Title: A New Abietane Diterpenoid from <i>Plectranthus bishopianus</i><scp>Benth</scp>.
Abstract: Abstract Chemical examination of the MeOH extract of Plectranthus bishopianus Benth ., a rare and endangered plant, resulted in isolation of a new abietane diterpene, 6 β ‐hydroxy‐7 α ‐methoxyroyleanone ( 1 ), along with two more diterpenoids, 6,7‐dehydroroyleanone, and 6 β ,7 α ‐dihydroxyroyleanone, a triterpene oleanolic acid, and two sterols, β ‐sistosterol and stigmasterol. The structures of the isolated compounds were elucidated on the basis of spectroscopic data and also by comparison with authentic samples.
