Bisabolane-type sesquiterpenes from the aerial parts of Lippia dulcis.
Six new bisabolane-type sesquiterpenes, peroxylippidulcines A-C (3-5), peroxyepilippidulcine B (6), and epilippidulcines B (7) and C (8), have been isolated from the aerial parts of Lippia dulcis, along with two known bisabolane-type sesquiterpenes, seven known flavonoids, and a known triterpenoid. The structures of 3-8 were characterized on the basis of NMR, MS, specific rotation, and X-ray crystallographic analysis data and chemical evidence.
