1 is the first iridoid possessing a saturated bond between C-3 and C-4 and having an ether linkage between C-3 and C-2 of the glucose unit. Furthermore, 2 and 3 may be regarded as the first naturally occurring conjugates of an iridoid and an amino acid.
