title: A new abietane diterpenoid from Salvia xanthocheila Boiss.
abstract: From the chloroform extract of aerial part of Salvia xanthocheila Boiss. one new abietane diterpenoid, xantoquinone (5α,6α-dimethoxy-7,11,14-trioxoabieta-8,12-diene) and one known oleanene triterpenoid namely 1β,3β-dihydroxy-12-oleanene were isolated. The structure of the new terpenoid was elucidated by comprehensive spectroscopic analysis including electron ionisation-mass spectra, (1)H NMR, (13)C NMR, distortionless enchancement by polarisation transfer, H,H correlation spectroscopy, heteronuclear multiple-quantum coherence and heteronuclear multiple-bond correlation.
